CHANGELOG - rails 7.2.2.1 documentation

`Rails` 7.2.2.1 (December 10, 2024)¶ ↑

No changes.

`Rails` 7.2.2 (October 30, 2024)¶ ↑

Fix support for query_cache: false in database.yml.

query_cache: false would no longer entirely disable the Active Record query cache.

zzak
Set .attributes_for_inspect to :all by default.

For new applications it is set to [:id] in config/environment/production.rb.

In the console all the attributes are always shown.

Andrew Novoselac
PG::UnableToSend: no connection to the server is now retryable as a connection-related exception

Kazuma Watanabe
Fix marshalling of unsaved associated records in 7.1 format.

The 7.1 format would only marshal associated records if the association was loaded. But associations that would only contain unsaved records would be skipped.

Jean Boussier
Fix incorrect SQL query when passing an empty hash to ActiveRecord::Base.insert.

David Stosik
Allow to save records with polymorphic join tables that have inverse_of specified.

Markus Doits
Fix association scopes applying on the incorrect join when using a polymorphic has_many through:.

Joshua Young

Fix dependent: :destroy for bi-directional has one through association.

Fixes #50948.

class Left < ActiveRecord::Base
  has_one :middle, dependent: :destroy
  has_one :right, through: :middle
end

class Middle < ActiveRecord::Base
  belongs_to :left, dependent: :destroy
  belongs_to :right, dependent: :destroy
end

class Right < ActiveRecord::Base
  has_one :middle, dependent: :destroy
  has_one :left, through: :middle
end

In the above example left.destroy wouldn't destroy its associated Right record.

Andy Stewart

Properly handle lazily pinned connection pools.

Fixes #53147.

When using transactional fixtures with system tests to similar tools such as capybara, it could happen that a connection end up pinned by the server thread rather than the test thread, causing "Cannot expire connection, it is owned by a different thread" errors.

Jean Boussier

Fix ActiveRecord::Base.with to accept more than two sub queries.

Fixes #53110.

User.with(foo: [User.select(:id), User.select(:id), User.select(:id)]).to_sql
undefined method `union' for an instance of Arel::Nodes::UnionAll (NoMethodError)

The above now works as expected.

fatkodima

Properly release pinned connections with non joinable connections.

Fixes #52973

When running system tests with transactional fixtures on, it could happen that the connection leased by the Puma thread wouldn't be properly released back to the pool, causing "Cannot expire connection, it is owned by a different thread" errors in later tests.

Jean Boussier
Make Float distinguish between float4 and float8 in PostgreSQL.

Fixes #52742

Ryota Kitazawa, Takayuki Nagatomi
Fix an issue where .left_outer_joins used with multiple associations that have the same child association but different parents does not join all parents.

Previously, using .left_outer_joins with the same child association would only join one of the parents.

Now it will correctly join both parents.

Fixes #41498.

Garrett Blehm
Ensure ActiveRecord::Encryption.config is always ready before access.

Previously, ActiveRecord::Encryption configuration was deferred until ActiveRecord::Base was loaded. Therefore, accessing ActiveRecord::Encryption.config properties before ActiveRecord::Base was loaded would give incorrect results.

ActiveRecord::Encryption now has its own loading hook so that its configuration is set as soon as needed.

When ActiveRecord::Base is loaded, even lazily, it in turn triggers the loading of ActiveRecord::Encryption, thus preserving the original behavior of having its config ready before any use of ActiveRecord::Base.

Maxime Réty
Add TimeZoneConverter#== method, so objects will be properly compared by their type, scale, limit & precision.

Address #52699.

Ruy Rocha

`Rails` 7.2.1.2 (October 23, 2024)¶ ↑

No changes.

`Rails` 7.2.1.1 (October 15, 2024)¶ ↑

No changes.

`Rails` 7.2.1 (August 22, 2024)¶ ↑

Fix detection for enum columns with parallelized tests and PostgreSQL.

Rafael Mendonça França
Allow to eager load nested nil associations.

fatkodima
Fix swallowing ignore order warning when batching using BatchEnumerator.

fatkodima
Fix memory bloat on the connection pool when using the Fiber IsolatedExecutionState.

Jean Boussier
Restore inferred association class with the same modularized name.

Justin Ko
Fix ActiveRecord::Base.inspect to properly explain how to load schema information.

Jean Boussier
Check invalid enum options for the new syntax.

The options using _ prefix in the old syntax are invalid in the new syntax.

Rafael Mendonça França
Fix ActiveRecord::Encryption::EncryptedAttributeType#type to return actual cast type.

Vasiliy Ermolovich
Fix create_table with :auto_increment option for MySQL adapter.

fatkodima

`Rails` 7.2.0 (August 09, 2024)¶ ↑

Handle commas in Sqlite3 default function definitions.

Stephen Margheim
Fixes validates_associated raising an exception when configured with a singular association and having index_nested_attribute_errors enabled.

Martin Spickermann
The constant ActiveRecord::ImmutableRelation has been deprecated because we want to reserve that name for a stronger sense of "immutable relation". Please use ActiveRecord::UnmodifiableRelation instead.

Xavier Noria
Add condensed inspect for ConnectionPool, AbstractAdapter, and DatabaseConfig.

Hartley McGuire
Fixed a memory performance issue in Active Record attribute methods definition.

Jean Boussier
Define the new Active Support notification event start_transaction.active_record.

This event is fired when database transactions or savepoints start, and complements transaction.active_record, which is emitted when they finish.

The payload has the transaction (:transaction) and the connection (:connection).

Xavier Noria
Fix an issue where the IDs reader method did not return expected results for preloaded associations in models using composite primary keys.

Jay Ang
The payload of sql.active_record Active Support notifications now has the current transaction in the :transaction key.

Xavier Noria
The payload of transaction.active_record Active Support notifications now has the transaction the event is related to in the :transaction key.

Xavier Noria
Define ActiveRecord::Transaction#uuid, which returns a UUID for the database transaction. This may be helpful when tracing database activity. These UUIDs are generated only on demand.

Xavier Noria
Fix inference of association model on nested models with the same demodularized name.

E.g. with the following setup:
```
class Nested::Post < ApplicationRecord
  has_one :post, through: :other
end
```
Before, post would infer the model as Nested::Post, but now it correctly infers Post.

Joshua Young
PostgreSQL Cidr#change? detects the address prefix change.

Taketo Takashima
Change BatchEnumerator#destroy_all to return the total number of affected rows.

Previously, it always returned nil.

fatkodima
Support touch_all in batches.
```
Post.in_batches.touch_all
```
fatkodima
Add support for :if_not_exists and :force options to create_schema.

fatkodima
Fix index_errors having incorrect index in association validation errors.

lulalala
Add index_errors: :nested_attributes_order mode.

This indexes the association validation errors based on the order received by nested attributes setter, and respects the reject_if configuration. This enables API to provide enough information to the frontend to map the validation errors back to their respective form fields.

lulalala
Add Rails.application.config.active_record.postgresql_adapter_decode_dates to opt out of decoding dates automatically with the postgresql adapter. Defaults to true.

Joé Dupuis
Association option query_constraints is deprecated in favor of foreign_key.

Nikita Vasilevsky
Add ENV["SKIP_TEST_DATABASE_TRUNCATE"] flag to speed up multi-process test runs on large DBs when all tests run within default transaction.

This cuts ~10s from the test run of HEY when run by 24 processes against the 178 tables, since ~4,000 table truncates can then be skipped.

DHH

Added support for recursive common table expressions.

Post.with_recursive(
  post_and_replies: [
    Post.where(id: 42),
    Post.joins('JOIN post_and_replies ON posts.in_reply_to_id = post_and_replies.id'),
  ]
)

Generates the following SQL:

WITH RECURSIVE "post_and_replies" AS (
  (SELECT "posts".* FROM "posts" WHERE "posts"."id" = 42)
  UNION ALL
  (SELECT "posts".* FROM "posts" JOIN post_and_replies ON posts.in_reply_to_id = post_and_replies.id)
)
SELECT "posts".* FROM "posts"

ClearlyClaire

validate_constraint can be called in a change_table block.

ex:

change_table :products do |t|
  t.check_constraint "price > discounted_price", name: "price_check", validate: false
  t.validate_check_constraint "price_check"
end

Cody Cutrer

PostgreSQLAdapter now decodes columns of type date to Date instead of string.

Ex:

ActiveRecord::Base.connection
     .select_value("select '2024-01-01'::date").class #=> Date

Joé Dupuis

Strict loading using :n_plus_one_only does not eagerly load child associations.

With this change, child associations are no longer eagerly loaded, to match intended behavior and to prevent non-deterministic order issues caused by calling methods like first or last. As first and last don't cause an N+1 by themselves, calling child associations will no longer raise. Fixes #49473.

Before:

person = Person.find(1)
person.strict_loading!(mode: :n_plus_one_only)
person.posts.first
# SELECT * FROM posts WHERE person_id = 1; -- non-deterministic order
person.posts.first.firm # raises ActiveRecord::StrictLoadingViolationError

After:

person = Person.find(1)
person.strict_loading!(mode: :n_plus_one_only)
person.posts.first # this is 1+1, not N+1
# SELECT * FROM posts WHERE person_id = 1 ORDER BY id LIMIT 1;
person.posts.first.firm # no longer raises

Reid Lynch

Allow Sqlite3Adapter to use sqlite3 gem version 2.x.

Mike Dalessio

Allow ActiveRecord::Base#pluck to accept hash values.

# Before
Post.joins(:comments).pluck("posts.id", "comments.id", "comments.body")

# After
Post.joins(:comments).pluck(posts: [:id], comments: [:id, :body])

fatkodima

Raise an ActiveRecord::ActiveRecordError error when the MySQL database returns an invalid version string.

Kevin McPhillips

ActiveRecord::Base.transaction now yields an ActiveRecord::Transaction object.

This allows to register callbacks on it.

Article.transaction do |transaction|
  article.update(published: true)
  transaction.after_commit do
    PublishNotificationMailer.with(article: article).deliver_later
  end
end

Jean Boussier

Add ActiveRecord::Base.current_transaction.

Returns the current transaction, to allow registering callbacks on it.
```
Article.current_transaction.after_commit do
  PublishNotificationMailer.with(article: article).deliver_later
end
```
Jean Boussier
Add ActiveRecord.after_all_transactions_commit callback.

Useful for code that may run either inside or outside a transaction and needs to perform work after the state changes have been properly persisted.
```
def publish_article(article)
  article.update(published: true)
  ActiveRecord.after_all_transactions_commit do
    PublishNotificationMailer.with(article: article).deliver_later
  end
end
```
In the above example, the block is either executed immediately if called outside of a transaction, or called after the open transaction is committed.

If the transaction is rolled back, the block isn't called.

Jean Boussier
Add the ability to ignore counter cache columns until they are backfilled.

Starting to use counter caches on existing large tables can be troublesome, because the column values must be backfilled separately of the column addition (to not lock the table for too long) and before the use of :counter_cache (otherwise methods like size/any?/etc, which use counter caches internally, can produce incorrect results). People usually use database triggers or callbacks on child associations while backfilling before introducing a counter cache configuration to the association.

Now, to safely backfill the column, while keeping the column updated with child records added/removed, use:
```
class Comment < ApplicationRecord
  belongs_to :post, counter_cache: { active: false }
end
```
While the counter cache is not "active", the methods like size/any?/etc will not use it, but get the results directly from the database. After the counter cache column is backfilled, simply remove the { active: false } part from the counter cache definition, and it will now be used by the mentioned methods.

fatkodima
Retry known idempotent SELECT queries on connection-related exceptions.

SELECT queries we construct by walking the Arel tree and / or with known model attributes are idempotent and can safely be retried in the case of a connection error. Previously, adapters such as TrilogyAdapter would raise ActiveRecord::ConnectionFailed: Trilogy::EOFError when encountering a connection error mid-request.

Adrianna Chang
Allow association's foreign_key to be composite.

query_constraints option was the only way to configure a composite foreign key by passing an Array. Now it’s possible to pass an Array value as foreign_key to achieve the same behavior of an association.

Nikita Vasilevsky
Allow association's primary_key to be composite.

Association's primary_key can be composite when derived from associated model primary_key or query_constraints. Now it's possible to explicitly set it as composite on the association.

Nikita Vasilevsky
Add config.active_record.permanent_connection_checkout setting.

Controls whether ActiveRecord::Base.connection raises an error, emits a deprecation warning, or neither.

ActiveRecord::Base.connection checkouts a database connection from the pool and keeps it leased until the end of the request or job. This behavior can be undesirable in environments that use many more threads or fibers than there is available connections.

This configuration can be used to track down and eliminate code that calls ActiveRecord::Base.connection and migrate it to use ActiveRecord::Base.with_connection instead.

The default behavior remains unchanged, and there is currently no plans to change the default.

Jean Boussier
Add dirties option to uncached.

This adds a dirties option to ActiveRecord::Base.uncached and ActiveRecord::ConnectionAdapters::ConnectionPool#uncached.

When set to true (the default), writes will clear all query caches belonging to the current thread. When set to false, writes to the affected connection pool will not clear any query cache.

This is needed by Solid Cache so that cache writes do not clear query caches.

Donal McBreen
Deprecate ActiveRecord::Base.connection in favor of .lease_connection.

The method has been renamed as lease_connection to better reflect that the returned connection will be held for the duration of the request or job.

This deprecation is a soft deprecation, no warnings will be issued and there is no current plan to remove the method.

Jean Boussier
Deprecate ActiveRecord::ConnectionAdapters::ConnectionPool#connection.

The method has been renamed as lease_connection to better reflect that the returned connection will be held for the duration of the request or job.

Jean Boussier

Expose a generic fixture accessor for fixture names that may conflict with Minitest.

assert_equal "Ruby on Rails", web_sites(:rubyonrails).name
assert_equal "Ruby on Rails", fixture(:web_sites, :rubyonrails).name

Jean Boussier

Using Model.query_constraints with a single non-primary-key column used to raise as expected, but with an incorrect error message.

This has been fixed to raise with a more appropriate error message.

Joshua Young
Fix has_one association autosave setting the foreign key attribute when it is unchanged.

This behavior is also inconsistent with autosaving belongs_to and can have unintended side effects like raising an ActiveRecord::ReadonlyAttributeError when the foreign key attribute is marked as read-only.

Joshua Young
Remove deprecated behavior that would rollback a transaction block when exited using return, break or throw.

Rafael Mendonça França
Deprecate Rails.application.config.active_record.commit_transaction_on_non_local_return.

Rafael Mendonça França
Remove deprecated support to pass rewhere to ActiveRecord::Relation#merge.

Rafael Mendonça França
Remove deprecated support to pass deferrable: true to add_foreign_key.

Rafael Mendonça França
Remove deprecated support to quote ActiveSupport::Duration.

Rafael Mendonça França
Remove deprecated quote_bound_value.

Rafael Mendonça França
Remove deprecated ActiveRecord::ConnectionAdapters::ConnectionPool#connection_klass.

Rafael Mendonça França
Remove deprecated support to apply connection_pool_list, active_connections?, clear_active_connections!, clear_reloadable_connections!, clear_all_connections! and flush_idle_connections! to the connections pools for the current role when the role argument isn’t provided.

Rafael Mendonça França
Remove deprecated all_connection_pools.

Rafael Mendonça França
Remove deprecated ActiveRecord::ConnectionAdapters::SchemaCache#data_sources.

Rafael Mendonça França
Remove deprecated ActiveRecord::ConnectionAdapters::SchemaCache.load_from.

Rafael Mendonça França
Remove deprecated all_foreign_keys_valid? from database adapters.

Rafael Mendonça França
Remove deprecated support to passing coder and class as second argument to serialize.

Rafael Mendonça França
Remove deprecated support to ActiveRecord::Base#read_attribute(:id) to return the custom primary key value.

Rafael Mendonça França
Remove deprecated TestFixtures.fixture_path.

Rafael Mendonça França
Remove deprecated behavior to support referring to a singular association by its plural name.

Rafael Mendonça França
Deprecate Rails.application.config.active_record.allow_deprecated_singular_associations_name.

Rafael Mendonça França
Remove deprecated support to passing SchemaMigration and InternalMetadata classes as arguments to ActiveRecord::MigrationContext.

Rafael Mendonça França
Remove deprecated ActiveRecord::Migration.check_pending! method.

Rafael Mendonça França
Remove deprecated ActiveRecord::LogSubscriber.runtime method.

Rafael Mendonça França
Remove deprecated ActiveRecord::LogSubscriber.runtime= method.

Rafael Mendonça França
Remove deprecated ActiveRecord::LogSubscriber.reset_runtime method.

Rafael Mendonça França
Remove deprecated support to define explain in the connection adapter with 2 arguments.

Rafael Mendonça França
Remove deprecated ActiveRecord::ActiveJobRequiredError.

Rafael Mendonça França
Remove deprecated ActiveRecord::Base.clear_active_connections!.

Rafael Mendonça França
Remove deprecated ActiveRecord::Base.clear_reloadable_connections!.

Rafael Mendonça França
Remove deprecated ActiveRecord::Base.clear_all_connections!.

Rafael Mendonça França
Remove deprecated ActiveRecord::Base.flush_idle_connections!.

Rafael Mendonça França
Remove deprecated name argument from ActiveRecord::Base.remove_connection.

Rafael Mendonça França
Remove deprecated support to call alias_attribute with non-existent attribute names.

Rafael Mendonça França
Remove deprecated Rails.application.config.active_record.suppress_multiple_database_warning.

Rafael Mendonça França
Add ActiveRecord::Encryption::MessagePackMessageSerializer.

Serialize data to the MessagePack format, for efficient storage in binary columns.

The binary encoding requires around 30% less space than the base64 encoding used by the default serializer.

Donal McBreen
Add support for encrypting binary columns.

Ensure encryption and decryption pass Type::Binary::Data around for binary data.

Previously encrypting binary columns with the ActiveRecord::Encryption::MessageSerializer incidentally worked for MySQL and SQLite, but not PostgreSQL.

Donal McBreen
Deprecated ENV["SCHEMA_CACHE"] in favor of schema_cache_path in the database configuration.

Rafael Mendonça França
Add ActiveRecord::Base.with_connection as a shortcut for leasing a connection for a short duration.

The leased connection is yielded, and for the duration of the block, any call to ActiveRecord::Base.connection will yield that same connection.

This is useful to perform a few database operations without causing a connection to be leased for the entire duration of the request or job.

Jean Boussier
Deprecate config.active_record.warn_on_records_fetched_greater_than now that sql.active_record notification includes :row_count field.

Jason Nochlin
The fix ensures that the association is joined using the appropriate join type (either inner join or left outer join) based on the existing joins in the scope.

This prevents unintentional overrides of existing join types and ensures consistency in the generated SQL queries.

Example:
```
# `associated` will use `LEFT JOIN` instead of using `JOIN`
Post.left_joins(:author).where.associated(:author)
```
Saleh Alhaddad
Fix an issue where ActiveRecord::Encryption configurations are not ready before the loading of Active Record models, when an application is eager loaded. As a result, encrypted attributes could be misconfigured in some cases.

Maxime Réty

Deprecate defining an enum with keyword arguments.

class Function > ApplicationRecord
  # BAD
  enum color: [:red, :blue],
       type: [:instance, :class]

  # GOOD
  enum :color, [:red, :blue]
  enum :type, [:instance, :class]
end

Hartley McGuire

Add config.active_record.validate_migration_timestamps option for validating migration timestamps.

When set, validates that the timestamp prefix for a migration is no more than a day ahead of the timestamp associated with the current time. This is designed to prevent migrations prefixes from being hand-edited to future timestamps, which impacts migration generation and other migration commands.

Adrianna Chang
Properly synchronize Mysql2Adapter#active? and TrilogyAdapter#active?.

As well as disconnect! and verify!.

This generally isn't a big problem as connections must not be shared between threads, but is required when running transactional tests or system tests and could lead to a SEGV.

Jean Boussier
Support :source_location tag option for query log tags.
```
config.active_record.query_log_tags << :source_location
```
Calculating the caller location is a costly operation and should be used primarily in development (note, there is also a config.active_record.verbose_query_logs that serves the same purpose) or occasionally on production for debugging purposes.

fatkodima
Add an option to ActiveRecord::Encryption::Encryptor to disable compression.

Allow compression to be disabled by setting compress: false
```
class User
    encrypts :name, encryptor: ActiveRecord::Encryption::Encryptor.new(compress: false)
  end
```
Donal McBreen
Deprecate passing strings to ActiveRecord::Tasks::DatabaseTasks.cache_dump_filename.

A ActiveRecord::DatabaseConfigurations::DatabaseConfig object should be passed instead.

Rafael Mendonça França
Add row_count field to sql.active_record notification.

This field returns the amount of rows returned by the query that emitted the notification.

This metric is useful in cases where one wants to detect queries with big result sets.

Marvin Bitterlich
Consistently raise an ArgumentError when passing an invalid argument to a nested attributes association writer.

Previously, this would only raise on collection associations and produce a generic error on singular associations.

Now, it will raise on both collection and singular associations.

Joshua Young
Fix single quote escapes on default generated MySQL columns.

MySQL 5.7.5+ supports generated columns, which can be used to create a column that is computed from an expression.

Previously, the schema dump would output a string with double escapes for generated columns with single quotes in the default expression.

This would result in issues when importing the schema on a fresh instance of a MySQL database.

Now, the string will not be escaped and will be valid Ruby upon importing of the schema.

Yash Kapadia
Fix Migrations with versions older than 7.1 validating options given to add_reference and t.references.

Hartley McGuire
Add <role>_types class method to ActiveRecord::DelegatedType so that the delegated types can be introspected.

JP Rosevear
Make schema_dump, query_cache, replica and database_tasks configurable via DATABASE_URL.

This wouldn't always work previously because boolean values would be interpreted as strings.

e.g. DATABASE_URL=postgres://localhost/foo?schema_dump=false now properly disable dumping the schema cache.

Mike Coutermarsh, Jean Boussier
Introduce ActiveRecord::Transactions::ClassMethods#set_callback.

It is identical to ActiveSupport::Callbacks::ClassMethods#set_callback but with support for after_commit and after_rollback callback options.

Joshua Young
Make ActiveRecord::Encryption::Encryptor agnostic of the serialization format used for encrypted data.

Previously, the encryptor instance only allowed an encrypted value serialized as a String to be passed to the message serializer.

Now, the encryptor lets the configured message_serializer decide which types of serialized encrypted values are supported. A custom serialiser is therefore allowed to serialize ActiveRecord::Encryption::Message objects using a type other than String.

The default ActiveRecord::Encryption::MessageSerializer already ensures that only String objects are passed for deserialization.

Maxime Réty
Fix encrypted_attribute? to take into account context properties passed to encrypts.

Maxime Réty
The object returned by explain now responds to pluck, first, last, average, count, maximum, minimum, and sum. Those new methods run EXPLAIN on the corresponding queries:
```
User.all.explain.count
# EXPLAIN SELECT COUNT(*) FROM `users`
# ...

User.all.explain.maximum(:id)
# EXPLAIN SELECT MAX(`users`.`id`) FROM `users`
# ...
```
Petrik de Heus
Fixes an issue where validates_associated :on option wasn't respected when validating associated records.

Austen Madden, Alex Ghiculescu, Rafał Brize
Allow overriding SQLite defaults from database.yml.

Any PRAGMA configuration set under the pragmas key in the configuration file takes precedence over Rails' defaults, and additional PRAGMAs can be set as well.
```
database: storage/development.sqlite3
timeout: 5000
pragmas:
  journal_mode: off
  temp_store: memory
```
Stephen Margheim
Remove warning message when running SQLite in production, but leave it unconfigured.

There are valid use cases for running SQLite in production. However, it must be done with care, so instead of a warning most users won't see anyway, it's preferable to leave the configuration commented out to force them to think about having the database on a persistent volume etc.

Jacopo Beschi, Jean Boussier
Add support for generated columns to the SQLite3 adapter.

Generated columns (both stored and dynamic) are supported since version 3.31.0 of SQLite. This adds support for those to the SQLite3 adapter.
```
create_table :users do |t|
  t.string :name
  t.virtual :name_upper, type: :string, as: 'UPPER(name)'
  t.virtual :name_lower, type: :string, as: 'LOWER(name)', stored: true
end
```
Stephen Margheim
TrilogyAdapter: ignore host if socket parameter is set.

This allows to configure a connection on a UNIX socket via DATABASE_URL:
```
DATABASE_URL=trilogy://does-not-matter/my_db_production?socket=/var/run/mysql.sock
```
Jean Boussier
Make assert_queries_count, assert_no_queries, assert_queries_match, and assert_no_queries_match assertions public.

To assert the expected number of queries are made, Rails internally uses assert_queries_count and assert_no_queries. To assert that specific SQL queries are made, assert_queries_match and assert_no_queries_match are used. These assertions can now be used in applications as well.
```
class ArticleTest < ActiveSupport::TestCase
  test "queries are made" do
    assert_queries_count(1) { Article.first }
  end

  test "creates a foreign key" do
    assert_queries_match(/ADD FOREIGN KEY/i, include_schema: true) do
      @connection.add_foreign_key(:comments, :posts)
    end
  end
end
```
Petrik de Heus, fatkodima
Fix has_secure_token calls the setter method on initialize.

Abeid Ahmed
When using a DATABASE_URL, allow for a configuration to map the protocol in the URL to a specific database adapter. This allows decoupling the adapter the application chooses to use from the database connection details set in the deployment environment.
```
# ENV['DATABASE_URL'] = "mysql://localhost/example_database"
config.active_record.protocol_adapters.mysql = "trilogy"
# will connect to MySQL using the trilogy adapter
```
Jean Boussier, Kevin McPhillips
In cases where MySQL returns warning_count greater than zero, but returns no warnings when the SHOW WARNINGS query is executed, ActiveRecord.db_warnings_action proc will still be called with a generic warning message rather than silently ignoring the warning(s).

Kevin McPhillips
DatabaseConfigurations#configs_for accepts a symbol in the name parameter.

Andrew Novoselac
Fix where(field: values) queries when field is a serialized attribute (for example, when field uses ActiveRecord::Base.serialize or is a JSON column).

João Alves
Make the output of ActiveRecord::Core#inspect configurable.

By default, calling inspect on a record will yield a formatted string including just the id.
```
Post.first.inspect #=> "#<Post id: 1>"
```
The attributes to be included in the output of inspect can be configured with ActiveRecord::Core#attributes_for_inspect.
```
Post.attributes_for_inspect = [:id, :title]
Post.first.inspect #=> "#<Post id: 1, title: "Hello, World!">"
```
With attributes_for_inspect set to :all, inspect will list all the record's attributes.
```
Post.attributes_for_inspect = :all
Post.first.inspect #=> "#<Post id: 1, title: "Hello, World!", published_at: "2023-10-23 14:28:11 +0000">"
```
In development and test mode, attributes_for_inspect will be set to :all by default.

You can also call full_inspect to get an inspection with all the attributes.

The attributes in attribute_for_inspect will also be used for pretty_print.

Andrew Novoselac
Don't mark attributes as changed when reassigned to Float::INFINITY or -Float::INFINITY.

Maicol Bentancor
Support the RETURNING clause for MariaDB.

fatkodima, Nikolay Kondratyev
The SQLite3 adapter now implements the supports_deferrable_constraints? contract.

Allows foreign keys to be deferred by adding the :deferrable key to the foreign_key options.
```
add_reference :person, :alias, foreign_key: { deferrable: :deferred }
add_reference :alias, :person, foreign_key: { deferrable: :deferred }
```
Stephen Margheim

Add the set_constraints helper to PostgreSQL connections.

Post.create!(user_id: -1) # => ActiveRecord::InvalidForeignKey

Post.transaction do
  Post.connection.set_constraints(:deferred)
  p = Post.create!(user_id: -1)
  u = User.create!
  p.user = u
  p.save!
end

Cody Cutrer

Include ActiveModel::API in ActiveRecord::Base.

Sean Doyle
Ensure signed_id outputs url_safe strings.

Jason Meller
Add nulls_last and working desc.nulls_first for MySQL.

Tristan Fellows
Allow for more complex hash arguments for order which mimics where in ActiveRecord::Relation.
```
Topic.includes(:posts).order(posts: { created_at: :desc })
```
Myles Boone
