Users can opt out of this by passing - `index: false`. - - Fixes #18146. - - *Matthew Draper*, *Prathamesh Sonpatki* - -* Run `type` attributes through attributes API type-casting before - instantiating the corresponding subclass. This makes it possible to define - custom STI mappings. - - Fixes #21986. - - *Yves Senn* - -* Don't try to quote functions or expressions passed to `:default` option if - they are passed as procs. - - This will generate proper query with the passed function or expression for - the default option, instead of trying to quote it in incorrect fashion. - - Example: - - create_table :posts do |t| - t.datetime :published_at, default: -> { 'NOW()' } - end - - *Ryuta Kamizono* - -* Fix regression when loading fixture files with symbol keys. - - Fixes #22584. - - *Yves Senn* - -* Use `version` column as primary key for schema_migrations table because - `schema_migrations` versions are guaranteed to be unique. - - This makes it possible to use `update_attributes` on models that do - not have a primary key. - - *Richard Schneeman* - -* Add short-hand methods for text and blob types in MySQL. - - In Pg and Sqlite3, `:text` and `:binary` have variable unlimited length. - But in MySQL, these have limited length for each types (ref #21591, #21619). - This change adds short-hand methods for each text and blob types. - - Example: - - create_table :foos do |t| - t.tinyblob :tiny_blob - t.mediumblob :medium_blob - t.longblob :long_blob - t.tinytext :tiny_text - t.mediumtext :medium_text - t.longtext :long_text - end - - *Ryuta Kamizono* - -* Take into account UTC offset when assigning string representation of - timestamp with offset specified to attribute of time type. - - *Andrey Novikov* - -* When calling `first` with a `limit` argument, return directly from the - `loaded?` records if available. - - *Ben Woosley* - -* Deprecate sending the `offset` argument to `find_nth`. Please use the - `offset` method on relation instead. - - *Ben Woosley* - -## Rails 5.0.0.beta1 (December 18, 2015) ## - -* Order the result of `find(ids)` to match the passed array, if the relation - has no explicit order defined. - - Fixes #20338. - - *Miguel Grazziotin*, *Matthew Draper* - -* Omit default limit values in dumped schema. It's tidier, and if the defaults - change in the future, we can address that via Migration API Versioning. - - *Jean Boussier* - -* Support passing the schema name as a prefix to table name in - `ConnectionAdapters::SchemaStatements#indexes`. Previously the prefix would - be considered a full part of the index name, and only the schema in the - current search path would be considered. - - *Grey Baker* - -* Ignore index name in `index_exists?` and `remove_index` when not passed a - name to check for. - - *Grey Baker* - -* Extract support for the legacy `mysql` database adapter from core. It will - live on in a separate gem for now, but most users should just use `mysql2`. - - *Abdelkader Boudih* - -* ApplicationRecord is a new superclass for all app models, analogous to app - controllers subclassing ApplicationController instead of - ActionController::Base. This gives apps a single spot to configure app-wide - model behavior. - - Newly generated applications have `app/models/application_record.rb` - present by default. - - *Genadi Samokovarov* - -* Version the API presented to migration classes, so we can change parameter - defaults without breaking existing migrations, or forcing them to be - rewritten through a deprecation cycle. - - New migrations specify the Rails version they were written for: - - class AddStatusToOrders < ActiveRecord::Migration[5.0] - def change - # ... - end - end - - *Matthew Draper*, *Ravil Bayramgalin* - -* Use bind params for `limit` and `offset`. This will generate significantly - fewer prepared statements for common tasks like pagination. To support this - change, passing a string containing a comma to `limit` has been deprecated, - and passing an Arel node to `limit` is no longer supported. - - Fixes #22250. - - *Sean Griffin* - -* Introduce after_{create,update,delete}_commit callbacks. - - Before: - - after_commit :add_to_index_later, on: :create - after_commit :update_in_index_later, on: :update - after_commit :remove_from_index_later, on: :destroy - - After: - - after_create_commit :add_to_index_later - after_update_commit :update_in_index_later - after_destroy_commit :remove_from_index_later - - Fixes #22515. - - *Genadi Samokovarov* - -* Respect the column default values for `inheritance_column` when - instantiating records through the base class. - - Fixes #17121. - - Example: - - # The schema of BaseModel has `t.string :type, default: 'SubType'` - subtype = BaseModel.new - assert_equals SubType, subtype.class - - *Kuldeep Aggarwal* - -* Fix `rake db:structure:dump` on Postgres when multiple schemas are used. - - Fixes #22346. - - *Nick Muerdter*, *ckoenig* - -* Add schema dumping support for PostgreSQL geometric data types. - - *Ryuta Kamizono* - -* Except keys of `build_record`'s argument from `create_scope` in `initialize_attributes`. - - Fixes #21893. - - *Yuichiro Kaneko* - -* Deprecate `connection.tables` on the SQLite3 and MySQL adapters. - Also deprecate passing arguments to `#tables`. - And deprecate `table_exists?`. - - The `#tables` method of some adapters (mysql, mysql2, sqlite3) would return - both tables and views while others (postgresql) just return tables. To make - their behavior consistent, `#tables` will return only tables in the future. - - The `#table_exists?` method would check both tables and views. To make - their behavior consistent with `#tables`, `#table_exists?` will check only - tables in the future. - - *Yuichiro Kaneko* - -* Improve support for non Active Record objects on `validates_associated` - - Skipping `marked_for_destruction?` when the associated object does not responds - to it make easier to validate virtual associations built on top of Active Model - objects and/or serialized objects that implement a `valid?` instance method. - - *Kassio Borges*, *Lucas Mazza* - -* Change connection management middleware to return a new response with - a body proxy, rather than mutating the original. - - *Kevin Buchanan* - -* Make `db:migrate:status` to render `1_some.rb` format migrate files. - - These files are in `db/migrate`: - - * 1_valid_people_have_last_names.rb - * 20150819202140_irreversible_migration.rb - * 20150823202140_add_admin_flag_to_users.rb - * 20150823202141_migration_tests.rb - * 2_we_need_reminders.rb - * 3_innocent_jointable.rb - - Before: - - $ bundle exec rake db:migrate:status - ... - - Status Migration ID Migration Name - -------------------------------------------------- - up 001 ********** NO FILE ********** - up 002 ********** NO FILE ********** - up 003 ********** NO FILE ********** - up 20150819202140 Irreversible migration - up 20150823202140 Add admin flag to users - up 20150823202141 Migration tests - - After: - - $ bundle exec rake db:migrate:status - ... - - Status Migration ID Migration Name - -------------------------------------------------- - up 001 Valid people have last names - up 002 We need reminders - up 003 Innocent jointable - up 20150819202140 Irreversible migration - up 20150823202140 Add admin flag to users - up 20150823202141 Migration tests - - *Yuichiro Kaneko* - -* Define `ActiveRecord::Sanitization.sanitize_sql_for_order` and use it inside - `preprocess_order_args`. - - *Yuichiro Kaneko* - -* Allow bigint with default nil for avoiding auto increment primary key. - - *Ryuta Kamizono* - -* Remove `DEFAULT_CHARSET` and `DEFAULT_COLLATION` in `MySQLDatabaseTasks`. - - We should omit the collation entirely rather than providing a default. - Then the choice is the responsibility of the server and MySQL distribution. - - *Ryuta Kamizono* - -* Alias `ActiveRecord::Relation#left_joins` to - `ActiveRecord::Relation#left_outer_joins`. - - *Takashi Kokubun* - -* Use advisory locking to raise a `ConcurrentMigrationError` instead of - attempting to migrate when another migration is currently running. - - *Sam Davies* - -* Added `ActiveRecord::Relation#left_outer_joins`. - - Example: - - User.left_outer_joins(:posts) - # => SELECT "users".* FROM "users" LEFT OUTER JOIN "posts" ON - "posts"."user_id" = "users"."id" - - *Florian Thomas* - -* Support passing an array to `order` for SQL parameter sanitization. - - *Aaron Suggs* - -* Avoid disabling errors on the PostgreSQL connection when enabling the - `standard_conforming_strings` setting. Errors were previously disabled because - the setting wasn't writable in Postgres 8.1 and didn't exist in earlier - versions. Now Rails only supports Postgres 8.2+ we're fine to assume the - setting exists. Disabling errors caused problems when using a connection - pooling tool like PgBouncer because it's not guaranteed to have the same - connection between calls to `execute` and it could leave the connection - with errors disabled. - - Fixes #22101. - - *Harry Marr* - -* Set `scope.reordering_value` to `true` if `:reordering`-values are specified. - - Fixes #21886. - - *Hiroaki Izu* - -* Add support for bidirectional destroy dependencies. - - Fixes #13609. - - Example: - - class Content < ActiveRecord::Base - has_one :position, dependent: :destroy - end - - class Position < ActiveRecord::Base - belongs_to :content, dependent: :destroy - end - - *Seb Jacobs* - -* Includes HABTM returns correct size now. It's caused by the join dependency - only instantiates one HABTM object because the join table hasn't a primary key. - - Fixes #16032. - - Examples: - - before: - - Project.first.salaried_developers.size # => 3 - Project.includes(:salaried_developers).first.salaried_developers.size # => 1 - - after: - - Project.first.salaried_developers.size # => 3 - Project.includes(:salaried_developers).first.salaried_developers.size # => 3 - - *Bigxiang* - -* Add option to index errors in nested attributes - - For models which have nested attributes, errors within those models will - now be indexed if :index_errors is specified when defining a - has_many relationship, or if its set in the global config. - - Example: - - class Guitar < ActiveRecord::Base - has_many :tuning_pegs - accepts_nested_attributes_for :tuning_pegs - end - - class TuningPeg < ActiveRecord::Base - belongs_to :guitar - validates_numericality_of :pitch - end - - # Old style - guitar.errors["tuning_pegs.pitch"] = ["is not a number"] - - # New style (if defined globally, or set in has_many_relationship) - guitar.errors["tuning_pegs[1].pitch"] = ["is not a number"] - - *Michael Probber*, *Terence Sun* - -* Exit with non-zero status for failed database rake tasks. - - *Jay Hayes* - -* Queries such as `Computer.joins(:monitor).group(:status).count` will now be - interpreted as `Computer.joins(:monitor).group('computers.status').count` - so that when `Computer` and `Monitor` have both `status` columns we don't - have conflicts in projection. - - *Rafael Sales* - -* Add ability to default to `uuid` as primary key when generating database migrations. - - Example: - - config.generators do |g| - g.orm :active_record, primary_key_type: :uuid - end - - *Jon McCartie* - -* Don't cache arguments in `#find_by` if they are an `ActiveRecord::Relation`. - - Fixes #20817. - - *Hiroaki Izu* - -* Qualify column name inserted by `group` in calculation. - - Giving `group` an unqualified column name now works, even if the relation - has `JOIN` with another table which also has a column of the name. - - *Soutaro Matsumoto* - -* Don't cache prepared statements containing an IN clause or a SQL literal, as - these queries will change often and are unlikely to have a cache hit. - - *Sean Griffin* - -* Fix `rewhere` in a `has_many` association. - - Fixes #21955. - - *Josh Branchaud*, *Kal* - -* `where` raises ArgumentError on unsupported types. - - Fixes #20473. - - *Jake Worth* - -* Add an immutable string type to help reduce memory usage for apps which do - not need mutation detection on strings. - - *Sean Griffin* - -* Give `ActiveRecord::Relation#update` its own deprecation warning when - passed an `ActiveRecord::Base` instance. - - Fixes #21945. - - *Ted Johansson* - -* Make it possible to pass `:to_table` when adding a foreign key through - `add_reference`. - - Fixes #21563. - - *Yves Senn* - -* No longer pass deprecated option `-i` to `pg_dump`. - - *Paul Sadauskas* - -* Concurrent `AR::Base#increment!` and `#decrement!` on the same record - are all reflected in the database rather than overwriting each other. - - *Bogdan Gusiev* - -* Avoid leaking the first relation we call `first` on, per model. - - Fixes #21921. - - *Matthew Draper*, *Jean Boussier* - -* Remove unused `pk_and_sequence_for` in `AbstractMysqlAdapter`. - - *Ryuta Kamizono* - -* Allow fixtures files to set the model class in the YAML file itself. - - To load the fixtures file `accounts.yml` as the `User` model, use: - - _fixture: - model_class: User - david: - name: David - - Fixes #9516. - - *Roque Pinel* - -* Don't require a database connection to load a class which uses acceptance - validations. +* Ensure hashes can be assigned to attributes created using `composed_of`. + Fixes #25210. *Sean Griffin* -* Correctly apply `unscope` when preloading through associations. - - *Jimmy Bourassa* - -* Fixed taking precision into count when assigning a value to timestamp attribute. - - Timestamp column can have less precision than ruby timestamp - In result in how big a fraction of a second can be stored in the - database. - - - m = Model.create! - m.created_at.usec == m.reload.created_at.usec # => false - # due to different precision in Time.now and database column - - If the precision is low enough, (mysql default is 0, so it is always low - enough by default) the value changes when model is reloaded from the - database. This patch fixes that issue ensuring that any timestamp - assigned as an attribute is converted to column precision under the - attribute. - - *Bogdan Gusiev* - -* Introduce `connection.data_sources` and `connection.data_source_exists?`. - These methods determine what relations can be used to back Active Record - models (usually tables and views). - - Also deprecate `SchemaCache#tables`, `SchemaCache#table_exists?` and - `SchemaCache#clear_table_cache!` in favor of their new data source - counterparts. - - *Yves Senn*, *Matthew Draper* - -* Add `ActiveRecord::Base.ignored_columns` to make some columns - invisible from Active Record. - - *Jean Boussier* - -* `ActiveRecord::Tasks::MySQLDatabaseTasks` fails if shellout to - mysql commands (like `mysqldump`) is not successful. - - *Steve Mitchell* - -* Ensure `select` quotes aliased attributes, even when using `from`. - - Fixes #21488. - - *Sean Griffin*, *@johanlunds* - -* MySQL: support `unsigned` numeric data types. - - Example: - - create_table :foos do |t| - t.unsigned_integer :quantity - t.unsigned_bigint :total - t.unsigned_float :percentage - t.unsigned_decimal :price, precision: 10, scale: 2 - end - - The `unsigned: true` option may be used for the primary key: - - create_table :foos, id: :bigint, unsigned: true do |t| - … - end +* Fix logging edge case where if an attribute was of the binary type and + was provided as a Hash. - *Ryuta Kamizono* + *Jon Moss* -* Add `#views` and `#view_exists?` methods on connection adapters. +* Handle JSON deserialization correctly if the column default from database + adapter returns `''` instead of `nil`. - *Ryuta Kamizono* + *Johannes Opper* -* Correctly dump composite primary key. +* Introduce ActiveRecord::TransactionSerializationError for catching + transaction serialization failures or deadlocks. - Example: - - create_table :barcodes, primary_key: ["region", "code"] do |t| - t.string :region - t.integer :code - end - - *Ryuta Kamizono* - -* Lookup the attribute name for `restrict_with_error` messages on the - model class that defines the association. - - *kuboon*, *Ronak Jangir* - -* Correct query for PostgreSQL 8.2 compatibility. - - *Ben Murphy*, *Matthew Draper* - -* `bin/rake db:migrate` uses - `ActiveRecord::Tasks::DatabaseTasks.migrations_paths` instead of - `Migrator.migrations_paths`. - - *Tobias Bielohlawek* - -* Support dropping indexes concurrently in PostgreSQL. - - See http://www.postgresql.org/docs/9.4/static/sql-dropindex.html for more - details. - - *Grey Baker* + *Erol Fornoles* -* Deprecate passing conditions to `ActiveRecord::Relation#delete_all` - and `ActiveRecord::Relation#destroy_all`. +* PostgreSQL: Fix db:structure:load silent failure on SQL error - *Wojciech Wnętrzak* - -* Instantiating an AR model with `ActionController::Parameters` now raises - an `ActiveModel::ForbiddenAttributesError` if the parameters include a - `type` field that has not been explicitly permitted. Previously, the - `type` field was simply ignored in the same situation. - - *Prem Sichanugrist* - -* PostgreSQL, `create_schema`, `drop_schema` and `rename_table` now quote - schema names. - - Fixes #21418. + The command line flag "-v ON_ERROR_STOP=1" should be used + when invoking psql to make sure errors are not suppressed. Example: - create_schema("my.schema") - # CREATE SCHEMA "my.schema"; - - *Yves Senn* - -* PostgreSQL, add `:if_exists` option to `#drop_schema`. This makes it - possible to drop a schema that might exist without raising an exception if - it doesn't. - - *Yves Senn* - -* Only try to nullify has_one target association if the record is persisted. - - Fixes #21223. - - *Agis Anastasopoulos* - -* Uniqueness validator raises descriptive error when running on a persisted - record without primary key. - - Fixes #21304. - - *Yves Senn* - -* Add a native JSON data type support in MySQL. - - Example: - - create_table :json_data_type do |t| - t.json :settings - end - - *Ryuta Kamizono* - -* Descriptive error message when fixtures contain a missing column. - - Fixes #21201. - - *Yves Senn* - -* `ActiveRecord::Tasks::PostgreSQLDatabaseTasks` fail if shellout to - postgresql commands (like `pg_dump`) is not successful. - - *Bryan Paxton*, *Nate Berkopec* - -* Add `ActiveRecord::Relation#in_batches` to work with records and relations - in batches. - - Available options are `of` (batch size), `load`, `start`, and `finish`. - - Examples: - - Person.in_batches.each_record(&:party_all_night!) - Person.in_batches.update_all(awesome: true) - Person.in_batches.delete_all - Person.in_batches.each do |relation| - relation.delete_all - sleep 10 # Throttles the delete queries - end - - Fixes #20933. - - *Sina Siadat* - -* Added methods for PostgreSQL geometric data types to use in migrations. - - Example: - - create_table :foo do |t| - t.line :foo_line - t.lseg :foo_lseg - t.box :foo_box - t.path :foo_path - t.polygon :foo_polygon - t.circle :foo_circle - end - - *Mehmet Emin İNAÇ* - -* Add `cache_key` to ActiveRecord::Relation. - - Example: - - @users = User.where("name like ?", "%Alberto%") - @users.cache_key - # => "/users/query-5942b155a43b139f2471b872ac54251f-3-20150714212107656125000" - - *Alberto Fernández-Capel* - -* Properly allow uniqueness validations on primary keys. - - Fixes #20966. - - *Sean Griffin*, *presskey* - -* Don't raise an error if an association failed to destroy when `destroy` was - called on the parent (as opposed to `destroy!`). - - Fixes #20991. - - *Sean Griffin* - -* `ActiveRecord::RecordNotFound` modified to store model name, primary_key and - id of the caller model. It allows the catcher of this exception to make - a better decision to what to do with it. - - Example: - - class SomeAbstractController < ActionController::Base - rescue_from ActiveRecord::RecordNotFound, with: :redirect_to_404 - - private def redirect_to_404(e) - return redirect_to(posts_url) if e.model == 'Post' - raise - end - end - - *Sameer Rahmani* - -* Deprecate the keys for association `restrict_dependent_destroy` errors in favor - of new key names. - - Previously `has_one` and `has_many` associations were using the - `one` and `many` keys respectively. Both of these keys have special - meaning in I18n (they are considered to be pluralizations) so by - renaming them to `has_one` and `has_many` we make the messages more explicit - and most importantly they don't clash with linguistical systems that need to - validate translation keys (and their pluralizations). - - The `:'restrict_dependent_destroy.one'` key should be replaced with - `:'restrict_dependent_destroy.has_one'`, and `:'restrict_dependent_destroy.many'` - with `:'restrict_dependent_destroy.has_many'`. - - *Roque Pinel*, *Christopher Dell* - -* Fix state being carried over from previous transaction. - - Considering the following example where `name` is a required attribute. - Before we had `new_record?` returning `true` for a persisted record: - - author = Author.create! name: 'foo' - author.name = nil - author.save # => false - author.new_record? # => true - - Fixes #20824. - - *Roque Pinel* - -* Correctly ignore `mark_for_destruction` when `autosave` isn't set to `true` - when validating associations. - - Fixes #20882. - - *Sean Griffin* - -* Fix a bug where counter_cache doesn't always work with polymorphic - relations. - - Fixes #16407. - - *Stefan Kanev*, *Sean Griffin* - -* Ensure that cyclic associations with autosave don't cause duplicate errors - to be added to the parent record. - - Fixes #20874. - - *Sean Griffin* - -* Ensure that `ActionController::Parameters` can still be passed to nested - attributes. - - Fixes #20922. - - *Sean Griffin* - -* Deprecate force association reload by passing a truthy argument to - association method. - - For collection association, you can call `#reload` on association proxy to - force a reload: - - @user.posts.reload # Instead of @user.posts(true) - - For singular association, you can call `#reload` on the parent object to - clear its association cache then call the association method: - - @user.reload.profile # Instead of @user.profile(true) - - Passing a truthy argument to force association to reload will be removed in - Rails 5.1. - - *Prem Sichanugrist* - -* Replaced `ActiveSupport::Concurrency::Latch` with `Concurrent::CountDownLatch` - from the concurrent-ruby gem. - - *Jerry D'Antonio* - -* Fix through associations using scopes having the scope merged multiple - times. - - Fixes #20721. - Fixes #20727. - - *Sean Griffin* - -* `ActiveRecord::Base.dump_schema_after_migration` applies migration tasks - other than `db:migrate`. (eg. `db:rollback`, `db:migrate:dup`, ...) - - Fixes #20743. - - *Yves Senn* - -* Add alternate syntax to make `change_column_default` reversible. - - User can pass in `:from` and `:to` to make `change_column_default` command - become reversible. - - Example: - - change_column_default :posts, :status, from: nil, to: "draft" - change_column_default :users, :authorized, from: true, to: false - - *Prem Sichanugrist* - -* Prevent error when using `force_reload: true` on an unassigned polymorphic - belongs_to association. - - Fixes #20426. - - *James Dabbs* - -* Correctly raise `ActiveRecord::AssociationTypeMismatch` when assigning - a wrong type to a namespaced association. - - Fixes #20545. - - *Diego Carrion* - -* `validates_absence_of` respects `marked_for_destruction?`. - - Fixes #20449. - - *Yves Senn* - -* Include the `Enumerable` module in `ActiveRecord::Relation` - - *Sean Griffin*, *bogdan* - -* Use `Enumerable#sum` in `ActiveRecord::Relation` if a block is given. - - *Sean Griffin* - -* Let `WITH` queries (Common Table Expressions) be explainable. - - *Vladimir Kochnev* - -* Make `remove_index :table, :column` reversible. - - *Yves Senn* - -* Fixed an error which would occur in dirty checking when calling - `update_attributes` from a getter. - - Fixes #20531. - - *Sean Griffin* - -* Make `remove_foreign_key` reversible.

Disabling user triggers does not fulfill what the method promises. - Rails currently requires superuser privileges for this method. - - If you absolutely rely on this behavior, consider patching - `disable_referential_integrity`. - - *Yves Senn* - -* Restore aborted transaction state when `disable_referential_integrity` fails - due to missing permissions. - - *Toby Ovod-Everett*, *Yves Senn* - -* In PostgreSQL, print a warning message if `disable_referential_integrity` - fails due to missing permissions. - - *Andrey Nering*, *Yves Senn* - -* Allow a `:limit` option for MySQL bigint primary key support. - - Example: - - create_table :foos, id: :primary_key, limit: 8 do |t| - end - - # or - - create_table :foos, id: false do |t| - t.primary_key :id, limit: 8 - end - - *Ryuta Kamizono* - -* `belongs_to` will now trigger a validation error by default if the association is not present. - You can turn this off on a per-association basis with `optional: true`. - (Note this new default only applies to new Rails apps that will be generated with - `config.active_record.belongs_to_required_by_default = true` in initializer.) - - *Josef Šimánek* - -* Fixed `ActiveRecord::Relation#becomes!` and `changed_attributes` issues for type - columns. - - Fixes #17139. - - *Miklos Fazekas* - -* Format the time string according to the precision of the time column. - - *Ryuta Kamizono* - -* Allow a `:precision` option for time type columns. - - *Ryuta Kamizono* - -* Add `ActiveRecord::Base.suppress` to prevent the receiver from being saved - during the given block. - - For example, here's a pattern of creating notifications when new comments - are posted. (The notification may in turn trigger an email, a push - notification, or just appear in the UI somewhere): - - class Comment < ActiveRecord::Base - belongs_to :commentable, polymorphic: true - after_create -> { Notification.create! comment: self, - recipients: commentable.recipients } - end - - That's what you want the bulk of the time. A new comment creates a new - Notification. There may be edge cases where you don't want that, like - when copying a commentable and its comments, in which case write a - concern with something like this: - - module Copyable - def copy_to(destination) - Notification.suppress do - # Copy logic that creates new comments that we do not want triggering - # notifications. - end - end - end - - *Michael Ryan* - -* `:time` option added for `#touch`. - - Fixes #18905. - - *Hyonjee Joo* - -* Deprecate passing of `start` value to `find_in_batches` and `find_each` - in favour of `begin_at` value. - - *Vipul A M* - -* Add `foreign_key_exists?` method. - - *Tõnis Simo* - -* Use SQL COUNT and LIMIT 1 queries for `none?` and `one?` methods - if no block or limit is given, instead of loading the entire - collection into memory. This applies to relations (e.g. `User.all`) - as well as associations (e.g. `account.users`) - - # Before: - - users.none? - # SELECT "users".* FROM "users" - - users.one? - # SELECT "users".* FROM "users" - - # After: - - users.none? - # SELECT 1 AS one FROM "users" LIMIT 1 - - users.one? - # SELECT COUNT(*) FROM "users" - - *Eugene Gilburg* - -* Have `enum` perform type casting consistently with the rest of Active - Record, such as `where`. - - *Sean Griffin* - -* `scoping` no longer pollutes the current scope of sibling classes when using - STI. - - Fixes #18806. - - Example: - - StiOne.none.scoping do - StiTwo.all - end - - - *Sean Griffin* - -* `remove_reference` with `foreign_key: true` removes the foreign key before - removing the column. This fixes a bug where it was not possible to remove - the column on MySQL. - - Fixes #18664. - - *Yves Senn* - -* `find_in_batches` now accepts an `:finish` parameter that complements the `:start` - parameter to specify where to stop batch processing. - - *Vipul A M* - -* Fix a rounding problem for PostgreSQL timestamp columns. - - If a timestamp column has a precision specified, it needs to - format according to that. - - *Ryuta Kamizono* - -* Respect the database default charset for `schema_migrations` table. - - The charset of `version` column in `schema_migrations` table depends - on the database default charset and collation rather than the encoding - of the connection. - - *Ryuta Kamizono* - -* Raise `ArgumentError` when passing `nil` or `false` to `Relation#merge`. - - These are not valid values to merge in a relation, so it should warn users - early. - - *Rafael Mendonça França* - -* Use `SCHEMA` instead of `DB_STRUCTURE` for specifying a structure file. - - This makes the `db:structure` tasks consistent with `test:load_structure`. - - *Dieter Komendera* - -* Respect custom primary keys for associations when calling `Relation#where` - - Fixes #18813. - - *Sean Griffin* - -* Fix several edge cases which could result in a counter cache updating - twice or not updating at all for `has_many` and `has_many :through`. - - Fixes #10865. - - *Sean Griffin* - -* Foreign keys added by migrations were given random, generated names. This - meant a different `structure.sql` would be generated every time a developer - ran migrations on their machine. - - The generated part of foreign key names is now a hash of the table name and - column name, which is consistent every time you run the migration. - - *Chris Sinjakli* - -* Validation errors would be raised for parent records when an association - was saved when the parent had `validate: false`. It should not be the - responsibility of the model to validate an associated object unless the - object was created or modified by the parent. - - This fixes the issue by skipping validations if the parent record is - persisted, not changed, and not marked for destruction. - - Fixes #17621. - - *Eileen M. Uchitelle*, *Aaron Patterson* - -* Fix n+1 query problem when eager loading nil associations (fixes #18312) - - *Sammy Larbi* - -* Change the default error message from `can't be blank` to `must exist` for - the presence validator of the `:required` option on `belongs_to`/`has_one` - associations. - - *Henrik Nygren* - -* Fixed `ActiveRecord::Relation#group` method when an argument is an SQL - reserved keyword: - - Example: - - SplitTest.group(:key).count - Property.group(:value).count - - *Bogdan Gusiev* - -* Added the `#or` method on `ActiveRecord::Relation`, allowing use of the OR - operator to combine WHERE or HAVING clauses. - - Example: - - Post.where('id = 1').or(Post.where('id = 2')) - # => SELECT * FROM posts WHERE (id = 1) OR (id = 2) - - *Sean Griffin*, *Matthew Draper*, *Gael Muller*, *Olivier El Mekki* - -* Don't define autosave association callbacks twice from - `accepts_nested_attributes_for`. - - Fixes #18704. - - *Sean Griffin* - -* Integer types will no longer raise a `RangeError` when assigning an - attribute, but will instead raise when going to the database. - - Fixes several vague issues which were never reported directly. See the - commit message from the commit which added this line for some examples. - - *Sean Griffin* - -* Values which would error while being sent to the database (such as an - ASCII-8BIT string with invalid UTF-8 bytes on SQLite3), no longer error on - assignment. They will still error when sent to the database, but you are - given the ability to re-assign it to a valid value. - - Fixes #18580. - - *Sean Griffin* - -* Don't remove join dependencies in `Relation#exists?` - - Fixes #18632. - - *Sean Griffin* - -* Invalid values assigned to a JSON column are assumed to be `nil`. - - Fixes #18629. - - *Sean Griffin* - -* Add `ActiveRecord::Base#accessed_fields`, which can be used to quickly - discover which fields were read from a model when you are looking to only - select the data you need from the database. - - *Sean Griffin* - -* Introduce the `:if_exists` option for `drop_table`. - - Example: - - drop_table(:posts, if_exists: true) - - That would execute: - - DROP TABLE IF EXISTS posts - - If the table doesn't exist, `if_exists: false` (the default) raises an - exception whereas `if_exists: true` does nothing. - - *Cody Cutrer*, *Stefan Kanev*, *Ryuta Kamizono* - -* Don't run SQL if attribute value is not changed for update_attribute method. - - *Prathamesh Sonpatki* - -* `time` columns can now get affected by `time_zone_aware_attributes`. If you have - set `config.time_zone` to a value other than `'UTC'`, they will be treated - as in that time zone by default in Rails 5.1. If this is not the desired - behavior, you can set - - ActiveRecord::Base.time_zone_aware_types = [:datetime] - - A deprecation warning will be emitted if you have a `:time` column, and have - not explicitly opted out. - - Fixes #3145. - - *Sean Griffin* - -* Tests now run after_commit callbacks. You no longer have to declare - `uses_transaction ‘test name’` to test the results of an after_commit. - - after_commit callbacks run after committing a transaction whose parent - is not `joinable?`: un-nested transactions, transactions within test cases, - and transactions in `console --sandbox`. - - *arthurnn*, *Ravil Bayramgalin*, *Matthew Draper* - -* `nil` as a value for a binary column in a query no longer logs as - "<NULL binary data>", and instead logs as just "nil". - - *Sean Griffin* - -* `attribute_will_change!` will no longer cause non-persistable attributes to - be sent to the database. - - Fixes #18407. - - *Sean Griffin* - -* Remove support for the `protected_attributes` gem. - - *Carlos Antonio da Silva*, *Roberto Miranda* - -* Fix accessing of fixtures having non-string labels like Fixnum. - - *Prathamesh Sonpatki* - -* Remove deprecated support to preload instance-dependent associations. - - *Yves Senn* - -* Remove deprecated support for PostgreSQL ranges with exclusive lower bounds. - - *Yves Senn* - -* Remove deprecation when modifying a relation with cached Arel. - This raises an `ImmutableRelation` error instead. - - *Yves Senn* - -* Added `ActiveRecord::SecureToken` in order to encapsulate generation of - unique tokens for attributes in a model using `SecureRandom`. - - *Roberto Miranda* - -* Change the behavior of boolean columns to be closer to Ruby's semantics. - - Before this change we had a small set of "truthy", and all others are "falsy". - - Now, we have a small set of "falsy" values and all others are "truthy" matching - Ruby's semantics. - - *Rafael Mendonça França* - -* Deprecate `ActiveRecord::Base.errors_in_transactional_callbacks=`. - - *Rafael Mendonça França* - -* Change transaction callbacks to not swallow errors. - - Before this change any errors raised inside a transaction callback - were getting rescued and printed in the logs. - - Now these errors are not rescued anymore and just bubble up, as the other callbacks. - - *Rafael Mendonça França* - -* Remove deprecated `sanitize_sql_hash_for_conditions`. - - *Rafael Mendonça França* - -* Remove deprecated `Reflection#source_macro`. - - *Rafael Mendonça França* - -* Remove deprecated `symbolized_base_class` and `symbolized_sti_name`. - - *Rafael Mendonça França* - -* Remove deprecated `ActiveRecord::Base.disable_implicit_join_references=`. - - *Rafael Mendonça França* - -* Remove deprecated access to connection specification using a string accessor. - - Now all strings will be handled as a URL. - - *Rafael Mendonça França* - -* Change the default `null` value for `timestamps` to `false`. - - *Rafael Mendonça França* - -* Return an array of pools from `connection_pools`. - - *Rafael Mendonça França* - -* Return a null column from `column_for_attribute` when no column exists. - - *Rafael Mendonça França* - -* Remove deprecated `serialized_attributes`. - - *Rafael Mendonça França* - -* Remove deprecated automatic counter caches on `has_many :through`. - - *Rafael Mendonça França* - -* Change the way in which callback chains can be halted. - - The preferred method to halt a callback chain from now on is to explicitly - `throw(:abort)`. - In the past, returning `false` in an Active Record `before_` callback had the - side effect of halting the callback chain. - This is not recommended anymore and, depending on the value of the - `ActiveSupport.halt_callback_chains_on_return_false` option, will - either not work at all or display a deprecation warning. - - *claudiob* - -* Clear query cache on rollback. - - *Florian Weingarten* - -* Fix setting of foreign_key for through associations when building a new record. - - Fixes #12698. - - *Ivan Antropov* - -* Improve dumping of the primary key. If it is not a default primary key, - correctly dump the type and options. - - Fixes #14169, #16599. - - *Ryuta Kamizono* - -* Format the datetime string according to the precision of the datetime field. - - Incompatible to rounding behavior between MySQL 5.6 and earlier. - - In 5.5, when you insert `2014-08-17 12:30:00.999999` the fractional part - is ignored. In 5.6, it's rounded to `2014-08-17 12:30:01`: - - http://bugs.mysql.com/bug.php?id=68760 - - *Ryuta Kamizono* - -* Allow a precision option for MySQL datetimes. - - *Ryuta Kamizono* - -* Fixed automatic `inverse_of` for models nested in a module. - - *Andrew McCloud* - -* Change `ActiveRecord::Relation#update` behavior so that it can - be called without passing ids of the records to be updated. - - This change allows updating multiple records returned by - `ActiveRecord::Relation` with callbacks and validations. - - # Before - # ArgumentError: wrong number of arguments (1 for 2) - Comment.where(group: 'expert').update(body: "Group of Rails Experts") - - # After - # Comments with group expert updated with body "Group of Rails Experts" - Comment.where(group: 'expert').update(body: "Group of Rails Experts") - - *Prathamesh Sonpatki* - -* Fix `reaping_frequency` option when the value is a string. - - This usually happens when it is configured using `DATABASE_URL`. - - *korbin* - -* Fix error message when trying to create an associated record and the foreign - key is missing. - - Before this fix the following exception was being raised: - - NoMethodError: undefined method `val' for #<Arel::Nodes::BindParam:0x007fc64d19c218> - - Now the message is: - - ActiveRecord::UnknownAttributeError: unknown attribute 'foreign_key' for Model. - - *Rafael Mendonça França* - -* Fix change detection problem for PostgreSQL bytea type and - `ArgumentError: string contains null byte` exception with pg-0.18. - - Fixes #17680. - - *Lars Kanis* - -* When a table has a composite primary key, the `primary_key` method for - SQLite3 and PostgreSQL adapters was only returning the first field of the key. - Ensures that it will return nil instead, as Active Record doesn't support - composite primary keys. - - Fixes #18070. - - *arthurnn* - -* `validates_size_of` / `validates_length_of` do not count records - which are `marked_for_destruction?`. - - Fixes #7247. - - *Yves Senn* - -* Ensure `first!` and friends work on loaded associations. - - Fixes #18237. - - *Sean Griffin* - -* `eager_load` preserves readonly flag for associations. - - Fixes #15853. - - *Takashi Kokubun* - -* Provide `:touch` option to `save()` to accommodate saving without updating - timestamps. - - Fixes #18202. - - *Dan Olson* - -* Provide a more helpful error message when an unsupported class is passed to - `serialize`. - - Fixes #18224. - - *Sean Griffin* - -* Add bigint primary key support for MySQL. - - Example: - - create_table :foos, id: :bigint do |t| - end - - *Ryuta Kamizono* - -* Support for any type of primary key. - - Fixes #14194. - - *Ryuta Kamizono* - -* Dump the default `nil` for PostgreSQL UUID primary key. - - *Ryuta Kamizono* - -* Add a `:foreign_key` option to `references` and associated migration - methods.
