(possibly other cases too) + *Dana Sherson* - ``` - Post.where(id: 1).or(Post.where(id: 2)).where(foo: 3).unscope(where: :foo).to_sql - # Currently: - # SELECT "posts".* FROM "posts" WHERE ("posts"."id" = 2 OR "posts"."id" = 3) - # With fix: - # SELECT "posts".* FROM "posts" WHERE ("posts"."id" = 1 OR "posts"."id" = 2) - ``` +* Add `touch_all` method to `ActiveRecord::Relation`. - *Maxime Handfield Lapointe* + Example: -* Values constructed using multi-parameter assignment will now use the - post-type-cast value for rendering in single-field form inputs. + Person.where(name: "David").touch_all(time: Time.new(2020, 5, 16, 0, 0, 0)) - *Sean Griffin* + *fatkodima*, *duggiefresh* -* `Relation#joins` is no longer affected by the target model's - `current_scope`, with the exception of `unscoped`. +* Add `ActiveRecord::Base.base_class?` predicate. - Fixes #29338. + *Bogdan Gusiev* - *Sean Griffin* +* Add custom prefix option to ActiveRecord::Store.store_accessor. -* Change sqlite3 boolean serialization to use 1 and 0 + *Tan Huynh* - SQLite natively recognizes 1 and 0 as true and false, but does not natively - recognize 't' and 'f' as was previously serialized. +* Rails 6 requires Ruby 2.4.1 or newer. - This change in serialization requires a migration of stored boolean data - for SQLite databases, so it's implemented behind a configuration flag - whose default false value is deprecated. + *Jeremy Daer* - *Lisa Ugray* +* Deprecate `update_attributes`/`!` in favor of `update`/`!`. -* Skip query caching when working with batches of records (`find_each`, `find_in_batches`, - `in_batches`). + *Eddie Lebow* - Previously, records would be fetched in batches, but all records would be retained in memory - until the end of the request or job. - - *Eugene Kenny* - -* Prevent errors raised by `sql.active_record` notification subscribers from being converted into - `ActiveRecord::StatementInvalid` exceptions. - - *Dennis Taylor* - -* Fix eager loading/preloading association with scope including joins. - - Fixes #28324. - - *Ryuta Kamizono* - -* Fix transactions to apply state to child transactions - - Previously if you had a nested transaction and the outer transaction was rolledback the record from the - inner transaction would still be marked as persisted. - - This change fixes that by applying the state of the parent transaction to the child transaction when the - parent transaction is rolledback. This will correctly mark records from the inner transaction as not persisted. - - *Eileen M. Uchitelle*, *Aaron Patterson* - -* Deprecate `set_state` method in `TransactionState` - - Deprecated the `set_state` method in favor of setting the state via specific methods. If you need to mark the - state of the transaction you can now use `rollback!`, `commit!` or `nullify!` instead of - `set_state(:rolledback)`, `set_state(:committed)`, or `set_state(nil)`. - - *Eileen M. Uchitelle*, *Aaron Patterson* - -* Deprecate delegating to `arel` in `Relation`. - - *Ryuta Kamizono* - -* Fix eager loading to respect `store_full_sti_class` setting. - - *Ryuta Kamizono* - -* Query cache was unavailable when entering the `ActiveRecord::Base.cache` block - without being connected. - - *Tsukasa Oishi* - -* Previously, when building records using a `has_many :through` association, - if the child records were deleted before the parent was saved, they would - still be persisted. Now, if child records are deleted before the parent is saved - on a `has_many :through` association, the child records will not be persisted. - - *Tobias Kraze* - -* Merging two relations representing nested joins no longer transforms the joins of - the merged relation into LEFT OUTER JOIN. Example to clarify: - - ``` - Author.joins(:posts).merge(Post.joins(:comments)) - # Before the change: - #=> SELECT ... FROM authors INNER JOIN posts ON ... LEFT OUTER JOIN comments ON... - - # After the change: - #=> SELECT ... FROM authors INNER JOIN posts ON ... INNER JOIN comments ON... - ``` - - TODO: Add to the Rails 5.2 upgrade guide - - *Maxime Handfield Lapointe* - -* `ActiveRecord::Persistence#touch` does not work well when optimistic locking enabled and - `locking_column`, without default value, is null in the database. - - *bogdanvlviv* - -* Fix destroying existing object does not work well when optimistic locking enabled and - `locking_column` is null in the database. - - *bogdanvlviv* - -* Use bulk INSERT to insert fixtures for better performance. - - *Kir Shatrov* - -* Prevent making bind param if casted value is nil. - - *Ryuta Kamizono* - -* Deprecate passing arguments and block at the same time to `count` and `sum` in `ActiveRecord::Calculations`. - - *Ryuta Kamizono* - -* Loading model schema from database is now thread-safe. - - Fixes #28589. - - *Vikrant Chaudhary*, *David Abdemoulaie* - -* Add `ActiveRecord::Base#cache_version` to support recyclable cache keys via the new versioned entries - in `ActiveSupport::Cache`. This also means that `ActiveRecord::Base#cache_key` will now return a stable key - that does not include a timestamp any more. - - NOTE: This feature is turned off by default, and `#cache_key` will still return cache keys with timestamps - until you set `ActiveRecord::Base.cache_versioning = true`. That's the setting for all new apps on Rails 5.2+ +* Add ActiveRecord::Base.create_or_find_by/! to deal with the SELECT/INSERT race condition in + ActiveRecord::Base.find_or_create_by/! by leaning on unique constraints in the database. *DHH* -* Respect `SchemaDumper.ignore_tables` in rake tasks for databases structure dump - - *Rusty Geldmacher*, *Guillermo Iguaran* - -* Add type caster to `RuntimeReflection#alias_name` - - Fixes #28959. - - *Jon Moss* +* Add `Relation#pick` as short-hand for single-value plucks. -* Deprecate `supports_statement_cache?`. - - *Ryuta Kamizono* - -* Quote database name in `db:create` grant statement (when database user does not have access to create the database). - - *Rune Philosof* - -* Raise error `UnknownMigrationVersionError` on the movement of migrations - when the current migration does not exist. - - *bogdanvlviv* - -* Fix `bin/rails db:forward` first migration. - - *bogdanvlviv* - -* Support Descending Indexes for MySQL. - - MySQL 8.0.1 and higher supports descending indexes: `DESC` in an index definition is no longer ignored. - See https://dev.mysql.com/doc/refman/8.0/en/descending-indexes.html. - - *Ryuta Kamizono* - -* Fix inconsistency with changed attributes when overriding AR attribute reader. - - *bogdanvlviv* - -* When calling the dynamic fixture accessor method with no arguments it now returns all fixtures of this type. - Previously this method always returned an empty array. - - *Kevin McPhillips* + *DHH* -Please check [5-1-stable](https://github.com/rails/rails/blob/5-1-stable/activerecord/CHANGELOG.md) for previous changes. +Please check [5-2-stable](https://github.com/rails/rails/blob/5-2-stable/activerecord/CHANGELOG.md) for previous changes. |
