  Nikita Vasilevsky

• Dump the database schema containing the current Rails version.

  Since https://github.com/rails/rails/pull/42297, Rails now generate datetime columns
  with a default precision of 6. This means that users upgrading to Rails 7.0 from 6.1,
  when loading the database schema, would get the new precision value, which would not match
  the production schema.

  To avoid this the schema dumper will generate the new format which will include the Rails
  version and will look like this:

  ActiveRecord::Schema[7.0].define
  

  When upgrading from Rails 6.1 to Rails 7.0, you can run the rails app:update task that will
  set the current schema version to 6.1.

Active Job

• Allow testing discard_on/retry_on ActiveJob::DeserializationError

  Previously in perform_enqueued_jobs, deserialize_arguments_if_needed
  was called before calling perform_now. When a record no longer exists
  and is serialized using GlobalID this led to raising
  an ActiveJob::DeserializationError before reaching perform_now call.
  This behaviour makes difficult testing the job discard_on/retry_on logic.

  Now deserialize_arguments_if_needed call is postponed to when perform_now
  is called.

  Example:

  class UpdateUserJob < ActiveJob::Base
    discard_on ActiveJob::DeserializationError
  
    def perform(user)
      # ...
    end
  end
  
  # In the test
  User.destroy_all
  assert_nothing_raised do
    perform_enqueued_jobs only: UpdateUserJob
  end

Action Cable

• The Action Cable client now ensures successful channel subscriptions:

  • The client maintains a set of pending subscriptions until either
    the server confirms the subscription or the channel is torn down.
  • Rectifies the race condition where an unsubscribe is rapidly followed
    by a subscribe (on the same channel identifier) and the requests are
    handled out of order by the ActionCable server, thereby ignoring the
    subscribe command.

  Daniel Spinosa

• Compile ESM package that can be used directly in the browser as actioncable.esm.js.

  DHH

• Move action_cable.js to actioncable.js to match naming convention used for other Rails frameworks, and use JS console to communicate the deprecation.

  DHH

• Stop transpiling the UMD package generated as actioncable.js and drop the IE11 testing that relied on that.

  DHH

• Truncate broadcast logging messages.

  J Smith

• OpenSSL constants are now used for Digest computations.

  Dirkjan Bussink

• The Action Cable client now includes safeguards to prevent a "thundering
  herd" of client reconnects after server connectivity loss:

  • The client will wait a random amount between 1x and 3x of the stale
    threshold after the server's last ping before making the first
    reconnection attempt.
  • Subsequent reconnection attempts now use exponential backoff instead of
    logarithmic backoff. To allow the delay between reconnection attempts to
    increase slowly at first, the default exponentiation base is < 2.
  • Random jitter is applied to each delay between reconnection attempts.

  Jonathan Hefner

Action Mailbox

• Removed deprecated environment variable MAILGUN_INGRESS_API_KEY.

  Rafael Mendonça França

• Removed deprecated Rails.application.credentials.action_mailbox.mailgun_api_key.

• Add attachments to the list of permitted parameters for inbound emails conductor.

  When using the conductor to test inbound emails with attachments, this prevents an
  unpermitted parameter warning in default configurations, and prevents errors for
  applications that set:

  config.action_controller.action_on_unpermitted_parameters = :raise
  

  David Jones, Dana Henke

• Add ability to configure ActiveStorage service
  for storing email raw source.

  # config/storage.yml
  incoming_emails:
    service: Disk
    root: /secure/dir/for/emails/only
  

  config.action_mailbox.storage_service = :incoming_emails

  Étienne Barrié

• Instance variables set in requests in a ActionController::TestCase are now cleared before the next request

  This means if you make multiple requests in the same test, instance variables set in the first request will
  not persist into the second one. (It's not recommended to make multiple requests in the same test.)

  Alex Ghiculescu

• Rails.application.executor hooks can now be called around every request in a ActionController::TestCase

  This helps to better simulate request or job local state being reset between requests and prevent state
  leaking from one request to another.

  To enable this, set config.active_support.executor_around_test_case = true (this is the default in Rails 7).

  Alex Ghiculescu

• Raise ActionController::Redirecting::UnsafeRedirectError for unsafe redirect_to redirects.

  This allows rescue_from to be used to add a default fallback route:

  rescue_from ActionController::Redirecting::UnsafeRedirectError do
    redirect_to root_url
  end
  

  Kasper Timm Hansen, Chris Oliver

• Add url_from to verify a redirect location is internal.

  Takes the open redirect protection from redirect_to so users can wrap a
  param, and fall back to an alternate redirect URL when the param provided
  one is unsafe.

  def create
    redirect_to url_from(params[:redirect_url]) || root_url
  end
  

  dmcge, Kasper Timm Hansen

  Allow users to prevent conflicts among drivers that use the same driver
  type (selenium, poltergeist, webkit, rack test).

  Fixes #42502

  Chris LaRose

• Allow multiline to be passed in routes when using wildcard segments.

  Previously routes with newlines weren't detected when using wildcard segments, returning
  a No route matches error.
  After this change, routes with newlines are detected on wildcard segments. Example

    draw do
      get "/wildcard/*wildcard_segment", to: SimpleApp.new("foo#index"), as: :wildcard
    end
  
    # After the change, the path matches.
    assert_equal "/wildcard/a%0Anewline", url_helpers.wildcard_path(wildcard_segment: "a\nnewline")
  

  Fixes #39103

  Ignacio Chiazzo

• Treat html suffix in controller translation.

  Rui Onodera, Gavin Miller

• Allow permitting numeric params.

  Previously it was impossible to permit different fields on numeric parameters.
  After this change you can specify different fields for each numbered parameter.
  For example params like,

  book: {
          authors_attributes: {
            '0': { name: "William Shakespeare", age_of_death: "52" },
            '1': { name: "Unattributed Assistant" },
            '2': "Not a hash",
            'new_record': { name: "Some name" }
          }
        }
  

  Before you could permit name on each author with,
  permit book: { authors_attributes: [ :name ] }

  After this change you can permit different keys on each numbered element,
  permit book: { authors_attributes: { '1': [ :name ], '0': [ :name, :age_of_death ] } }

  Fixes #41625

  Adam Hess

• Update HostAuthorization middleware to render debug info only
  when config.consider_all_requests_local is set to true.

  Also, blocked host info is always logged with level error.

  Fixes #42813

  Nikita Vyrko

• Add Server-Timing middleware

  Server-Timing specification defines how the server can communicate to browsers performance metrics
  about the request it is responding to.

  The ServerTiming middleware is enabled by default on development environment by default using the
  config.server_timing setting and set the relevant duration metrics in the Server-Timing header

  The full specification for Server-Timing header can be found in: https://www.w3.org/TR/server-timing/#dfn-server-timing-header-field

  Sebastian Sogamoso, Guillermo Iguaran

• Use a static error message when raising ActionDispatch::Http::Parameters::ParseError
  to avoid inadvertently logging the HTTP request body at the fatal level when it contains
  malformed JSON.

  Fixes #41145

  Aaron Lahey

• Add Middleware#delete! to delete middleware or raise if not found.

  Middleware#delete! works just like Middleware#delete but will
  raise an error if the middleware isn't found.

  Alex Ghiculescu, Petrik de Heus, Junichi Sato

• Raise error on unpermitted open redirects.

  Add allow_other_host options to redirect_to.
  Opt in to this behaviour with ActionController::Base.raise_on_open_redirects = true.

  Gannon McGibbon

• Deprecate poltergeist and webkit (capybara-webkit) driver registration for system testing (they will be removed in Rails 7.1). Add cuprite instead.

  Poltergeist and capybara-webkit are already not maintained. These usage in Rails are removed for avoiding confusing users.

  Cuprite is a good alternative to Poltergeist. Some guide descriptions are replaced from Poltergeist to Cuprite.

  Yusuke Iwaki

• Exclude additional flash types from ActionController::Base.action_methods.

  Ensures that additional flash types defined on ActionController::Base subclasses
  are not listed as actions on that controller.

  class MyController < ApplicationController
    add_flash_types :hype
  end
  
  MyController.action_methods.include?('hype') # => false

• Remove IE6-7-8 file download related hack/fix from ActionController::DataStreaming module.

  Due to the age of those versions of IE this fix is no longer relevant, more importantly it creates an edge-case for unexpected Cache-Control headers.

  Tadas Sasnauskas

• Configuration setting to skip logging an uncaught exception backtrace when the exception is
  present in rescued_responses.

  It may be too noisy to get all backtraces logged for applications that manage uncaught
  exceptions via rescued_responses and exceptions_app.
  config.action_dispatch.log_rescued_responses (defaults to true) can be set to false in
  this case, so that only exceptions not found in rescued_responses will be logged.

    @subscribers.find_each do |subscriber|
      stream.writeln [ subscriber.email_address, subscriber.updated_at ].join(",")
    end
  end
  

  DHH

  Previously, ActionDispatch::Request#content_type returned value does NOT contain charset part.
  This behavior changed to returned Content-Type header containing charset part as it is.

  If you want just MIME type, please use ActionDispatch::Request#media_type instead.

  Before:

  request = ActionDispatch::Request.new("CONTENT_TYPE" => "text/csv; header=present; charset=utf-16", "REQUEST_METHOD" => "GET")
  request.content_type #=> "text/csv"
  

  After:

  request = ActionDispatch::Request.new("Content-Type" => "text/csv; header=present; charset=utf-16", "REQUEST_METHOD" => "GET")
  request.content_type #=> "text/csv; header=present; charset=utf-16"

  #       <strong>Save as draft</strong>
  #     </button>
  

  Sean Doyle

• Introduce the field_name view helper, along with the
  FormBuilder#field_name counterpart:

  form_for @post do |f|
    f.field_tag :tag, name: f.field_name(:tag, multiple: true)
    # => <input type="text" name="post[tag][]">
  end
  

  Sean Doyle

• Execute the ActionView::Base.field_error_proc within the context of the
  ActionView::Base instance:

  config.action_view.field_error_proc = proc { |html| content_tag(:div, html, class: "field_with_errors") }
  

  Sean Doyle

• Add support for button_to ..., authenticity_token: false

  button_to "Create", Post.new, authenticity_token: false
  # => <form class="button_to" method="post" action="/posts"><button type="submit">Create</button></form>
  
  button_to "Create", Post.new, authenticity_token: true
  # => <form class="button_to" method="post" action="/posts"><button type="submit">Create</button><input type="hidden" name="form_token" value="abc123..." autocomplete="off" /></form>
  
  button_to "Create", Post.new, authenticity_token: "secret"
  # => <form class="button_to" method="post" action="/posts"><button type="submit">Create</button><input type="hidden" name="form_token" value="secret" autocomplete="off" /></form>
  

  Sean Doyle

• Support rendering <form> elements without [action] attributes by:

  • form_with url: false or form_with ..., html: { action: false }
  • form_for ..., url: false or form_for ..., html: { action: false }
  • form_tag false or form_tag ..., action: false
  • button_to "...", false or button_to(false) { ... }

  Sean Doyle

• Add :day_format option to date_select

  date_select("article", "written_on", day_format: ->(day) { day.ordinalize })
  # generates day options like <option value="1">1st</option>\n<option value="2">2nd</option>...
  

  Shunichi Ikegami

• Allow link_to helper to infer link name from Model#to_s when it
  is used with a single argument:

  link_to @profile
  #=> <a href="/profiles/1">Eileen</a>
  

  This assumes the model class implements a to_s method like this:

  class Profile < ApplicationRecord
    # ...
    def to_s
      name
    end
  end
  

  Previously you had to supply a second argument even if the Profile
  model implemented a #to_s method that called the name method.

  link_to @profile, @profile.name
  #=> <a href="/profiles/1">Eileen</a>
  

  Olivier Lacan

• Support svg unpaired tags for tag helper.

  tag.svg { tag.use('href' => "#cool-icon") }
  # => <svg><use href="#cool-icon"></svg>
  

  Oleksii Vasyliev

• Improves the performance of ActionView::Helpers::NumberHelper formatters by avoiding the use of
  exceptions as flow control.

  Mike Dalessio

• preload_link_tag properly inserts as attributes for files with image MIME types, such as JPG or SVG.

  Nate Berkopec

• Add weekday_options_for_select and weekday_select helper methods. Also adds weekday_select to FormBuilder.

  Drew Bragg, Dana Kashubeck, Kasper Timm Hansen

• Add caching? helper that returns whether the current code path is being cached and uncacheable! to denote helper methods that can't participate in fragment caching.

  Ben Toews, John Hawthorn, Kasper Timm Hansen, Joel Hawksley

• Add include_seconds option for time_field.

  <%= form.time_field :foo, include_seconds: false %>
  # => <input value="16:22" type="time" />
  

  Default includes seconds:

  <%= form.time_field :foo %>
  # => <input value="16:22:01.440" type="time" />
  

  This allows you to take advantage of different rendering options in some browsers.

  Alex Ghiculescu

• Improve error messages when template file does not exist at absolute filepath.

  Ted Whang

• Add :country_code option to sms_to for consistency with phone_to.

  Jonathan Hefner

• OpenSSL constants are now used for Digest computations.

  Dirkjan Bussink

• The translate helper now passes default values that aren't
  translation keys through I18n.translate for interpolation.

  Jonathan Hefner

• Adds option extname to stylesheet_link_tag to skip default
  .css extension appended to the stylesheet path.

  Before:

  stylesheet_link_tag "style.less"
  # <link href="/stylesheets/style.less.scss" rel="stylesheet">
  

  After:

  stylesheet_link_tag "style.less", extname: false, skip_pipeline: true, rel: "stylesheet/less"
  # <link href="/stylesheets/style.less" rel="stylesheet/less">
  

  Abhay Nikam

• Deprecate render locals to be assigned to instance variables.

  Petrik de Heus

• Remove legacy default media=screen from stylesheet_link_tag.

  André Luis Leal Cardoso Junior

• Change ActionView::Helpers::FormBuilder#button to transform formmethod
  attributes into _method="$VERB" Form Data to enable varied same-form actions:

  <%= form_with model: post, method: :put do %>
    <%= form.button "Update" %>
    <%= form.button "Delete", formmethod: :delete %>
  <% end %>
  <%# => <form action="posts/1">
      =>   <input type="hidden" name="_method" value="put">
      =>   <button type="submit">Update</button>
      =>   <button type="submit" formmethod="post" name="_method" value="delete">Delete</button>
      => </form>
  %>
  

  Sean Doyle

• Change ActionView::Helpers::UrlHelper#button_to to always render a
  <button> element, regardless of whether or not the content is passed as
  the first argument or as a block.

  <%= button_to "Delete", post_path(@post), method: :delete %>
  # => <form action="/posts/1"><input type="hidden" name="_method" value="delete"><button type="submit">Delete</button></form>
  
  <%= button_to post_path(@post), method: :delete do %>
    Delete
  <% end %>
  # => <form action="/posts/1"><input type="hidden" name="_method" value="delete"><button type="submit">Delete</button></form>
  

  Sean Doyle, Dusan Orlovic

• Add config.action_view.preload_links_header to allow disabling of
  the Link header being added by default when using stylesheet_link_tag
  and javascript_include_tag.

  Andrew White

• The translate helper now resolves default values when a nil key is
  specified, instead of always returning nil.

  Jonathan Hefner

• Add config.action_view.image_loading to configure the default value of
  the image_tag :loading option.

  By setting config.action_view.image_loading = "lazy", an application can opt in to
  lazy loading images sitewide, without changing view code.

  Jonathan Hefner

• ActionView::Helpers::FormBuilder#id returns the value
  of the <form> element's id attribute. With a method argument, returns
  the id attribute for a form field with that name.

  <%= form_for @post do |f| %>
    <%# ... %>
  
    <% content_for :sticky_footer do %>
      <%= form.button(form: f.id) %>
    <% end %>
  <% end %>
  

  Sean Doyle

• ActionView::Helpers::FormBuilder#field_id returns the value generated by
  the FormBuilder for the given attribute name.

  <%= form_for @post do |f| %>
    <%= f.label :title %>
    <%= f.text_field :title, aria: { describedby: f.field_id(:title, :error) } %>
    <%= tag.span("is blank", id: f.field_id(:title, :error) %>
  <% end %>
  

  Sean Doyle

• Add tag.attributes to transform a Hash into HTML Attributes, ready to be
  interpolated into ERB.

  <input <%= tag.attributes(type: :text, aria: { label: "Search" }) %> >
  # => <input type="text" aria-label="Search">

Active Job

• Remove deprecated :return_false_on_aborted_enqueue option.

  Rafael Mendonça França

• Deprecated Rails.config.active_job.skip_after_callbacks_if_terminated.

  Rafael Mendonça França

• Removed deprecated behavior that was not halting after_enqueue/after_perform callbacks when a
  previous callback was halted with throw :abort.

  Rafael Mendonça França

• Raise an SerializationError in Serializer::ModuleSerializer
  if the module name is not present.

  Veerpal Brar

• Allow a job to retry indefinitely

  The attempts parameter of the retry_on method now accepts the
  symbol reference :unlimited in addition to a specific number of retry
  attempts to allow a developer to specify that a job should retry
  forever until it succeeds.

  class MyJob < ActiveJob::Base
    retry_on(AlwaysRetryException, attempts: :unlimited)
  
    # the actual job code
  end
  

  Daniel Morton

• Added possibility to check on :priority in test helper methods
  assert_enqueued_with and assert_performed_with.

  Wojciech Wnętrzak

• OpenSSL constants are now used for Digest computations.

  Dirkjan Bussink

• Add a Serializer for the Range class.

  This should allow things like MyJob.perform_later(range: 1..100).

• Communicate enqueue failures to callers of perform_later.

  perform_later can now optionally take a block which will execute after
  the adapter attempts to enqueue the job. The block will receive the job
  instance as an argument even if the enqueue was not successful.
  Additionally, ActiveJob adapters now have the ability to raise an
  ActiveJob::EnqueueError which will be caught and stored in the job
  instance so code attempting to enqueue jobs can inspect any raised
  EnqueueError using the block.

  MyJob.perform_later do |job|
    unless job.successfully_enqueued?
      if job.enqueue_error&.message == "Redis was unavailable"
        # invoke some code that will retry the job after a delay
      end
    end
  end
  

  Daniel Morton

• Don't log rescuable exceptions defined with rescue_from.

  Hu Hailin

• Allow rescue_from to rescue all exceptions.

  Rafael Mendonça França

• Remove deprecated ActiveModel::Errors#keys.

  Rafael Mendonça França

• Remove deprecated ActiveModel::Errors#values.

  Rafael Mendonça França

• Remove deprecated ActiveModel::Errors#slice!.

  Rafael Mendonça França

• Remove deprecated ActiveModel::Errors#to_h.

  Rafael Mendonça França

• Remove deprecated enumeration of ActiveModel::Errors instances as a Hash.

  Rafael Mendonça França

• Clear secure password cache if password is set to nil

  Before:

  user.password = 'something'
  user.password = nil

  user.password # => 'something'

  Now:

  user.password = 'something'
  user.password = nil

  user.password # => nil

  Markus Doits

• Introduce ActiveModel::API.

  Make ActiveModel::API the minimum API to talk with Action Pack and Action View.
  This will allow adding more functionality to ActiveModel::Model.

  Petrik de Heus, Nathaniel Watts

• Fix dirty check for Float::NaN and BigDecimal::NaN.

  Float::NaN and BigDecimal::NaN in Ruby are special values
  and can't be compared with ==.

  Marcelo Lauxen

• Fix to_json for ActiveModel::Dirty object.

  Exclude mutations_from_database attribute from json as it lead to recursion.

  Anil Maurya

• Add ActiveModel::AttributeSet#values_for_database.

  Returns attributes with values for assignment to the database.

  Chris Salzberg

• Fix delegation in ActiveModel::Type::Registry#lookup and ActiveModel::Type.lookup.

  Passing a last positional argument {} would be incorrectly considered as keyword argument.

  Benoit Daloze

• Cache and re-use generated attribute methods.

  Generated methods with identical implementations will now share their instruction sequences
  leading to reduced memory retention, and slightly faster load time.

  Jean Boussier

• Add in: range parameter to numericality validator.

  Michal Papis

• Add locale argument to ActiveModel::Name#initialize to be used to generate the singular,
  plural, route_key and singular_route_key values.

  Lukas Pokorny

• Make ActiveModel::Errors#inspect slimmer for readability

  lulalala

Active Record

• Better handle SQL queries with invalid encoding.

  Post.create(name: "broken \xC8 UTF-8")
  

  Would cause all adapters to fail in a non controlled way in the code
  responsible to detect write queries.

  The query is now properly passed to the database connection, which might or might
  not be able to handle it, but will either succeed or failed in a more correct way.

  Jean Boussier

• Move database and shard selection config options to a generator.

  Rather than generating the config options in production.rb when applications are created, applications can now run a generator to create an initializer and uncomment / update options as needed. All multi-db configuration can be implemented in this initializer.

  Eileen M. Uchitelle

• Remove deprecated ActiveRecord::DatabaseConfigurations::DatabaseConfig#spec_name.

  Rafael Mendonça França

• Remove deprecated ActiveRecord::Connection#in_clause_length.

  Rafael Mendonça França

• Remove deprecated ActiveRecord::Connection#allowed_index_name_length.

  Rafael Mendonça França

• Remove deprecated ActiveRecord::Base#remove_connection.

  Rafael Mendonça França

• Load STI Models in fixtures

  Data from Fixtures now loads based on the specific class for models with
  Single Table Inheritance. This affects enums defined in subclasses, previously
  the value of these fields was not parsed and remained nil

  Andres Howard

• #authenticate returns false when the password is blank instead of raising an error.

  Muhammad Muhammad Ibrahim

• Fix ActiveRecord::QueryMethods#in_order_of behavior for integer enums.

  ActiveRecord::QueryMethods#in_order_of didn't work as expected for enums stored as integers in the database when passing an array of strings or symbols as the order argument. This unexpected behavior occurred because the string or symbol values were not casted to match the integers in the database.

  The following example now works as expected:

  class Book < ApplicationRecord
    enum status: [:proposed, :written, :published]
  end
  
  Book.in_order_of(:status, %w[written published proposed])
  

  Alexandre Ruban

• Ignore persisted in-memory records when merging target lists.

  Kevin Sjöberg

• Add a new option :update_only to upsert_all to configure the list of columns to update in case of conflict.

  Before, you could only customize the update SQL sentence via :on_duplicate. There is now a new option :update_only that lets you provide a list of columns to update in case of conflict:

  Commodity.upsert_all(
    [
      { id: 2, name: "Copper", price: 4.84 },
      { id: 4, name: "Gold", price: 1380.87 },
      { id: 6, name: "Aluminium", price: 0.35 }
    ],
    update_only: [:price] # Only prices will be updated
  )
  

  Jorge Manrubia

• Remove deprecated ActiveRecord::Result#map! and ActiveRecord::Result#collect!.

  Rafael Mendonça França

• Remove deprecated ActiveRecord::Base.configurations.to_h.

  Rafael Mendonça França

• Remove deprecated ActiveRecord::Base.configurations.default_hash.

  Rafael Mendonça França

• Remove deprecated ActiveRecord::Base.arel_attribute.

  Rafael Mendonça França

• Remove deprecated ActiveRecord::Base.connection_config.

  Rafael Mendonça França

• Filter attributes in SQL logs

  Previously, SQL queries in logs containing ActiveRecord::Base.filter_attributes were not filtered.

  Now, the filter attributes will be masked [FILTERED] in the logs when prepared_statement is enabled.

  # Before:
    Foo Load (0.2ms)  SELECT "foos".* FROM "foos" WHERE "foos"."passw" = ? LIMIT ?  [["passw", "hello"], ["LIMIT", 1]]
  
  # After:
    Foo Load (0.5ms)  SELECT "foos".* FROM "foos" WHERE "foos"."passw" = ? LIMIT ?  [["passw", "[FILTERED]"], ["LIMIT", 1]]

  Rafael Mendonça França

• Deprecate Tasks::DatabaseTasks.schema_file_type.

  Rafael Mendonça França

• Remove deprecated Tasks::DatabaseTasks.dump_filename.

  Rafael Mendonça França

• Remove deprecated Tasks::DatabaseTasks.schema_file.

  Rafael Mendonça França

• Remove deprecated environment and name arguments from Tasks::DatabaseTasks.schema_up_to_date?.

  Rafael Mendonça França

• Merging conditions on the same column no longer maintain both conditions,
  and will be consistently replaced by the latter condition.

  # Rails 6.1 (IN clause is replaced by merger side equality condition)
  Author.where(id: [david.id, mary.id]).merge(Author.where(id: bob)) # => [bob]
  # Rails 6.1 (both conflict conditions exists, deprecated)
  Author.where(id: david.id..mary.id).merge(Author.where(id: bob)) # => []
  # Rails 6.1 with rewhere to migrate to Rails 7.0's behavior
  Author.where(id: david.id..mary.id).merge(Author.where(id: bob), rewhere: true) # => [bob]
  # Rails 7.0 (same behavior with IN clause, mergee side condition is consistently replaced)
  Author.where(id: [david.id, mary.id]).merge(Author.where(id: bob)) # => [bob]
  Author.where(id: david.id..mary.id).merge(Author.where(id: bob)) # => [bob]

• Remove deprecated support to Model.reorder(nil).first to search using non-deterministic order.

  Rafael Mendonça França

• Remove deprecated rake tasks:

  • db:schema:load_if_ruby
  • db:structure:dump
  • db:structure:load
  • db:structure:load_if_sql
  • db:structure:dump:#{name}
  • db:structure:load:#{name}
  • db:test:load_structure
  • db:test:load_structure:#{name}

  Rafael Mendonça França

• Remove deprecated DatabaseConfig#config method.

  Rafael Mendonça França

• Rollback transactions when the block returns earlier than expected.

  Before this change, when a transaction block returned early, the transaction would be committed.

  The problem is that timeouts triggered inside the transaction block was also making the incomplete transaction
  to be committed, so in order to avoid this mistake, the transaction block is rolled back.

  Rafael Mendonça França

• Add middleware for automatic shard swapping.

  Provides a basic middleware to perform automatic shard swapping. Applications will provide a resolver which will determine for an individual request which shard should be used. Example:

  config.active_record.shard_resolver = ->(request) {
    subdomain = request.subdomain
    tenant = Tenant.find_by_subdomain!(subdomain)
    tenant.shard
  }
  

  See guides for more details.

  Eileen M. Uchitelle, John Crepezzi

• Remove deprecated support to pass a column to type_cast.

  Rafael Mendonça França

• Remove deprecated support to type cast to database values ActiveRecord::Base objects.

  Rafael Mendonça França

• Remove deprecated support to quote ActiveRecord::Base objects.

  Rafael Mendonça França

• Remove deprecacated support to resolve connection using "primary" as connection specification name.

  Rafael Mendonça França

• Remove deprecation warning when using :interval column is used in PostgreSQL database.

  Now, interval columns will return ActiveSupport::Duration objects instead of strings.

  To keep the old behavior, you can add this line to your model:

  attribute :column, :string
  

  Rafael Mendonça França

• Remove deprecated support to YAML load ActiveRecord::Base instance in the Rails 4.2 and 4.1 formats.

  Rafael Mendonça França

• Remove deprecated option :spec_name in the configs_for method.

  Rafael Mendonça França

• Remove deprecated ActiveRecord::Base.allow_unsafe_raw_sql.

  Rafael Mendonça França

• Fix regression bug that caused ignoring additional conditions for preloading has_many-through relations.

  Fixes #43132

  Alexander Pauly

• Fix has_many inversing recursion on models with recursive associations.

  Gannon McGibbon

• Add accepts_nested_attributes_for support for delegated_type

  class Entry < ApplicationRecord
    delegated_type :entryable, types: %w[ Message Comment ]
    accepts_nested_attributes_for :entryable
  end
  
  entry = Entry.create(entryable_type: 'Message', entryable_attributes: { content: 'Hello world' })
  # => #<Entry:0x00>
  # id: 1
  # entryable_id: 1,
  # entryable_type: 'Message'
  # ...>
  
  entry.entryable
  # => #<Message:0x01>
  # id: 1
  # content: 'Hello world'
  # ...>
  

  Previously it would raise an error:

  Entry.create(entryable_type: 'Message', entryable_attributes: { content: 'Hello world' })
  # ArgumentError: Cannot build association `entryable'. Are you trying to build a polymorphic one-to-one association?
  

  Sjors Baltus

• Use subquery for DELETE with GROUP_BY and HAVING clauses.

  Prior to this change, deletes with GROUP_BY and HAVING were returning an error.

  After this change, GROUP_BY and HAVING are valid clauses in DELETE queries, generating the following query:

  DELETE FROM "posts" WHERE "posts"."id" IN (
      SELECT "posts"."id" FROM "posts" INNER JOIN "comments" ON "comments"."post_id" = "posts"."id" GROUP BY "posts"."id" HAVING (count(comments.id) >= 2))
  )  [["flagged", "t"]]
  

  Ignacio Chiazzo Cardarello

• Use subquery for UPDATE with GROUP_BY and HAVING clauses.

  Prior to this change, updates with GROUP_BY and HAVING were being ignored, generating a SQL like this:

  UPDATE "posts" SET "flagged" = ? WHERE "posts"."id" IN (
      SELECT "posts"."id" FROM "posts" INNER JOIN "comments" ON "comments"."post_id" = "posts"."id"
  )  [["flagged", "t"]]
  

  After this change, GROUP_BY and HAVING clauses are used as a subquery in updates, like this:

  UPDATE "posts" SET "flagged" = ? WHERE "posts"."id" IN (
      SELECT "posts"."id" FROM "posts" INNER JOIN "comments" ON "comments"."post_id" = "posts"."id"
      GROUP BY posts.id HAVING (count(comments.id) >= 2)
  )  [["flagged", "t"]]
  

  Ignacio Chiazzo Cardarello

• Add support for setting the filename of the schema or structure dump in the database config.

  Applications may now set their the filename or path of the schema / structure dump file in their database configuration.

  production:
    primary:
      database: my_db
      schema_dump: my_schema_dump_filename.rb
    animals:
      database: animals_db
      schema_dump: false
  

  The filename set in schema_dump will be used by the application. If set to false the schema will not be dumped. The database tasks are responsible for adding the database directory to the filename. If a full path is provided, the Rails tasks will use that instead of ActiveRecord::DatabaseTasks.db_dir.

  Eileen M. Uchitelle, Ryan Kerr

• Add ActiveRecord::Base.prohibit_shard_swapping to prevent attempts to change the shard within a block.

  John Crepezzi, Eileen M. Uchitelle

• Filter unchanged attributes with default function from insert query when partial_inserts is disabled.

  Akshay Birajdar, Jacopo Beschi

• Add support for FILTER clause (SQL:2003) to Arel.

  Currently supported by PostgreSQL 9.4+ and SQLite 3.30+.

  Andrey Novikov

• Automatically set timestamps on record creation during bulk insert/upsert

  Prior to this change, only updates during an upsert operation (e.g. upsert_all) would touch timestamps (updated_{at,on}). Now, record creations also touch timestamp columns ({created,updated}_{at,on}).

  This behaviour is controlled by the <model>.record_timestamps config, matching the behaviour of create, update, etc. It can also be overridden by using the record_timestamps: keyword argument.

  Note that this means upsert_all on models with record_timestamps = false will no longer touch updated_{at,on} automatically.

  Sam Bostock

• Don't require role when passing shard to connected_to.

  connected_to can now be called with a shard only. Note that role is still inherited if connected_to calls are nested.

  Eileen M. Uchitelle

• Add option to lazily load the schema cache on the connection.

  Previously, the only way to load the schema cache in Active Record was through the Railtie on boot. This option provides the ability to load the schema cache on the connection after it's been established. Loading the cache lazily on the connection can be beneficial for Rails applications that use multiple databases because it will load the cache at the time the connection is established. Currently Railties doesn't have access to the connections before boot.

  To use the cache, set config.active_record.lazily_load_schema_cache = true in your application configuration. In addition a schema_cache_path should be set in your database configuration if you don't want to use the default "db/schema_cache.yml" path.

  Eileen M. Uchitelle

• Allow automatic inverse_of detection for associations with scopes.

  Automatic inverse_of detection now works for associations with scopes. For
  example, the comments association here now automatically detects
  inverse_of: :post, so we don't need to pass that option:

  class Post < ActiveRecord::Base
    has_many :comments, -> { visible }
  end
  
  class Comment < ActiveRecord::Base
    belongs_to :post
  end
  

  Note that the automatic detection still won't work if the inverse
  association has a scope. In this example a scope on the post association
  would still prevent Rails from finding the inverse for the comments
  association.

  This will be the default for new apps in Rails 7. To opt in:

  config.active_record.automatic_scope_inversing = true
  

  Daniel Colson, Chris Bloom

• Accept optional transaction args to ActiveRecord::Locking::Pessimistic#with_lock

  #with_lock now accepts transaction options like requires_new:,
  isolation:, and joinable:

  John Mileham

• Adds support for deferrable foreign key constraints in PostgreSQL.

  By default, foreign key constraints in PostgreSQL are checked after each statement. This works for most use cases,
  but becomes a major limitation when creating related records before the parent record is inserted into the database.
  One example of this is looking up / creating a person via one or more unique alias.

  Person.transaction do
    alias = Alias
      .create_with(user_id: SecureRandom.uuid)
      .create_or_find_by(name: "DHH")
  
    person = Person
      .create_with(name: "David Heinemeier Hansson")
      .create_or_find_by(id: alias.user_id)
  end
  

  Using the default behavior, the transaction would fail when executing the first INSERT statement.

  By passing the :deferrable option to the add_foreign_key statement in migrations, it's possible to defer this
  check.

  add_foreign_key :aliases, :person, deferrable: true
  

  Passing deferrable: true doesn't change the default behavior, but allows manually deferring the check using
  SET CONSTRAINTS ALL DEFERRED within a transaction. This will cause the foreign keys to be checked after the
  transaction.

  It's also possible to adjust the default behavior from an immediate check (after the statement), to a deferred check
  (after the transaction):

  add_foreign_key :aliases, :person, deferrable: :deferred
  

  Benedikt Deicke

• Allow configuring Postgres password through the socket URL.

  For example:

  ActiveRecord::DatabaseConfigurations::UrlConfig.new(
    :production, :production, 'postgres:///?user=user&password=secret&dbname=app', {}
  ).configuration_hash
  

  will now return,

  { :user=>"user", :password=>"secret", :dbname=>"app", :adapter=>"postgresql" }
  

  Abeid Ahmed

• PostgreSQL: support custom enum types

  In migrations, use create_enum to add a new enum type, and t.enum to add a column.

  def up
    create_enum :mood, ["happy", "sad"]
  
    change_table :cats do |t|
      t.enum :current_mood, enum_type: "mood", default: "happy", null: false
    end
  end
  

  Enums will be presented correctly in schema.rb. Note that this is only supported by
  the PostgreSQL adapter.

• Avoid COMMENT statements in PostgreSQL structure dumps

  COMMENT statements are now omitted from the output of db:structure:dump when using PostgreSQL >= 11.
  This allows loading the dump without a pgsql superuser account.

  Fixes #36816, #43107.

• Add support for generated columns in PostgreSQL adapter

  Generated columns are supported since version 12.0 of PostgreSQL. This adds
  support of those to the PostgreSQL adapter.

  create_table :users do |t|
    t.string :name
    t.virtual :name_upcased, type: :string, as: 'upper(name)', stored: true
  end

• Remove warning when overwriting existing scopes

  Removes the following unnecessary warning message that appeared when overwriting existing scopes

  Creating scope :my_scope_name. Overwriting existing method "MyClass.my_scope_name" when overwriting existing scopes

• Use full precision for updated_at in insert_all/upsert_all

  CURRENT_TIMESTAMP provides differing precision depending on the database,
  and not all databases support explicitly specifying additional precision.

  Instead, we delegate to the new connection.high_precision_current_timestamp
  for the SQL to produce a high precision timestamp on the current database.

  Fixes #42992

  Sam Bostock

• Add ssl support for postgresql database tasks

  Add PGSSLMODE, PGSSLCERT, PGSSLKEY and PGSSLROOTCERT to pg_env from database config
  when running postgresql database tasks.

  # config/database.yml
  
  production:
    sslmode: verify-full
    sslcert: client.crt
    sslkey: client.key
    sslrootcert: ca.crt
  

  Environment variables

  PGSSLMODE=verify-full
  PGSSLCERT=client.crt
  PGSSLKEY=client.key
  PGSSLROOTCERT=ca.crt
  

  Fixes #42994

• Avoid scoping update callbacks in ActiveRecord::Relation#update!.

  Making it consistent with how scoping is applied only to the query in ActiveRecord::Relation#update
  and not also to the callbacks from the update itself.

  Dylan Thacker-Smith

• Fix 2 cases that inferred polymorphic class from the association's foreign_type
  using String#constantize instead of the model's polymorphic_class_for.

  When updating a polymorphic association, the old foreign_type was not inferred correctly when:

  1. touching the previously associated record
  2. updating the previously associated record's counter_cache

  Jimmy Bourassa

• Add config option for ignoring tables when dumping the schema cache.

  Applications can now be configured to ignore certain tables when dumping the schema cache.

  The configuration option can table an array of tables:

  config.active_record.schema_cache_ignored_tables = ["ignored_table", "another_ignored_table"]
  

  Or a regex:

  config.active_record.schema_cache_ignored_tables = [/^_/]
  

  Eileen M. Uchitelle

• Make schema cache methods return consistent results.

  Previously the schema cache methods primary_keys, columns, columns_hash, and indexes
  would behave differently than one another when a table didn't exist and differently across
  database adapters. This change unifies the behavior so each method behaves the same regardless
  of adapter.

  The behavior now is:

  columns: (unchanged) raises a db error if the table does not exist.
  columns_hash: (unchanged) raises a db error if the table does not exist.
  primary_keys: (unchanged) returns nil if the table does not exist.
  indexes: (changed for mysql2) returns [] if the table does not exist.

• Reestablish connection to previous database after after running db:schema:load:name

  After running db:schema:load:name the previous connection is restored.

  Jacopo Beschi

• Add database config option database_tasks

  If you would like to connect to an external database without any database
  management tasks such as schema management, migrations, seeds, etc. you can set
  the per database config option database_tasks: false

  # config/database.yml
  
  production:
    primary:
      database: my_database
      adapter: mysql2
    animals:
      database: my_animals_database
      adapter: mysql2
      database_tasks: false
  

  Weston Ganger

• Fix ActiveRecord::InternalMetadata to not be broken by config.active_record.record_timestamps = false

  Since the model always create the timestamp columns, it has to set them, otherwise it breaks
  various DB management tasks.

  Fixes #42983

• Add ActiveRecord::QueryLogs.

  Configurable tags can be automatically added to all SQL queries generated by Active Record.

  # config/application.rb
  module MyApp
    class Application < Rails::Application
      config.active_record.query_log_tags_enabled = true
    end
  end
  

  By default the application, controller and action details are added to the query tags:

  class BooksController < ApplicationController
    def index
      @books = Book.all
    end
  end
  

  GET /books
  # SELECT * FROM books /*application:MyApp;controller:books;action:index*/
  

  Custom tags containing static values and Procs can be defined in the application configuration:

  config.active_record.query_log_tags = [
    :application,
    :controller,
    :action,
    {
      custom_static: "foo",
      custom_dynamic: -> { Time.now }
    }
  ]

• Added support for multiple databases to rails db:setup and rails db:reset.

  Ryan Hall

• Add ActiveRecord::Relation#structurally_compatible?.

  Adds a query method by which a user can tell if the relation that they're
  about to use for #or or #and is structurally compatible with the
  receiver.

  Kevin Newton

• Add ActiveRecord::QueryMethods#in_order_of.

  This allows you to specify an explicit order that you'd like records
  returned in based on a SQL expression. By default, this will be accomplished
  using a case statement, as in:

  Post.in_order_of(:id, [3, 5, 1])
  

  will generate the SQL:

  SELECT "posts".* FROM "posts" ORDER BY CASE "posts"."id" WHEN 3 THEN 1 WHEN 5 THEN 2 WHEN 1 THEN 3 ELSE 4 END ASC
  

  However, because this functionality is built into MySQL in the form of the
  FIELD function, that connection adapter will generate the following SQL
  instead:

  SELECT "posts".* FROM "posts" ORDER BY FIELD("posts"."id", 1, 5, 3) DESC
  

  Kevin Newton

• Fix eager_loading? when ordering with Symbol.

  eager_loading? is triggered correctly when using order with symbols.

  scope = Post.includes(:comments).order(:"comments.label")
  => true
  

  Jacopo Beschi

• Two change tracking methods are added for belongs_to associations.

  The association_changed? method (assuming an association named :association) returns true
  if a different associated object has been assigned and the foreign key will be updated in the
  next save.

  The association_previously_changed? method returns true if the previous save updated the
  association to reference a different associated object.

  George Claghorn

• Add option to disable schema dump per-database.

  Dumping the schema is on by default for all databases in an application. To turn it off for a
  specific database, use the schema_dump option:

  # config/database.yml
  
  production:
    schema_dump: false
  

  Luis Vasconcellos, Eileen M. Uchitelle

• Fix eager_loading? when ordering with Hash syntax.

  eager_loading? is triggered correctly when using order with hash syntax
  on an outer table.

  Post.includes(:comments).order({ "comments.label": :ASC }).eager_loading?
  # => true

• Move the forcing of clear text encoding to the ActiveRecord::Encryption::Encryptor.

  Fixes #42699.

  J Smith

• partial_inserts is now disabled by default in new apps.

  This will be the default for new apps in Rails 7. To opt in:

  config.active_record.partial_inserts = true
  

  If a migration removes the default value of a column, this option
  would cause old processes to no longer be able to create new records.

  If you need to remove a column, you should first use ignored_columns
  to stop using it.

  Jean Boussier

• Rails can now verify foreign keys after loading fixtures in tests.

  This will be the default for new apps in Rails 7. To opt in:

  config.active_record.verify_foreign_keys_for_fixtures = true
  

  Tests will not run if there is a foreign key constraint violation in your fixture data.

  The feature is supported by SQLite and PostgreSQL, other adapters can also add support for it.

  Alex Ghiculescu

• Clear cached has_one association after setting belongs_to association to nil.

  After setting a belongs_to relation to nil and updating an unrelated attribute on the owner,
  the owner should still return nil on the has_one relation.

  Fixes #42597.

  Michiel de Mare

• OpenSSL constants are now used for Digest computations.

  Dirkjan Bussink

• Adds support for if_not_exists to add_foreign_key and if_exists to remove_foreign_key.

  Applications can set their migrations to ignore exceptions raised when adding a foreign key
  that already exists or when removing a foreign key that does not exist.

  Example Usage:

  class AddAuthorsForeignKeyToArticles < ActiveRecord::Migration[7.0]
    def change
      add_foreign_key :articles, :authors, if_not_exists: true
    end
  end
  

  class RemoveAuthorsForeignKeyFromArticles < ActiveRecord::Migration[7.0]
    def change
      remove_foreign_key :articles, :authors, if_exists: true
    end
  end
  

  Roberto Miranda

• Prevent polluting ENV during postgresql structure dump/load.

  Some configuration parameters were provided to pg_dump / psql via
  environment variables which persisted beyond the command being run, and may
  have caused subsequent commands and connections to fail. Tasks running
  across multiple postgresql databases like rails db:test:prepare may have
  been affected.

  Samuel Cochran

• Set precision 6 by default for datetime columns.

  By default, datetime columns will have microseconds precision instead of seconds precision.

• Do not try to rollback transactions that failed due to a ActiveRecord::TransactionRollbackError.

  Jamie McCarthy

• Active Record Encryption will now encode values as UTF-8 when using deterministic
  encryption. The encoding is part of the encrypted payload, so different encodings for
  different values result in different ciphertexts. This can break unique constraints and
  queries.

  The new behavior is configurable via active_record.encryption.forced_encoding_for_deterministic_encryption
  that is Encoding::UTF_8 by default. It can be disabled by setting it to nil.

  Jorge Manrubia

• The MySQL adapter now cast numbers and booleans bind parameters to string for safety reasons.

  When comparing a string and a number in a query, MySQL converts the string to a number. So for
  instance "foo" = 0, will implicitly cast "foo" to 0 and will evaluate to TRUE which can
  lead to security vulnerabilities.

  Active Record already protect against that vulnerability when it knows the type of the column
  being compared, however until now it was still vulnerable when using bind parameters:

  User.where("login_token = ?", 0).first
  

  Would perform:

  SELECT * FROM `users` WHERE `login_token` = 0 LIMIT 1;
  

  Now it will perform:

  SELECT * FROM `users` WHERE `login_token` = '0' LIMIT 1;
  

  Jean Boussier

• Fixture configurations (_fixture) are now strictly validated.

  If an error will be raised if that entry contains unknown keys while previously it
  would silently have no effects.

  Jean Boussier

• Add ActiveRecord::Base.update! that works like ActiveRecord::Base.update but raises exceptions.

  This allows for the same behavior as the instance method #update! at a class level.

  Person.update!(:all, state: "confirmed")
  

  Dorian Marié

• Add ActiveRecord::Base#attributes_for_database.

  Returns attributes with values for assignment to the database.

  Chris Salzberg

• Use an empty query to check if the PostgreSQL connection is still active.

  An empty query is faster than SELECT 1.

  Heinrich Lee Yu

• Add ActiveRecord::Base#previously_persisted?.

  Returns true if the object has been previously persisted but now it has been deleted.

• Deprecate partial_writes in favor of partial_inserts and partial_updates.

  This allows to have a different behavior on update and create.

  Jean Boussier

• Fix compatibility with psych >= 4.

  Starting in Psych 4.0.0 YAML.load behaves like YAML.safe_load. To preserve compatibility,
  Active Record's schema cache loader and YAMLColumn now uses YAML.unsafe_load if available.

  Jean Boussier

• ActiveRecord::Base.logger is now a class_attribute.

  This means it can no longer be accessed directly through @@logger, and that setting logger =
  on a subclass won't change the parent's logger.

  Jean Boussier

• Add .asc.nulls_first for all databases. Unfortunately MySQL still doesn't like nulls_last.

  Keenan Brock

• Improve performance of one? and many? by limiting the generated count query to 2 results.

  Gonzalo Riestra

• Don't check type when using if_not_exists on add_column.

  Previously, if a migration called add_column with the if_not_exists option set to true
  the column_exists? check would look for a column with the same name and type as the migration.

  Recently it was discovered that the type passed to the migration is not always the same type
  as the column after migration. For example a column set to :mediumblob in the migration will
  be casted to binary when calling column.type. Since there is no straightforward way to cast
  the type to the database type without running the migration, we opted to drop the type check from
  add_column. This means that migrations adding a duplicate column with a different type will no
  longer raise an error.

  Eileen M. Uchitelle

• Log a warning message when running SQLite in production.

  Using SQLite in production ENV is generally discouraged. SQLite is also the default adapter
  in a new Rails application.
  For the above reasons log a warning message when running SQLite in production.

  The warning can be disabled by setting config.active_record.sqlite3_production_warning=false.

  Jacopo Beschi

• Add option to disable joins for has_one associations.

  In a multiple database application, associations can't join across
  databases. When set, this option instructs Rails to generate 2 or
  more queries rather than generating joins for has_one associations.

  Set the option on a has one through association:

  class Person
    has_one :dog
    has_one :veterinarian, through: :dog, disable_joins: true
  end
  

  Then instead of generating join SQL, two queries are used for @person.veterinarian:

  SELECT "dogs"."id" FROM "dogs" WHERE "dogs"."person_id" = ?  [["person_id", 1]]
  SELECT "veterinarians".* FROM "veterinarians" WHERE "veterinarians"."dog_id" = ?  [["dog_id", 1]]
  

  Sarah Vessels, Eileen M. Uchitelle

• Arel::Visitors::Dot now renders a complete set of properties when visiting
  Arel::Nodes::SelectCore, SelectStatement, InsertStatement, UpdateStatement, and
  DeleteStatement, which fixes #42026. Previously, some properties were omitted.

  Mike Dalessio

• Arel::Visitors::Dot now supports Arel::Nodes::Bin, Case, CurrentRow, Distinct,
  DistinctOn, Else, Except, InfixOperation, Intersect, Lock, NotRegexp, Quoted,
  Regexp, UnaryOperation, Union, UnionAll, When, and With. Previously, these node
  types caused an exception to be raised by Arel::Visitors::Dot#accept.

  Mike Dalessio

• Optimize remove_columns to use a single SQL statement.

  remove_columns :my_table, :col_one, :col_two
  

  Now results in the following SQL:

  ALTER TABLE "my_table" DROP COLUMN "col_one", DROP COLUMN "col_two"
  

  Jon Dufresne

• Ensure has_one autosave association callbacks get called once.

  Change the has_one autosave callback to be non cyclic as well.
  By doing this the autosave callback are made more consistent for
  all 3 cases: has_many, has_one, and belongs_to.

  Petrik de Heus

• Add option to disable joins for associations.

  In a multiple database application, associations can't join across
  databases. When set, this option instructs Rails to generate 2 or
  more queries rather than generating joins for associations.

  Set the option on a has many through association:

  class Dog
    has_many :treats, through: :humans, disable_joins: true
    has_many :humans
  end
  

  Then instead of generating join SQL, two queries are used for @dog.treats:

  SELECT "humans"."id" FROM "humans" WHERE "humans"."dog_id" = ?  [["dog_id", 1]]
  SELECT "treats".* FROM "treats" WHERE "treats"."human_id" IN (?, ?, ?)  [["human_id", 1], ["human_id", 2], ["human_id", 3]]
  

  Eileen M. Uchitelle, Aaron Patterson, Lee Quarella

• Add setting for enumerating column names in SELECT statements.

  Adding a column to a PostgreSQL database, for example, while the application is running can
  change the result of wildcard SELECT * queries, which invalidates the result
  of cached prepared statements and raises a PreparedStatementCacheExpired error.

  When enabled, Active Record will avoid wildcards and always include column names
  in SELECT queries, which will return consistent results and avoid prepared
  statement errors.

  Before:

  Book.limit(5)
  # SELECT * FROM books LIMIT 5
  

  After:

  # config/application.rb
  module MyApp
    class Application < Rails::Application
      config.active_record.enumerate_columns_in_select_statements = true
    end
  end
  
  # or, configure per-model
  class Book < ApplicationRecord
    self.enumerate_columns_in_select_statements = true
  end
  

  Book.limit(5)
  # SELECT id, author_id, name, format, status, language, etc FROM books LIMIT 5
  

  Matt Duszynski

• Allow passing SQL as on_duplicate value to #upsert_all to make it possible to use raw SQL to update columns on conflict:

  Book.upsert_all(
    [{ id: 1, status: 1 }, { id: 2, status: 1 }],
    on_duplicate: Arel.sql("status = GREATEST(books.status, EXCLUDED.status)")
  )
  

  Vladimir Dementyev

• Allow passing SQL as returning statement to #upsert_all:

  Article.insert_all(
    [
      { title: "Article 1", slug: "article-1", published: false },
      { title: "Article 2", slug: "article-2", published: false }
    ],
    returning: Arel.sql("id, (xmax = '0') as inserted, name as new_name")
  )
  

  Vladimir Dementyev

• Deprecate legacy_connection_handling.

  Eileen M. Uchitelle

• Add attribute encryption support.

  Encrypted attributes are declared at the model level. These
  are regular Active Record attributes backed by a column with
  the same name. The system will transparently encrypt these
  attributes before saving them into the database and will
  decrypt them when retrieving their values.

  class Person < ApplicationRecord
    encrypts :name
    encrypts :email_address, deterministic: true
  end
  

  You can learn more in the Active Record Encryption
  guide.

  Jorge Manrubia

• Changed Arel predications contains and overlaps to use
  quoted_node so that PostgreSQL arrays are quoted properly.

  Bradley Priest

• Add mode argument to record level strict_loading!.

  This argument can be used when enabling strict loading for a single record
  to specify that we only want to raise on n plus one queries.

  developer.strict_loading!(mode: :n_plus_one_only)
  
  developer.projects.to_a # Does not raise
  developer.projects.first.client # Raises StrictLoadingViolationError
  

  Previously, enabling strict loading would cause any lazily loaded
  association to raise an error. Using n_plus_one_only mode allows us to
  lazily load belongs_to, has_many, and other associations that are fetched
  through a single query.

  Dinah Shi

• Fix Float::INFINITY assignment to datetime column with postgresql adapter.

  Before:

  # With this config
  ActiveRecord::Base.time_zone_aware_attributes = true
  
  # and the following schema:
  create_table "postgresql_infinities" do |t|
    t.datetime "datetime"
  end
  
  # This test fails
  record = PostgresqlInfinity.create!(datetime: Float::INFINITY)
  assert_equal Float::INFINITY, record.datetime # record.datetime gets nil
  

  After this commit, record.datetime gets Float::INFINITY as expected.

  Shunichi Ikegami

• Type cast enum values by the original attribute type.

  The notable thing about this change is that unknown labels will no longer match 0 on MySQL.

  class Book < ActiveRecord::Base
    enum :status, { proposed: 0, written: 1, published: 2 }
  end
  

  Before:

  # SELECT `books`.* FROM `books` WHERE `books`.`status` = 'prohibited' LIMIT 1
  Book.find_by(status: :prohibited)
  # => #<Book id: 1, status: "proposed", ...> (for mysql2 adapter)
  # => ActiveRecord::StatementInvalid: PG::InvalidTextRepresentation: ERROR:  invalid input syntax for type integer: "prohibited" (for postgresql adapter)
  # => nil (for sqlite3 adapter)
  

  After:

  # SELECT `books`.* FROM `books` WHERE `books`.`status` IS NULL LIMIT 1
  Book.find_by(status: :prohibited)
  # => nil (for all adapters)
  

  Ryuta Kamizono

• Fixtures for has_many :through associations now load timestamps on join tables.

  Given this fixture:

  ### monkeys.yml
  george:
    name: George the Monkey
    fruits: apple
  
  ### fruits.yml
  apple:
    name: apple
  

  If the join table (fruit_monkeys) contains created_at or updated_at columns,
  these will now be populated when loading the fixture. Previously, fixture loading
  would crash if these columns were required, and leave them as null otherwise.

  Alex Ghiculescu

• Allow applications to configure the thread pool for async queries.

  Some applications may want one thread pool per database whereas others want to use
  a single global thread pool for all queries. By default, Rails will set async_query_executor
  to nil which will not initialize any executor. If load_async is called and no executor
  has been configured, the query will be executed in the foreground.

  To create one thread pool for all database connections to use applications can set
  config.active_record.async_query_executor to :global_thread_pool and optionally define
  config.active_record.global_executor_concurrency. This defaults to 4. For applications that want
  to have a thread pool for each database connection, config.active_record.async_query_executor can
  be set to :multi_thread_pool. The configuration for each thread pool is set in the database
  configuration.

  Eileen M. Uchitelle

• Allow new syntax for enum to avoid leading _ from reserved options.

  Before:

  class Book < ActiveRecord::Base
    enum status: [ :proposed, :written ], _prefix: true, _scopes: false
    enum cover: [ :hard, :soft ], _suffix: true, _default: :hard
  end
  

  After:

  class Book < ActiveRecord::Base
    enum :status, [ :proposed, :written ], prefix: true, scopes: false
    enum :cover, [ :hard, :soft ], suffix: true, default: :hard
  end
  

  Ryuta Kamizono

• Add ActiveRecord::Relation#load_async.

  This method schedules the query to be performed asynchronously from a thread pool.

  If the result is accessed before a background thread had the opportunity to perform
  the query, it will be performed in the foreground.

  This is useful for queries that can be performed long enough before their result will be
  needed, or for controllers which need to perform several independent queries.

  def index
    @categories = Category.some_complex_scope.load_async
    @posts = Post.some_complex_scope.load_async
  end
  

  Active Record logs will also include timing info for the duration of how long
  the main thread had to wait to access the result. This timing is useful to know
  whether or not it's worth to load the query asynchronously.

  DEBUG -- :   Category Load (62.1ms)  SELECT * FROM `categories` LIMIT 50
  DEBUG -- :   ASYNC Post Load (64ms) (db time 126.1ms)  SELECT * FROM `posts` LIMIT 100
  

  The duration in the first set of parens is how long the main thread was blocked
  waiting for the results, and the second set of parens with "db time" is how long
  the entire query took to execute.

  Jean Boussier

• Implemented ActiveRecord::Relation#excluding method.

  This method excludes the specified record (or collection of records) from
  the resulting relation:

  Post.excluding(post)
  Post.excluding(post_one, post_two)
  

  Also works on associations:

  post.comments.excluding(comment)
  post.comments.excluding(comment_one, comment_two)
  

  This is short-hand for Post.where.not(id: post.id) (for a single record)
  and Post.where.not(id: [post_one.id, post_two.id]) (for a collection).

  Glen Crawford

• Skip optimised #exist? query when #include? is called on a relation
  with a having clause.

  Relations that have aliased select values AND a having clause that
  references an aliased select value would generate an error when
  #include? was called, due to an optimisation that would generate
  call #exists? on the relation instead, which effectively alters
  the select values of the query (and thus removes the aliased select
  values), but leaves the having clause intact. Because the having
  clause is then referencing an aliased column that is no longer
  present in the simplified query, an ActiveRecord::InvalidStatement
  error was raised.

  A sample query affected by this problem:

  Author.select('COUNT(*) as total_posts', 'authors.*')
        .joins(:posts)
        .group(:id)
        .having('total_posts > 2')
        .include?(Author.first)
  

  This change adds an addition check to the condition that skips the
  simplified #exists? query, which simply checks for the presence of
  a having clause.

  Fixes #41417.

  Michael Smart

• Increment postgres prepared statement counter before making a prepared statement, so if the statement is aborted
  without Rails knowledge (e.g., if app gets killed during long-running query or due to Rack::Timeout), app won't end
  up in perpetual crash state for being inconsistent with PostgreSQL.

  wbharding, Martin Tepper

• Add ability to apply scoping to all_queries.

  Some applications may want to use the scoping method but previously it only
  worked on certain types of queries. This change allows the scoping method to apply
  to all queries for a model in a block.

  Post.where(blog_id: post.blog_id).scoping(all_queries: true) do
    post.update(title: "a post title") # adds `posts.blog_id = 1` to the query
  end
  

  Eileen M. Uchitelle

• ActiveRecord::Calculations.calculate called with :average
  (aliased as ActiveRecord::Calculations.average) will now use column-based
  type casting. This means that floating-point number columns will now be
  aggregated as Float and decimal columns will be aggregated as BigDecimal.

  Integers are handled as a special case returning BigDecimal always
  (this was the case before already).

  # With the following schema:
  create_table "measurements" do |t|
    t.float "temperature"
  end
  
  # Before:
  Measurement.average(:temperature).class
  # => BigDecimal
  
  # After:
  Measurement.average(:temperature).class
  # => Float
  

  Before this change, Rails just called to_d on average aggregates from the
  database adapter. This is not the case anymore. If you relied on that kind
  of magic, you now need to register your own ActiveRecord::Type
  (see ActiveRecord::Attributes::ClassMethods for documentation).

  Josua Schmid

• PostgreSQL: introduce ActiveRecord::ConnectionAdapters::PostgreSQLAdapter.datetime_type.

  This setting controls what native type Active Record should use when you call datetime in
  a migration or schema. It takes a symbol which must correspond to one of the configured
  NATIVE_DATABASE_TYPES. The default is :timestamp, meaning t.datetime in a migration
  will create a "timestamp without time zone" column. To use "timestamp with time zone",
  change this to :timestamptz in an initializer.

  You should run bin/rails db:migrate to rebuild your schema.rb if you change this.

  Alex Ghiculescu

• PostgreSQL: handle timestamp with time zone columns correctly in schema.rb.

  Previously they dumped as t.datetime :column_name, now they dump as t.timestamptz :column_name,
  and are created as timestamptz columns when the schema is loaded.

  Alex Ghiculescu

• Removing trailing whitespace when matching columns in
  ActiveRecord::Sanitization.disallow_raw_sql!.

  Gannon McGibbon, Adrian Hirt

• Expose a way for applications to set a primary_abstract_class.

  Multiple database applications that use a primary abstract class that is not
  named ApplicationRecord can now set a specific class to be the primary_abstract_class.

  class PrimaryApplicationRecord
    self.primary_abstract_class

  When an application boots it automatically connects to the primary or first database in the
  database configuration file. In a multiple database application that then call connects_to
  needs to know that the default connection is the same as the ApplicationRecord connection.
  However, some applications have a differently named ApplicationRecord. This prevents Active
  Record from opening duplicate connections to the same database.

• Support hash config for structure_dump_flags and structure_load_flags flags.
  Now that Active Record supports multiple databases configuration,
  we need a way to pass specific flags for dump/load databases since
  the options are not the same for different adapters.
  We can use in the original way:

  ActiveRecord::Tasks::DatabaseTasks.structure_dump_flags = ['--no-defaults', '--skip-add-drop-table']
  # or
  ActiveRecord::Tasks::DatabaseTasks.structure_dump_flags = '--no-defaults --skip-add-drop-table'
  

  And also use it passing a hash, with one or more keys, where the key
  is the adapter

  ActiveRecord::Tasks::DatabaseTasks.structure_dump_flags = {
    mysql2: ['--no-defaults', '--skip-add-drop-table'],
    postgres: '--no-tablespaces'
  }
  

  Gustavo Gonzalez

• Connection specification now passes the "url" key as a configuration for the
  adapter if the "url" protocol is "jdbc", "http", or "https". Previously only
  urls with the "jdbc" prefix were passed to the Active Record Adapter, others
  are assumed to be adapter specification urls.

  Fixes #41137.

  Jonathan Bracy

• Allow to opt-out of strict_loading mode on a per-record base.

  This is useful when strict loading is enabled application wide or on a
  model level.

  class User < ApplicationRecord
    has_many :bookmarks
    has_many :articles, strict_loading: true
  end
  
  user = User.first
  user.articles                        # => ActiveRecord::StrictLoadingViolationError
  user.bookmarks                       # => #<ActiveRecord::Associations::CollectionProxy>
  
  user.strict_loading!(true)           # => true
  user.bookmarks                       # => ActiveRecord::StrictLoadingViolationError
  
  user.strict_loading!(false)          # => false
  user.bookmarks                       # => #<ActiveRecord::Associations::CollectionProxy>
  user.articles.strict_loading!(false) # => #<ActiveRecord::Associations::CollectionProxy>
  

  Ayrton De Craene

• Add FinderMethods#sole and #find_sole_by to find and assert the
  presence of exactly one record.

  Used when you need a single row, but also want to assert that there aren't
  multiple rows matching the condition; especially for when database
  constraints aren't enough or are impractical.

  Product.where(["price = %?", price]).sole
  # => ActiveRecord::RecordNotFound      (if no Product with given price)
  # => #<Product ...>                    (if one Product with given price)
  # => ActiveRecord::SoleRecordExceeded  (if more than one Product with given price)
  
  user.api_keys.find_sole_by(key: key)
  # as above
  

  Asherah Connor

• Makes ActiveRecord::AttributeMethods::Query respect the getter overrides defined in the model.

  Before:

  class User
    def admin
      false # Overriding the getter to always return false
    end
  end
  
  user = User.first
  user.update(admin: true)
  
  user.admin # false (as expected, due to the getter overwrite)
  user.admin? # true (not expected, returned the DB column value)
  

  After this commit, user.admin? above returns false, as expected.

  Fixes #40771.

  Felipe

• Allow delegated_type to be specified primary_key and foreign_key.

  Since delegated_type assumes that the foreign_key ends with _id,
  singular_id defined by it does not work when the foreign_key does
  not end with id. This change fixes it by taking into account
  primary_key and foreign_key in the options.

  Ryota Egusa

• Expose an invert_where method that will invert all scope conditions.

  class User
    scope :active, -> { where(accepted: true, locked: false) }
  end
  
  User.active
  # ... WHERE `accepted` = 1 AND `locked` = 0
  
  User.active.invert_where
  # ... WHERE NOT (`accepted` = 1 AND `locked` = 0)
  

  Kevin Deisz

• Restore possibility of passing false to :polymorphic option of belongs_to.

  Previously, passing false would trigger the option validation logic
  to throw an error saying :polymorphic would not be a valid option.

  glaszig

• Remove deprecated database kwarg from connected_to.

  Eileen M. Uchitelle, John Crepezzi

• Allow adding nonnamed expression indexes to be revertible.

  Previously, the following code would raise an error, when executed while rolling back,
  and the index name should be specified explicitly. Now, the index name is inferred
  automatically.

  add_index(:items, "to_tsvector('english', description)")
  

  Fixes #40732.

  fatkodima

• Only warn about negative enums if a positive form that would cause conflicts exists.

  Fixes #39065.

  Alex Ghiculescu

• Add option to run default_scope on all queries.

  Previously, a default_scope would only run on select or insert queries. In some cases, like non-Rails tenant sharding solutions, it may be desirable to run default_scope on all queries in order to ensure queries are including a foreign key for the shard (i.e. blog_id).

  Now applications can add an option to run on all queries including select, insert, delete, and update by adding an all_queries option to the default scope definition.

  class Article < ApplicationRecord
    default_scope -> { where(blog_id: Current.blog.id) }, all_queries: true
  end
  

  Eileen M. Uchitelle

• Add where.associated to check for the presence of an association.

  # Before:
  account.users.joins(:contact).where.not(contact_id: nil)
  
  # After:
  account.users.where.associated(:contact)
  

  Also mirrors where.missing.

  Kasper Timm Hansen

• Support direct uploads to multiple services.

  Dmitry Tsepelev

• Invalid default content types are deprecated

  Blobs created with content_type image/jpg, image/pjpeg, image/bmp, text/javascript will now produce
  a deprecation warning, since these are not valid content types.

  These content types will be removed from the defaults in Rails 7.1.

  You can set config.active_storage.silence_invalid_content_types_warning = true to dismiss the warning.

  Santiago Bartesaghi

• Remove deprecated methods: build_after_upload, create_after_upload! in favor of create_and_upload!,
  and service_url in favor of url.

  Santiago Bartesaghi

• Add support of strict_loading_by_default to ActiveStorage::Representations controllers.

  Anton Topchii, Andrew White

• Allow to detach an attachment when record is not persisted.

  Jacopo Beschi

• Use libvips instead of ImageMagick to analyze images when active_storage.variant_processor = vips.

  Breno Gazzola

• Add metadata value for presence of video channel in video blobs.

  The metadata attribute of video blobs has a new boolean key named video that is set to
  true if the file has an video channel and false if it doesn't.

  Breno Gazzola

• Deprecate usage of purge and purge_later from the association extension.

  Jacopo Beschi

• Passing extra parameters in ActiveStorage::Blob#url to S3 Client.

  This allows calls of ActiveStorage::Blob#url to have more interaction with
  the S3 Presigner, enabling, amongst other options, custom S3 domain URL
  Generation.

  blob = ActiveStorage::Blob.last
  
  blob.url # => https://<bucket-name>.s3.<region>.amazonaws.com/<key>
  blob.url(virtual_host: true) # => # => https://<bucket-name>/<key>

• The parameters sent to ffmpeg for generating a video preview image are now
  configurable under config.active_storage.video_preview_arguments.

  Brendon Muir

• The ActiveStorage video previewer will now use scene change detection to generate
  better preview images (rather than the previous default of using the first frame
  of the video). This change requires FFmpeg v3.4+.

  Jonathan Hefner

• Add support for ActiveStorage expiring URLs.

  rails_blob_path(user.avatar, disposition: "attachment", expires_in: 30.minutes)
  
  <%= image_tag rails_blob_path(user.avatar.variant(resize: "100x100"), expires_in: 30.minutes) %>
  

  If you want to set default expiration time for ActiveStorage URLs throughout your application, set config.active_storage.urls_expire_in.

  aki77

• Allow to purge an attachment when record is not persisted for has_many_attached.

  Jacopo Beschi

• Add with_all_variant_records method to eager load all variant records on an attachment at once.
  with_attached_image scope now eager loads variant records if using variant tracking.

  Alex Ghiculescu

• Add metadata value for presence of audio channel in video blobs.

  The metadata attribute of video blobs has a new boolean key named audio that is set to
  true if the file has an audio channel and false if it doesn't.

  Breno Gazzola

• Adds analyzer for audio files.

  Breno Gazzola

• Respect Active Record's primary_key_type in Active Storage migrations.

  fatkodima

• Allow expires_in for ActiveStorage signed ids.

  aki77

• Allow to purge an attachment when record is not persisted for has_one_attached.

  Jacopo Beschi

• Add a load hook called active_storage_variant_record (providing ActiveStorage::VariantRecord)
  to allow for overriding aspects of the ActiveStorage::VariantRecord class. This makes
  ActiveStorage::VariantRecord consistent with ActiveStorage::Blob and ActiveStorage::Attachment
  that already have load hooks.

  Brendon Muir

• ActiveStorage::PreviewError is raised when a previewer is unable to generate a preview image.

  Alex Robbin

• Add ActiveStorage::Streaming module that can be included in a controller to get access to #send_blob_stream,
  which wraps the new ActionController::Base#send_stream method to stream a blob from cloud storage:

  class MyPublicBlobsController < ApplicationController
    include ActiveStorage::SetBlob, ActiveStorage::Streaming
  
    def show
      http_cache_forever(public: true) do
        send_blob_stream @blob, disposition: params[:disposition]
      end
    end
  end
  

  DHH

• Add ability to use pre-defined variants.

  class User < ActiveRecord::Base
    has_one_attached :avatar do |attachable|
      attachable.variant :thumb, resize: "100x100"
      attachable.variant :medium, resize: "300x300", monochrome: true
    end
  end
  
  class Gallery < ActiveRecord::Base
    has_many_attached :photos do |attachable|
      attachable.variant :thumb, resize: "100x100"
      attachable.variant :medium, resize: "300x300", monochrome: true
    end
  end
  
  <%= image_tag user.avatar.variant(:thumb) %>

• After setting config.active_storage.resolve_model_to_route = :rails_storage_proxy
rails_blob_path and rails_representation_path will generate proxy URLs by default.

  Ali Ismayilov

• Declare ActiveStorage::FixtureSet and ActiveStorage::FixtureSet.blob to
  improve fixture integration.

  Sean Doyle

Active Support

• Fix ActiveSupport::Duration.build to support negative values.

  The algorithm to collect the parts of the ActiveSupport::Duration
  ignored the sign of the value and accumulated incorrect part values. This
  impacted ActiveSupport::Duration#sum (which is dependent on parts) but
  not ActiveSupport::Duration#eql? (which is dependent on value).

  Caleb Buxton, Braden Staudacher

• Deprecate passing a format to #to_s in favor of #to_formatted_s in Array, Range, Date, DateTime, Time,
  BigDecimal, Float and, Integer.

  Rafael Mendonça França

• Document ActiveSupport::Testing::Deprecation.

  Sam Bostock & Sam Jordan

• Add Pathname#existence.

  Pathname.new("file").existence&.read
  

  Timo Schilling

• Remove deprecate ActiveSupport::Multibyte::Unicode.default_normalization_form.

  Rafael Mendonça França

• Remove deprecated support to use Range#include? to check the inclusion of a value in
  a date time range is deprecated.

  Rafael Mendonça França

• Remove deprecated URI.parser.

  Rafael Mendonça França

• Remove deprecated config.active_support.use_sha1_digests.

  Rafael Mendonça França

• Invoking Object#with_options without a &block argument returns the
  ActiveSupport::OptionMerger instance.

  Sean Doyle

• Rails.application.executor hooks can now be called around every test

  This helps to better simulate request or job local state being reset around tests and prevents state
  leaking from one test to another.

  However it requires the executor hooks executed in the test environment to be re-entrant.

  To enable this, set config.active_support.executor_around_test_case = true (this is the default in Rails 7).

  Jean Boussier

• ActiveSupport::DescendantsTracker now mostly delegate to Class#descendants on Ruby 3.1

  Ruby now provides a fast Class#descendants making ActiveSupport::DescendantsTracker mostly useless.

  As a result the following methods are deprecated:

  • ActiveSupport::DescendantsTracker.direct_descendants
  • ActiveSupport::DescendantsTracker#direct_descendants

  Jean Boussier

• Fix the Digest::UUID.uuid_from_hash behavior for namespace IDs that are different from the ones defined on Digest::UUID.

  The new behavior will be enabled by setting the
  config.active_support.use_rfc4122_namespaced_uuids option to true
  and is the default for new apps.

  The old behavior is the default for upgraded apps and will output a
  deprecation warning every time a value that is different than one of
  the constants defined on the Digest::UUID extension is used as the
  namespace ID.

  Alex Robbin, Erich Soares Machado, Eugene Kenny

• ActiveSupport::Inflector::Inflections#clear(:acronyms) is now supported,
  and inflector.clear / inflector.clear(:all) also clears acronyms.

  Alex Ghiculescu, Oliver Peate

• ActiveSupport::Dependencies no longer installs a const_missing hook. Before this, you could push to the autoload paths and have constants autoloaded. This feature, known as the classic autoloader, has been removed.

  Xavier Noria

• Private internal classes of ActiveSupport::Dependencies have been deleted, like ActiveSupport::Dependencies::Reference, ActiveSupport::Dependencies::Blamable, and others.

  Xavier Noria

• The private API of ActiveSupport::Dependencies has been deleted. That includes methods like hook!, unhook!, depend_on, require_or_load, mechanism, and many others.

  Xavier Noria

• Improves the performance of ActiveSupport::NumberHelper formatters by avoiding the use of exceptions as flow control.

  Mike Dalessio

• Removed rescue block from ActiveSupport::Cache::RedisCacheStore#handle_exception

  Previously, if you provided a error_handler to redis_cache_store, any errors thrown by
  the error handler would be rescued and logged only. Removed the rescue clause from handle_exception
  to allow these to be thrown.

  Nicholas A. Stuart

• Allow entirely opting out of deprecation warnings.

  Previously if you did app.config.active_support.deprecation = :silence, some work would
  still be done on each call to ActiveSupport::Deprecation.warn. In very hot paths, this could
  cause performance issues.

  Now, you can make ActiveSupport::Deprecation.warn a no-op:

  config.active_support.report_deprecations = false
  

  This is the default in production for new apps. It is the equivalent to:

  config.active_support.deprecation = :silence
  config.active_support.disallowed_deprecation = :silence
  

  but will take a more optimised code path.

  Alex Ghiculescu

• Faster tests by parallelizing only when overhead is justified by the number
  of them.

  Running tests in parallel adds overhead in terms of database
  setup and fixture loading. Now, Rails will only parallelize test executions when
  there are enough tests to make it worth it.

  This threshold is 50 by default, and is configurable via config setting in
  your test.rb:

  config.active_support.test_parallelization_threshold = 100
  

  It's also configurable at the test case level:

  class ActiveSupport::TestCase
    parallelize threshold: 100
  end
  

  Jorge Manrubia

• OpenSSL constants are now used for Digest computations.

  Dirkjan Bussink

• TimeZone.iso8601 now accepts valid ordinal values similar to Ruby's Date._iso8601 method.
  A valid ordinal value will be converted to an instance of TimeWithZone using the :year
  and :yday fragments returned from Date._iso8601.

  twz = ActiveSupport::TimeZone["Eastern Time (US & Canada)"].iso8601("21087")
  twz.to_a[0, 6] == [0, 0, 0, 28, 03, 2021]
  

  Steve Laing

• Time#change and methods that call it (e.g. Time#advance) will now
  return a Time with the timezone argument provided, if the caller was
  initialized with a timezone argument.

  Fixes #42467.

  Alex Ghiculescu

• Allow serializing any module or class to JSON by name.

  Tyler Rick, Zachary Scott

• Raise ActiveSupport::EncryptedFile::MissingKeyError when the
  RAILS_MASTER_KEY environment variable is blank (e.g. "").

  Sunny Ripert

• The from: option is added to ActiveSupport::TestCase#assert_no_changes.

  It permits asserting on the initial value that is expected not to change.

  assert_no_changes -> { Status.all_good? }, from: true do
    post :create, params: { status: { ok: true } }
  end
  

  George Claghorn

• Deprecate ActiveSupport::SafeBuffer's incorrect implicit conversion of objects into string.

  Except for a few methods like String#%, objects must implement #to_str
  to be implicitly converted to a String in string operations. In some
  circumstances ActiveSupport::SafeBuffer was incorrectly calling the
  explicit conversion method (#to_s) on them. This behavior is now
  deprecated.

  Jean Boussier

• Allow nested access to keys on Rails.application.credentials.

  Previously only top level keys in credentials.yml.enc could be accessed with method calls. Now any key can.

  For example, given these secrets:

  aws:
    access_key_id: 123
    secret_access_key: 345
  

  Rails.application.credentials.aws.access_key_id will now return the same thing as
  Rails.application.credentials.aws[:access_key_id].

  Alex Ghiculescu

• Added a faster and more compact ActiveSupport::Cache serialization format.

  It can be enabled with config.active_support.cache_format_version = 7.0 or
  config.load_defaults 7.0. Regardless of the configuration Active Support
  7.0 can read cache entries serialized by Active Support 6.1 which allows to
  upgrade without invalidating the cache. However Rails 6.1 can't read the
  new format, so all readers must be upgraded before the new format is enabled.

  Jean Boussier

• Add Enumerable#sole, per ActiveRecord::FinderMethods#sole. Returns the
  sole item of the enumerable, raising if no items are found, or if more than
  one is.

  Asherah Connor

• Freeze ActiveSupport::Duration#parts and remove writer methods.

  Durations are meant to be value objects and should not be mutated.

  Andrew White

• Fix ActiveSupport::TimeZone#utc_to_local with fractional seconds.

  When utc_to_local_returns_utc_offset_times is false and the time
  instance had fractional seconds the new UTC time instance was out by
  a factor of 1,000,000 as the Time.utc constructor takes a usec
  value and not a fractional second value.

  Andrew White

• Add expires_at argument to ActiveSupport::Cache write and fetch to set a cache entry TTL as an absolute time.

  Rails.cache.write(key, value, expires_at: Time.now.at_end_of_hour)
  

  Jean Boussier

• Deprecate ActiveSupport::TimeWithZone.name so that from Rails 7.1 it will use the default implementation.

  Andrew White

• Deprecates Rails custom Enumerable#sum and Array#sum in favor of Ruby's native implementation which
  is considerably faster.

  Ruby requires an initializer for non-numeric type as per examples below:

  %w[foo bar].sum('')
  # instead of %w[foo bar].sum
  
  [[1, 2], [3, 4, 5]].sum([])
  # instead of [[1, 2], [3, 4, 5]].sum
  

  Alberto Mota

• Tests parallelization is now disabled when running individual files to prevent the setup overhead.

  It can still be enforced if the environment variable PARALLEL_WORKERS is present and set to a value greater than 1.

  Ricardo Díaz

• Fix proxying keyword arguments in ActiveSupport::CurrentAttributes.

  Marcin Kołodziej

• Add Enumerable#maximum and Enumerable#minimum to easily calculate the maximum or minimum from extracted
  elements of an enumerable.

  payments = [Payment.new(5), Payment.new(15), Payment.new(10)]
  
  payments.minimum(:price) # => 5
  payments.maximum(:price) # => 15
  

  This also allows passing enumerables to fresh_when and stale? in Action Controller.
  See PR #41404 for an example.

  Ayrton De Craene

• ActiveSupport::Cache::MemCacheStore now accepts an explicit nil for its addresses argument.

  config.cache_store = :mem_cache_store, nil
  
  # is now equivalent to
  
  config.cache_store = :mem_cache_store
  
  # and is also equivalent to
  
  config.cache_store = :mem_cache_store, ENV["MEMCACHE_SERVERS"] || "localhost:11211"
  
  # which is the fallback behavior of Dalli
  

  This helps those migrating from :dalli_store, where an explicit nil was permitted.

  Michael Overmeyer

• Add Enumerable#in_order_of to put an Enumerable in a certain order by a key.

  DHH

• ActiveSupport::Inflector.camelize behaves expected when provided a symbol :upper or :lower argument. Matches
  String#camelize behavior.

• Change default X-XSS-Protection header to disable XSS auditor

  This header has been deprecated and the XSS auditor it triggered
  has been removed from all major modern browsers (in favour of
  Content Security Policy) that implemented this header to begin with
  (Firefox never did).

  OWASP
  suggests setting this header to '0' to disable the default behaviour
  on old browsers as it can introduce additional security issues.

  Added the new behaviour as a framework default from Rails 7.0.

  Linas Juškevičius

• The setter config.autoloader= has been deleted. zeitwerk is the only
  available autoloading mode.

  Xavier Noria

• config.autoload_once_paths can be configured in the body of the
  application class defined in config/application.rb or in the configuration
  for environments in config/environments/*.

  Similarly, engines can configure that collection in the class body of the
  engine class or in the configuration for environments.

  After that, the collection is frozen, and you can autoload from those paths.
  They are managed by the Rails.autoloaders.once autoloader, which does not
  reload, only autoloads/eager loads.

  Xavier Noria

• During initialization, you cannot autoload reloadable classes or modules
  like application models, unless they are wrapped in a to_prepare block.
  For example, from config/initializers/*, or in application, engines, or
  railties initializers.

  Please check the autoloading
  guide
  for details.

  Xavier Noria

• While they are allowed to have elements in common, it is no longer required
  that config.autoload_once_paths is a subset of config.autoload_paths.
  The former are managed by the once autoloader. The main autoloader
  manages the latter minus the former.

  Xavier Noria

• Show Rake task description if command is run with -h.

  Alex Ghiculescu

• Change default branch for new Rails projects and plugins to main.

  Prateek Choudhary

• The new method Rails.benchmark gives you a quick way to measure and log the execution time taken by a block:

  def test_expensive_stuff
    Rails.benchmark("test_expensive_stuff") { ... }
  end
  

  This functionality was available in some contexts only before.

  Simon Perepelitsa

• Applications generated with --skip-sprockets no longer get app/assets/config/manifest.js and app/assets/stylesheets/application.css.

  Cindy Gao

• Add support for stylesheets and ERB views to rails stats.

  Joel Hawksley

• Allow appended root routes to take precedence over internal welcome controller.

Active Support

• Deprecate passing a format to #to_s in favor of #to_formatted_s in Array, Range, Date, DateTime, Time,
  BigDecimal, Float and, Integer.

  Rafael Mendonça França

• Document ActiveSupport::Testing::Deprecation.

  Sam Bostock & Sam Jordan

• Add Pathname#existence.

  Pathname.new("file").existence&.read
  

  Timo Schilling

• Remove deprecate ActiveSupport::Multibyte::Unicode.default_normalization_form.

  Rafael Mendonça França

• Remove deprecated support to use Range#include? to check the inclusion of a value in
  a date time range is deprecated.

  Rafael Mendonça França

• Remove deprecated URI.parser.

  Rafael Mendonça França

• Remove deprecated config.active_support.use_sha1_digests.

  Rafael Mendonça França

• Invoking Object#with_options without a &block argument returns the
  ActiveSupport::OptionMerger instance.

  Sean Doyle

• Rails.application.executor hooks can now be called around every test

  This helps to better simulate request or job local state being reset around tests and prevents state
  leaking from one test to another.

  However it requires the executor hooks executed in the test environment to be re-entrant.

  To enable this, set config.active_support.executor_around_test_case = true (this is the default in Rails 7).

  Jean Boussier

• ActiveSupport::DescendantsTracker now mostly delegate to Class#descendants on Ruby 3.1

  Ruby now provides a fast Class#descendants making ActiveSupport::DescendantsTracker mostly useless.

  As a result the following methods are deprecated:

  • ActiveSupport::DescendantsTracker.direct_descendants
  • ActiveSupport::DescendantsTracker#direct_descendants

  Jean Boussier

• Fix the Digest::UUID.uuid_from_hash behavior for namespace IDs that are different from the ones defined on Digest::UUID.

  The new behavior will be enabled by setting the
  config.active_support.use_rfc4122_namespaced_uuids option to true
  and is the default for new apps.

  The old behavior is the default for upgraded apps and will output a
  deprecation warning every time a value that is different than one of
  the constants defined on the Digest::UUID extension is used as the
  namespace ID.

  Alex Robbin, Erich Soares Machado, Eugene Kenny

• ActiveSupport::Inflector::Inflections#clear(:acronyms) is now supported,
  and inflector.clear / inflector.clear(:all) also clears acronyms.

  Alex Ghiculescu, Oliver Peate

Active Model

• Remove support to Marshal load Rails 5.x ActiveModel::AttributeSet format.

  Rafael Mendonça França

• Remove support to Marshal and YAML load Rails 5.x error format.

  Rafael Mendonça França

• Remove deprecated support to use []= in ActiveModel::Errors#messages.

  Rafael Mendonça França

• Remove deprecated support to delete errors from ActiveModel::Errors#messages.

  Rafael Mendonça França

• Remove deprecated support to clear errors from ActiveModel::Errors#messages.

  Rafael Mendonça França

• Remove deprecated support concat errors to ActiveModel::Errors#messages.

  Rafael Mendonça França

• Remove deprecated ActiveModel::Errors#to_xml.

  Rafael Mendonça França

  Rafael Mendonça França

• Remove deprecated ActiveModel::Errors#values.

  Rafael Mendonça França

  Rafael Mendonça França

• Remove deprecated ActiveModel::Errors#to_h.

  Rafael Mendonça França

• Remove deprecated enumeration of ActiveModel::Errors instances as a Hash.

  Rafael Mendonça França

• Clear secure password cache if password is set to nil

  Before:

  user.password = 'something'
  user.password = nil

  user.password # => 'something'

  Now:

  user.password = 'something'
  user.password = nil

  user.password # => nil

  Markus Doits

Active Record

• Remove deprecated ActiveRecord::DatabaseConfigurations::DatabaseConfig#spec_name.

  Rafael Mendonça França

• Remove deprecated ActiveRecord::Connection#in_clause_length.

  Rafael Mendonça França

• Remove deprecated ActiveRecord::Connection#allowed_index_name_length.

  Rafael Mendonça França

• Remove deprecated ActiveRecord::Base#remove_connection.

  Rafael Mendonça França

• Load STI Models in fixtures

  Data from Fixtures now loads based on the specific class for models with
  Single Table Inheritance. This affects enums defined in subclasses, previously
  the value of these fields was not parsed and remained nil

  Andres Howard

• #authenticate returns false when the password is blank instead of raising an error.

  Muhammad Muhammad Ibrahim

• Fix ActiveRecord::QueryMethods#in_order_of behavior for integer enums.

  ActiveRecord::QueryMethods#in_order_of didn't work as expected for enums stored as integers in the database when passing an array of strings or symbols as the order argument. This unexpected behavior occurred because the string or symbol values were not casted to match the integers in the database.

  The following example now works as expected:

  class Book < ApplicationRecord
    enum status: [:proposed, :written, :published]
  end
  
  Book.in_order_of(:status, %w[written published proposed])
  

  Alexandre Ruban

• Ignore persisted in-memory records when merging target lists.

  Kevin Sjöberg

• Add a new option :update_only to upsert_all to configure the list of columns to update in case of conflict.

  Before, you could only customize the update SQL sentence via :on_duplicate. There is now a new option :update_only that lets you provide a list of columns to update in case of conflict:

  Commodity.upsert_all(
    [
      { id: 2, name: "Copper", price: 4.84 },
      { id: 4, name: "Gold", price: 1380.87 },
      { id: 6, name: "Aluminium", price: 0.35 }
    ],
    update_only: [:price] # Only prices will be updated
  )
  

  Jorge Manrubia

• Remove deprecated ActiveRecord::Result#map! and ActiveRecord::Result#collect!.

  Rafael Mendonça França

• Remove deprecated ActiveRecord::Base.configurations.to_h.

  Rafael Mendonça França

• Remove deprecated ActiveRecord::Base.configurations.default_hash.

  Rafael Mendonça França

• Remove deprecated ActiveRecord::Base.arel_attribute.

  Rafael Mendonça França

• Remove deprecated ActiveRecord::Base.connection_config.

  Rafael Mendonça França

• Filter attributes in SQL logs

  Previously, SQL queries in logs containing ActiveRecord::Base.filter_attributes were not filtered.

  Now, the filter attributes will be masked [FILTERED] in the logs when prepared_statement is enabled.

  # Before:
    Foo Load (0.2ms)  SELECT "foos".* FROM "foos" WHERE "foos"."passw" = ? LIMIT ?  [["passw", "hello"], ["LIMIT", 1]]
  
  # After:
    Foo Load (0.5ms)  SELECT "foos".* FROM "foos" WHERE "foos"."passw" = ? LIMIT ?  [["passw", "[FILTERED]"], ["LIMIT", 1]]
  

  Aishwarya Subramanian

• Remove deprecated Tasks::DatabaseTasks.spec.

  Rafael Mendonça França

• Remove deprecated Tasks::DatabaseTasks.current_config.

  Rafael Mendonça França

• Deprecate Tasks::DatabaseTasks.schema_file_type.

  Rafael Mendonça França

• Remove deprecated Tasks::DatabaseTasks.dump_filename.

  Rafael Mendonça França

• Remove deprecated Tasks::DatabaseTasks.schema_file.

  Rafael Mendonça França

• Remove deprecated environment and name arguments from Tasks::DatabaseTasks.schema_up_to_date?.

  Rafael Mendonça França

• Merging conditions on the same column no longer maintain both conditions,
  and will be consistently replaced by the latter condition.

  # Rails 6.1 (IN clause is replaced by merger side equality condition)
  Author.where(id: [david.id, mary.id]).merge(Author.where(id: bob)) # => [bob]
  # Rails 6.1 (both conflict conditions exists, deprecated)
  Author.where(id: david.id..mary.id).merge(Author.where(id: bob)) # => []
  # Rails 6.1 with rewhere to migrate to Rails 7.0's behavior
  Author.where(id: david.id..mary.id).merge(Author.where(id: bob), rewhere: true) # => [bob]
  # Rails 7.0 (same behavior with IN clause, mergee side condition is consistently replaced)
  Author.where(id: [david.id, mary.id]).merge(Author.where(id: bob)) # => [bob]
  Author.where(id: david.id..mary.id).merge(Author.where(id: bob)) # => [bob]
  
  *Rafael Mendonça França*
  
  

• Remove deprecated support to Model.reorder(nil).first to search using non-deterministic order.

  Rafael Mendonça França

• Remove deprecated rake tasks:

  • db:schema:load_if_ruby
  • db:structure:dump
  • db:structure:load
  • db:structure:load_if_sql
  • db:structure:dump:#{name}
  • db:structure:load:#{name}
  • db:test:load_structure
  • db:test:load_structure:#{name}

  Rafael Mendonça França

• Remove deprecated DatabaseConfig#config method.

  Rafael Mendonça França

• Rollback transactions when the block returns earlier than expected.

  Before this change, when a transaction block returned early, the transaction would be committed.

  The problem is that timeouts triggered inside the transaction block was also making the incomplete transaction
  to be committed, so in order to avoid this mistake, the transaction block is rolled back.

  Rafael Mendonça França

• Add middleware for automatic shard swapping.

  Provides a basic middleware to perform automatic shard swapping. Applications will provide a resolver which will determine for an individual request which shard should be used. Example:

  config.active_record.shard_resolver = ->(request) {
    subdomain = request.subdomain
    tenant = Tenant.find_by_subdomain!(subdomain)
    tenant.shard
  }
  

  See guides for more details.

  Eileen M. Uchitelle, John Crepezzi

• Remove deprecated support to pass a column to type_cast.

  Rafael Mendonça França

• Remove deprecated support to type cast to database values ActiveRecord::Base objects.

  Rafael Mendonça França

• Remove deprecated support to quote ActiveRecord::Base objects.

  Rafael Mendonça França

• Remove deprecacated support to resolve connection using "primary" as connection specification name.

  Rafael Mendonça França

• Remove deprecation warning when using :interval column is used in PostgreSQL database.

  Now, interval columns will return ActiveSupport::Duration objects instead of strings.

  To keep the old behavior, you can add this line to your model:

  attribute :column, :string
  

  Rafael Mendonça França

• Remove deprecated support to YAML load ActiveRecord::Base instance in the Rails 4.2 and 4.1 formats.

  Rafael Mendonça França

• Remove deprecated option :spec_name in the configs_for method.

  Rafael Mendonça França

• Remove deprecated ActiveRecord::Base.allow_unsafe_raw_sql.

  Rafael Mendonça França

• Fix regression bug that caused ignoring additional conditions for preloading has_many-through relations.

  Fixes #43132

  Alexander Pauly

• Fix has_many inversing recursion on models with recursive associations.

  Gannon McGibbon

• Add accepts_nested_attributes_for support for delegated_type

  class Entry < ApplicationRecord
    delegated_type :entryable, types: %w[ Message Comment ]
    accepts_nested_attributes_for :entryable
  end
  
  entry = Entry.create(entryable_type: 'Message', entryable_attributes: { content: 'Hello world' })
  # => #<Entry:0x00>
  # id: 1
  # entryable_id: 1,
  # entryable_type: 'Message'
  # ...>
  
  entry.entryable
  # => #<Message:0x01>
  # id: 1
  # content: 'Hello world'
  # ...>
  

  Previously it would raise an error:

  Entry.create(entryable_type: 'Message', entryable_attributes: { content: 'Hello world' })
  # ArgumentError: Cannot build association `entryable'. Are you trying to build a polymorphic one-to-one association?
  

  Sjors Baltus

• Use subquery for DELETE with GROUP_BY and HAVING clauses.

  Prior to this change, deletes with GROUP_BY and HAVING were returning an error.

  After this change, GROUP_BY and HAVING are valid clauses in DELETE queries, generating the following query:

  DELETE FROM "posts" WHERE "posts"."id" IN (
      SELECT "posts"."id" FROM "posts" INNER JOIN "comments" ON "comments"."post_id" = "posts"."id" GROUP BY "posts"."id" HAVING (count(comments.id) >= 2))
  )  [["flagged", "t"]]
  

  Ignacio Chiazzo Cardarello

• Use subquery for UPDATE with GROUP_BY and HAVING clauses.

  Prior to this change, updates with GROUP_BY and HAVING were being ignored, generating a SQL like this:

  UPDATE "posts" SET "flagged" = ? WHERE "posts"."id" IN (
      SELECT "posts"."id" FROM "posts" INNER JOIN "comments" ON "comments"."post_id" = "posts"."id"
  )  [["flagged", "t"]]
  

  After this change, GROUP_BY and HAVING clauses are used as a subquery in updates, like this:

  UPDATE "posts" SET "flagged" = ? WHERE "posts"."id" IN (
      SELECT "posts"."id" FROM "posts" INNER JOIN "comments" ON "comments"."post_id" = "posts"."id"
      GROUP BY posts.id HAVING (count(comments.id) >= 2)
  )  [["flagged", "t"]]
  

  Ignacio Chiazzo Cardarello

• Add support for setting the filename of the schema or structure dump in the database config.

  Applications may now set their the filename or path of the schema / structure dump file in their database configuration.

  production:
    primary:
      database: my_db
      schema_dump: my_schema_dump_filename.rb
    animals:
      database: animals_db
      schema_dump: false
  

  The filename set in schema_dump will be used by the application. If set to false the schema will not be dumped. The database tasks are responsible for adding the database directory to the filename. If a full path is provided, the Rails tasks will use that instead of ActiveRecord::DatabaseTasks.db_dir.

  Eileen M. Uchitelle, Ryan Kerr

• Add ActiveRecord::Base.prohibit_shard_swapping to prevent attempts to change the shard within a block.

  John Crepezzi, Eileen M. Uchitelle

• Filter unchanged attributes with default function from insert query when partial_inserts is disabled.

  Akshay Birajdar, Jacopo Beschi

• Add support for FILTER clause (SQL:2003) to Arel.

  Currently supported by PostgreSQL 9.4+ and SQLite 3.30+.

  Andrey Novikov

• Automatically set timestamps on record creation during bulk insert/upsert

  Prior to this change, only updates during an upsert operation (e.g. upsert_all) would touch timestamps (updated_{at,on}). Now, record creations also touch timestamp columns ({created,updated}_{at,on}).

  This behaviour is controlled by the <model>.record_timestamps config, matching the behaviour of create, update, etc. It can also be overridden by using the record_timestamps: keyword argument.

  Note that this means upsert_all on models with record_timestamps = false will no longer touch updated_{at,on} automatically.

  Sam Bostock

• Don't require role when passing shard to connected_to.

  connected_to can now be called with a shard only. Note that role is still inherited if connected_to calls are nested.

  Eileen M. Uchitelle

• Add option to lazily load the schema cache on the connection.

  Previously, the only way to load the schema cache in Active Record was through the Railtie on boot. This option provides the ability to load the schema cache on the connection after it's been established. Loading the cache lazily on the connection can be beneficial for Rails applications that use multiple databases because it will load the cache at the time the connection is established. Currently Railties doesn't have access to the connections before boot.

  To use the cache, set config.active_record.lazily_load_schema_cache = true in your application configuration. In addition a schema_cache_path should be set in your database configuration if you don't want to use the default "db/schema_cache.yml" path.

  Eileen M. Uchitelle

• Allow automatic inverse_of detection for associations with scopes.

  Automatic inverse_of detection now works for associations with scopes. For
  example, the comments association here now automatically detects
  inverse_of: :post, so we don't need to pass that option:

  class Post < ActiveRecord::Base
    has_many :comments, -> { visible }
  end
  
  class Comment < ActiveRecord::Base
    belongs_to :post
  end
  

  Note that the automatic detection still won't work if the inverse
  association has a scope. In this example a scope on the post association
  would still prevent Rails from finding the inverse for the comments
  association.

  This will be the default for new apps in Rails 7. To opt in:

  config.active_record.automatic_scope_inversing = true
  

  Daniel Colson, Chris Bloom

• Accept optional transaction args to ActiveRecord::Locking::Pessimistic#with_lock

  #with_lock now accepts transaction options like requires_new:,
  isolation:, and joinable:

• Adds support for deferrable foreign key constraints in PostgreSQL.

  By default, foreign key constraints in PostgreSQL are checked after each statement. This works for most use cases,
  but becomes a major limitation when creating related records before the parent record is inserted into the database.
  One example of this is looking up / creating a person via one or more unique alias.

  Person.transaction do
    alias = Alias
      .create_with(user_id: SecureRandom.uuid)
      .create_or_find_by(name: "DHH")
  
    person = Person
      .create_with(name: "David Heinemeier Hansson")
      .create_or_find_by(id: alias.user_id)
  end
  

  Using the default behavior, the transaction would fail when executing the first INSERT statement.

  By passing the :deferrable option to the add_foreign_key statement in migrations, it's possible to defer this
  check.

  add_foreign_key :aliases, :person, deferrable: true
  

  Passing deferrable: true doesn't change the default behavior, but allows manually deferring the check using
  SET CONSTRAINTS ALL DEFERRED within a transaction. This will cause the foreign keys to be checked after the
  transaction.

  It's also possible to adjust the default behavior from an immediate check (after the statement), to a deferred check
  (after the transaction):

  add_foreign_key :aliases, :person, deferrable: :deferred
  

  Benedikt Deicke

• Allow configuring Postgres password through the socket URL.

  For example:

  ActiveRecord::DatabaseConfigurations::UrlConfig.new(
    :production, :production, 'postgres:///?user=user&password=secret&dbname=app', {}
  ).configuration_hash
  

  will now return,

  { :user=>"user", :password=>"secret", :dbname=>"app", :adapter=>"postgresql" }
  

  Abeid Ahmed

• PostgreSQL: support custom enum types

  In migrations, use create_enum to add a new enum type, and t.enum to add a column.

  def up
    create_enum :mood, ["happy", "sad"]
  
    change_table :cats do |t|
      t.enum :current_mood, enum_type: "mood", default: "happy", null: false
    end
  end
  

  Enums will be presented correctly in schema.rb. Note that this is only supported by
  the PostgreSQL adapter.

  Alex Ghiculescu

• Avoid COMMENT statements in PostgreSQL structure dumps

  COMMENT statements are now omitted from the output of db:structure:dump when using PostgreSQL >= 11.
  This allows loading the dump without a pgsql superuser account.

  Fixes #36816, #43107.

  Janosch Müller

• Add support for generated columns in PostgreSQL adapter

  Generated columns are supported since version 12.0 of PostgreSQL. This adds
  support of those to the PostgreSQL adapter.

  create_table :users do |t|
    t.string :name
    t.virtual :name_upcased, type: :string, as: 'upper(name)', stored: true
  end
  

  Michał Begejowicz

Action View

• Support fields model: [@nested, @model] the same way as form_with model: [@nested, @model].

  Sean Doyle

• Infer HTTP verb [method] from a model or Array with model as the first
  argument to button_to when combined with a block:

  button_to(Workshop.find(1)){ "Update" }
  #=> <form method="post" action="/workshops/1" class="button_to">
  #=>   <input type="hidden" name="_method" value="patch" autocomplete="off" />
  #=>   <button type="submit">Update</button>
  #=> </form>
  
  button_to([ Workshop.find(1), Session.find(1) ]) { "Update" }
  #=> <form method="post" action="/workshops/1/sessions/1" class="button_to">
  #=>   <input type="hidden" name="_method" value="patch" autocomplete="off" />
  #=>   <button type="submit">Update</button>
  #=> </form>
  

  Sean Doyle

• Support passing a Symbol as the first argument to FormBuilder#button:

  form.button(:draft, value: true)
  # => <button name="post[draft]" value="true" type="submit">Create post</button>
  
  form.button(:draft, value: true) do
    content_tag(:strong, "Save as draft")
  end
  # =>  <button name="post[draft]" value="true" type="submit">
  #       <strong>Save as draft</strong>
  #     </button>
  

  Sean Doyle

• Introduce the field_name view helper, along with the
  FormBuilder#field_name counterpart:

  form_for @post do |f|
    f.field_tag :tag, name: f.field_name(:tag, multiple: true)
    # => <input type="text" name="post[tag][]">
  end
  

  Sean Doyle

• Execute the ActionView::Base.field_error_proc within the context of the
  ActionView::Base instance:

  config.action_view.field_error_proc = proc { |html| content_tag(:div, html, class: "field_with_errors") }
  

  Sean Doyle

• Add support for button_to ..., authenticity_token: false

  button_to "Create", Post.new, authenticity_token: false
  # => <form class="button_to" method="post" action="/posts"><button type="submit">Create</button></form>
  
  button_to "Create", Post.new, authenticity_token: true
  # => <form class="button_to" method="post" action="/posts"><button type="submit">Create</button><input type="hidden" name="form_token" value="abc123..." autocomplete="off" /></form>
  
  button_to "Create", Post.new, authenticity_token: "secret"
  # => <form class="button_to" method="post" action="/posts"><button type="submit">Create</button><input type="hidden" name="form_token" value="secret" autocomplete="off" /></form>
  

  Sean Doyle

• Support rendering <form> elements without [action] attributes by:

  • form_with url: false or form_with ..., html: { action: false }
  • form_for ..., url: false or form_for ..., html: { action: false }
  • form_tag false or form_tag ..., action: false
  • button_to "...", false or button_to(false) { ... }

  Sean Doyle

• Add :day_format option to date_select

  date_select("article", "written_on", day_format: ->(day) { day.ordinalize })

• Allow link_to helper to infer link name from Model#to_s when it
  is used with a single argument:

  link_to @profile
  #=> <a href="/profiles/1">Eileen</a>
  

  This assumes the model class implements a to_s method like this:

  class Profile < ApplicationRecord
    # ...
    def to_s
      name
    end
  end
  

  Previously you had to supply a second argument even if the Profile
  model implemented a #to_s method that called the name method.

  link_to @profile, @profile.name
  #=> <a href="/profiles/1">Eileen</a>

  # => <svg><use href="#cool-icon"></svg>

Action Pack

• Rails.application.executor hooks can now be called around every request in a ActionController::TestCase

  This helps to better simulate request or job local state being reset between requests and prevent state
  leaking from one request to another.

  To enable this, set config.active_support.executor_around_test_case = true (this is the default in Rails 7).

• Raise ActionController::Redirecting::UnsafeRedirectError for unsafe redirect_to redirects.

  This allows rescue_from to be used to add a default fallback route:

  rescue_from ActionController::Redirecting::UnsafeRedirectError do
    redirect_to root_url
  end
  

  Kasper Timm Hansen, Chris Oliver

• Add url_from to verify a redirect location is internal.

  Takes the open redirect protection from redirect_to so users can wrap a
  param, and fall back to an alternate redirect URL when the param provided
  one is unsafe.

  def create
    redirect_to url_from(params[:redirect_url]) || root_url
  end

• Allow Capybara driver name overrides in SystemTestCase::driven_by

  Allow users to prevent conflicts among drivers that use the same driver
  type (selenium, poltergeist, webkit, rack test).

  Fixes #42502

• Allow multiline to be passed in routes when using wildcard segments.

  Previously routes with newlines weren't detected when using wildcard segments, returning
  a No route matches error.
  After this change, routes with newlines are detected on wildcard segments. Example

    draw do
      get "/wildcard/*wildcard_segment", to: SimpleApp.new("foo#index"), as: :wildcard
    end
  
    # After the change, the path matches.
    assert_equal "/wildcard/a%0Anewline", url_helpers.wildcard_path(wildcard_segment: "a\nnewline")
  

  Fixes #39103

• Treat html suffix in controller translation.

• Allow permitting numeric params.

  Previously it was impossible to permit different fields on numeric parameters.
  After this change you can specify different fields for each numbered parameter.
  For example params like,

  book: {
          authors_attributes: {
            '0': { name: "William Shakespeare", age_of_death: "52" },
            '1': { name: "Unattributed Assistant" },
            '2': "Not a hash",
            'new_record': { name: "Some name" }
          }
        }
  

  Before you could permit name on each author with,
  permit book: { authors_attributes: [ :name ] }

  After this change you can permit different keys on each numbered element,
  permit book: { authors_attributes: { '1': [ :name ], '0': [ :name, :age_of_death ] } }

  Fixes #41625

• Update HostAuthorization middleware to render debug info only
  when config.consider_all_requests_local is set to true.

  Also, blocked host info is always logged with level error.

  Fixes #42813

• Add Server-Timing middleware

  Server-Timing specification defines how the server can communicate to browsers performance metrics
  about the request it is responding to.

  The ServerTiming middleware is enabled by default on development environment by default using the
  config.server_timing setting and set the relevant duration metrics in the Server-Timing header

  The full specification for Server-Timing header can be found in: https://www.w3.org/TR/server-timing/#dfn-server-timing-header-field

Action Cable

• The Action Cable client now ensures successful channel subscriptions:

  • The client maintains a set of pending subscriptions until either
    the server confirms the subscription or the channel is torn down.
  • Rectifies the race condition where an unsubscribe is rapidly followed
    by a subscribe (on the same channel identifier) and the requests are
    handled out of order by the ActionCable server, thereby ignoring the
    subscribe command.

  Daniel Spinosa

Active Storage

• Add ActiveStorage::Blob.compose to concatenate multiple blobs.

  Gannon McGibbon

• Setting custom metadata on blobs are now persisted to remote storage.

  joshuamsager

• Support direct uploads to multiple services.

  Dmitry Tsepelev

• Invalid default content types are deprecated

  Blobs created with content_type image/jpg, image/pjpeg, image/bmp, text/javascript will now produce
  a deprecation warning, since these are not valid content types.

  These content types will be removed from the defaults in Rails 7.1.

  You can set config.active_storage.silence_invalid_content_types_warning = true to dismiss the warning.

Action Mailbox

• Change default X-XSS-Protection header to disable XSS auditor

  This header has been deprecated and the XSS auditor it triggered
  has been removed from all major modern browsers (in favour of
  Content Security Policy) that implemented this header to begin with
  (Firefox never did).

  OWASP
  suggests setting this header to '0' to disable the default behaviour
  on old browsers as it can introduce additional security issues.

  Added the new behaviour as a framework default from Rails 7.0.

  Christian Sutter

• Scaffolds now use date_field, time_field and datetime_field instead of
  date_select, time_select and datetime_select; thus providing native date/time pickers.

  Martijn Lafeber

• Fix a regression in which autoload paths were initialized too late.
