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

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"

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
orlast
. Asfirst
andlast
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

ActiveRecord::Base.transaction
now yields anActiveRecord::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.

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 likesize
/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

when encountering a connection error mid-request.Adrianna Chang

Allow association's
foreign_key

-
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 useActiveRecord::Base.with_connection
instead.The default behavior remains unchanged, and there is currently no plans to change the default.

Add dirties option to uncached.
This adds a

.When set to

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.

# `associated` will use `LEFT JOIN` instead of using `JOIN` Post.left_joins(:author).where.associated(:author)

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.

agnostic of the serialization format used for encrypted data.Previously, the encryptor instance only allowed an encrypted value serialized as a

objects using a type other thanString
.The default
ActiveRecord::Encryption::MessageSerializer
already ensures that onlyString
objects are passed for deserialization.Maxime Réty

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.
