Never perform additional SQL on loaded relation - 2. Use SQL reverse order instead of loading relation if relation doesn't have limit - 3. Deprecated relation loading when SQL order can not be automatically reversed +* Deprecate passing arguments and block at the same time to + `ActiveRecord::QueryMethods#select`. - Topic.order("title").load.last(3) - # before: SELECT ... - # after: No SQL - - Topic.order("title").last - # before: SELECT * FROM `topics` - # after: SELECT * FROM `topics` ORDER BY `topics`.`title` DESC LIMIT 1 - - Topic.order("coalesce(author, title)").last - # before: SELECT * FROM `topics` - # after: Deprecation Warning for irreversible order - - *Bogdan Gusiev* - -* Allow `joins` to be unscoped. - - Closes #13775. - - *Takashi Kokubun* - -* Add ActiveRecord `#second_to_last` and `#third_to_last` methods. - - *Brian Christian* - -* Added `numeric` helper into migrations. - - Example: - - create_table(:numeric_types) do |t| - t.numeric :numeric_type, precision: 10, scale: 2 - end - - *Mehmet Emin İNAÇ* - -* Bumped the minimum supported version of PostgreSQL to >= 9.1. - Both PG 9.0 and 8.4 are past their end of life date: - http://www.postgresql.org/support/versioning/ - - *Remo Mueller* - -## Rails 5.0.0.beta2 (February 01, 2016) ## - -* `ActiveRecord::Relation#reverse_order` throws `ActiveRecord::IrreversibleOrderError` - when the order can not be reversed using current trivial algorithm. - Also raises the same error when `#reverse_order` is called on - relation without any order and table has no primary key: - - Topic.order("concat(author_name, title)").reverse_order - # Before: SELECT `topics`.* FROM `topics` ORDER BY concat(author_name DESC, title) DESC - # After: raises ActiveRecord::IrreversibleOrderError - Edge.all.reverse_order - # Before: SELECT `edges`.* FROM `edges` ORDER BY `edges`.`` DESC - # After: raises ActiveRecord::IrreversibleOrderError - - *Bogdan Gusiev* - -* Improve schema_migrations insertion performance by inserting all versions - in one INSERT SQL. - - *Akira Matsuda*, *Naoto Koshikawa* - -* Using `references` or `belongs_to` in migrations will always add index - for the referenced column by default, without adding `index: true` option - to generated migration file. 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 + *Prathamesh Sonpatki* - *Bigxiang* +* Optimistic locking: Added ability update locking_column value. + Ignore optimistic locking if update with new locking_column value. -* Add option to index errors in nested attributes + *bogdanvlviv* - 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. +* Fixed: Optimistic locking does not work well with null in the database. - Example: + Fixes #26024 - class Guitar < ActiveRecord::Base - has_many :tuning_pegs - accepts_nested_attributes_for :tuning_pegs - end + *bogdanvlviv* - class TuningPeg < ActiveRecord::Base - belongs_to :guitar - validates_numericality_of :pitch - end +* Fixed support for case insensitive comparisons of `text` columns in + PostgreSQL. - # Old style - guitar.errors["tuning_pegs.pitch"] = ["is not a number"] + *Edho Arief* - # New style (if defined globally, or set in has_many_relationship) - guitar.errors["tuning_pegs[1].pitch"] = ["is not a number"] +* Serialize JSON attribute value `nil` as SQL `NULL`, not JSON `null` - *Michael Probber*, *Terence Sun* + *Trung Duc Tran* -* Exit with non-zero status for failed database rake tasks. +* Return `true` from `update_attribute` when the value of the attribute + to be updated is unchanged. - *Jay Hayes* + Fixes #26593. -* 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. + *Prathamesh Sonpatki* - *Rafael Sales* +* Always store errors details information with symbols. -* Add ability to default to `uuid` as primary key when generating database migrations. + When the association is autosaved we were storing the details with + string keys. This was creating inconsistency with other details that are + added using the `Errors#add` method. It was also inconsistent with the + `Errors#messages` storage. - Example: + To fix this inconsistency we are always storing with symbols. This will + cause a small breaking change because in those cases the details could + be accessed as strings keys but now it can not. - config.generators do |g| - g.orm :active_record, primary_key_type: :uuid - end + Fix #26499. - *Jon McCartie* + *Rafael Mendonça França*, *Marcus Vieira* -* Don't cache arguments in `#find_by` if they are an `ActiveRecord::Relation`. +* Calling `touch` on a model using optimistic locking will now leave the model + in a non-dirty state with no attribute changes. - Fixes #20817. + Fixes #26496. - *Hiroaki Izu* + *Jakob Skjerning* -* Qualify column name inserted by `group` in calculation. +* Using a mysql2 connection after it fails to reconnect will now have an error message + saying the connection is closed rather than an undefined method error message. - 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. + *Dylan Thacker-Smith* - *Soutaro Matsumoto* +* PostgreSQL array columns will now respect the encoding of strings contained + in the array. -* 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. + Fixes #26326. *Sean Griffin* -* Fix `rewhere` in a `has_many` association. - - Fixes #21955. - - *Josh Branchaud*, *Kal* - -* `where` raises ArgumentError on unsupported types. - - Fixes #20473. +* Inverse association instances will now be set before `after_find` or + `after_initialize` callbacks are run. - *Jake Worth* - -* Add an immutable string type to help reduce memory usage for apps which do - not need mutation detection on strings. + Fixes #26320. *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* +* Remove unnecessarily association load when a `belongs_to` association has already been + loaded then the foreign key is changed directly and the record saved. -* No longer pass deprecated option `-i` to `pg_dump`. + *James Coleman* - *Paul Sadauskas* +* Remove standardized column types/arguments spaces in schema dump. -* Concurrent `AR::Base#increment!` and `#decrement!` on the same record - are all reflected in the database rather than overwriting each other. + *Tim Petricola* - *Bogdan Gusiev* +* Avoid loading records from database when they are already loaded using + the `pluck` method on a collection. -* 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`. + Fixes #25921. *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. - - *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 - - *Ryuta Kamizono* - -* Add `#views` and `#view_exists?` methods on connection adapters. - - *Ryuta Kamizono* - -* Correctly dump composite primary key. - - 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/rails 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* - -* Deprecate passing conditions to `ActiveRecord::Relation#delete_all` - and `ActiveRecord::Relation#destroy_all`. - - *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. - - 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 +* Remove text default treated as an empty string in non-strict mode for + consistency with other types. + + Strict mode controls how MySQL handles invalid or missing values in + data-change statements such as INSERT or UPDATE.

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.

The #belongs_to association is always used in the model that has - # the foreign key. - # - # === One-to-one - # - # Use #has_one in the base, and #belongs_to in the associated model. - # - # class Employee < ActiveRecord::Base - # has_one :office - # end - # class Office < ActiveRecord::Base - # belongs_to :employee # foreign key - employee_id - # end - # - # === One-to-many - # - # Use #has_many in the base, and #belongs_to in the associated model. - # - # class Manager < ActiveRecord::Base - # has_many :employees - # end - # class Employee < ActiveRecord::Base - # belongs_to :manager # foreign key - manager_id - # end - # - # === Many-to-many - # - # There are two ways to build a many-to-many relationship. - # - # The first way uses a #has_many association with the <tt>:through</tt> option and a join model, so - # there are two stages of associations. - # - # class Assignment < ActiveRecord::Base - # belongs_to :programmer # foreign key - programmer_id - # belongs_to :project # foreign key - project_id - # end - # class Programmer < ActiveRecord::Base - # has_many :assignments - # has_many :projects, through: :assignments - # end - # class Project < ActiveRecord::Base - # has_many :assignments - # has_many :programmers, through: :assignments - # end - # - # For the second way, use #has_and_belongs_to_many in both models. This requires a join table - # that has no corresponding model or primary key. - # - # class Programmer < ActiveRecord::Base - # has_and_belongs_to_many :projects # foreign keys in the join table - # end - # class Project < ActiveRecord::Base - # has_and_belongs_to_many :programmers # foreign keys in the join table - # end - # - # Choosing which way to build a many-to-many relationship is not always simple. - # If you need to work with the relationship model as its own entity, - # use #has_many <tt>:through</tt>. Use #has_and_belongs_to_many when working with legacy schemas or when - # you never work directly with the relationship itself. - # - # == Is it a #belongs_to or #has_one association? - # - # Both express a 1-1 relationship. The difference is mostly where to place the foreign - # key, which goes on the table for the class declaring the #belongs_to relationship. - # - # class User < ActiveRecord::Base - # # I reference an account. - # belongs_to :account - # end - # - # class Account < ActiveRecord::Base - # # One user references me. - # has_one :user - # end - # - # The tables for these classes could look something like: - # - # CREATE TABLE users ( - # id int NOT NULL auto_increment, - # account_id int default NULL, - # name varchar default NULL, - # PRIMARY KEY (id) - # ) - # - # CREATE TABLE accounts ( - # id int NOT NULL auto_increment, - # name varchar default NULL, - # PRIMARY KEY (id) - # ) - # - # == Unsaved objects and associations - # - # You can manipulate objects and associations before they are saved to the database, but - # there is some special behavior you should be aware of, mostly involving the saving of - # associated objects. - # - # You can set the <tt>:autosave</tt> option on a #has_one, #belongs_to, - # #has_many, or #has_and_belongs_to_many association. Setting it - # to +true+ will _always_ save the members, whereas setting it to +false+ will - # _never_ save the members. More details about <tt>:autosave</tt> option is available at - # AutosaveAssociation. - # - # === One-to-one associations - # - # * Assigning an object to a #has_one association automatically saves that object and - # the object being replaced (if there is one), in order to update their foreign - # keys - except if the parent object is unsaved (<tt>new_record? == true</tt>). - # * If either of these saves fail (due to one of the objects being invalid), an - # ActiveRecord::RecordNotSaved exception is raised and the assignment is - # cancelled. - # * If you wish to assign an object to a #has_one association without saving it, - # use the <tt>#build_association</tt> method (documented below). The object being - # replaced will still be saved to update its foreign key. - # * Assigning an object to a #belongs_to association does not save the object, since - # the foreign key field belongs on the parent. It does not save the parent either. - # - # === Collections - # - # * Adding an object to a collection (#has_many or #has_and_belongs_to_many) automatically - # saves that object, except if the parent object (the owner of the collection) is not yet - # stored in the database. - # * If saving any of the objects being added to a collection (via <tt>push</tt> or similar) - # fails, then <tt>push</tt> returns +false+. - # * If saving fails while replacing the collection (via <tt>association=</tt>), an - # ActiveRecord::RecordNotSaved exception is raised and the assignment is - # cancelled. - # * You can add an object to a collection without automatically saving it by using the - # <tt>collection.build</tt> method (documented below). - # * All unsaved (<tt>new_record? == true</tt>) members of the collection are automatically - # saved when the parent is saved. - # - # == Customizing the query - # - # \Associations are built from <tt>Relation</tt>s, and you can use the Relation syntax - # to customize them. For example, to add a condition: - # - # class Blog < ActiveRecord::Base - # has_many :published_posts, -> { where(published: true) }, class_name: 'Post' - # end - # - # Inside the <tt>-> { ... }</tt> block you can use all of the usual Relation methods. - # - # === Accessing the owner object - # - # Sometimes it is useful to have access to the owner object when building the query. The owner - # is passed as a parameter to the block. For example, the following association would find all - # events that occur on the user's birthday: - # - # class User < ActiveRecord::Base - # has_many :birthday_events, ->(user) { where(starts_on: user.birthday) }, class_name: 'Event' - # end - # - # Note: Joining, eager loading and preloading of these associations is not fully possible. - # These operations happen before instance creation and the scope will be called with a +nil+ argument. - # This can lead to unexpected behavior and is deprecated. - # - # == Association callbacks - # - # Similar to the normal callbacks that hook into the life cycle of an Active Record object, - # you can also define callbacks that get triggered when you add an object to or remove an - # object from an association collection. - # - # class Project - # has_and_belongs_to_many :developers, after_add: :evaluate_velocity - # - # def evaluate_velocity(developer) - # ... - # end - # end - # - # It's possible to stack callbacks by passing them as an array. Example: - # - # class Project - # has_and_belongs_to_many :developers, - # after_add: [:evaluate_velocity, Proc.new { |p, d| p.shipping_date = Time.now}] - # end - # - # Possible callbacks are: +before_add+, +after_add+, +before_remove+ and +after_remove+. - # - # If any of the +before_add+ callbacks throw an exception, the object will not be - # added to the collection. - # - # Similarly, if any of the +before_remove+ callbacks throw an exception, the object - # will not be removed from the collection. - # - # == Association extensions - # - # The proxy objects that control the access to associations can be extended through anonymous - # modules. This is especially beneficial for adding new finders, creators, and other - # factory-type methods that are only used as part of this association. - # - # class Account < ActiveRecord::Base - # has_many :people do - # def find_or_create_by_name(name) - # first_name, last_name = name.split(" ", 2) - # find_or_create_by(first_name: first_name, last_name: last_name) - # end - # end - # end - # - # person = Account.first.people.find_or_create_by_name("David Heinemeier Hansson") - # person.first_name # => "David" - # person.last_name # => "Heinemeier Hansson" - # - # If you need to share the same extensions between many associations, you can use a named - # extension module. - # - # module FindOrCreateByNameExtension - # def find_or_create_by_name(name) - # first_name, last_name = name.split(" ", 2) - # find_or_create_by(first_name: first_name, last_name: last_name) - # end - # end - # - # class Account < ActiveRecord::Base - # has_many :people, -> { extending FindOrCreateByNameExtension } - # end - # - # class Company < ActiveRecord::Base - # has_many :people, -> { extending FindOrCreateByNameExtension } - # end - # - # Some extensions can only be made to work with knowledge of the association's internals. - # Extensions can access relevant state using the following methods (where +items+ is the - # name of the association): - # - # * <tt>record.association(:items).owner</tt> - Returns the object the association is part of. - # * <tt>record.association(:items).reflection</tt> - Returns the reflection object that describes the association. - # * <tt>record.association(:items).target</tt> - Returns the associated object for #belongs_to and #has_one, or - # the collection of associated objects for #has_many and #has_and_belongs_to_many. - # - # However, inside the actual extension code, you will not have access to the <tt>record</tt> as - # above. In this case, you can access <tt>proxy_association</tt>. For example, - # <tt>record.association(:items)</tt> and <tt>record.items.proxy_association</tt> will return - # the same object, allowing you to make calls like <tt>proxy_association.owner</tt> inside - # association extensions. - # - # == Association Join Models - # - # Has Many associations can be configured with the <tt>:through</tt> option to use an - # explicit join model to retrieve the data. This operates similarly to a - # #has_and_belongs_to_many association. The advantage is that you're able to add validations, - # callbacks, and extra attributes on the join model. Consider the following schema: - # - # class Author < ActiveRecord::Base - # has_many :authorships - # has_many :books, through: :authorships - # end - # - # class Authorship < ActiveRecord::Base - # belongs_to :author - # belongs_to :book - # end - # - # @author = Author.first - # @author.authorships.collect { |a| a.book } # selects all books that the author's authorships belong to - # @author.books # selects all books by using the Authorship join model - # - # You can also go through a #has_many association on the join model: - # - # class Firm < ActiveRecord::Base - # has_many :clients - # has_many :invoices, through: :clients - # end - # - # class Client < ActiveRecord::Base - # belongs_to :firm - # has_many :invoices - # end - # - # class Invoice < ActiveRecord::Base - # belongs_to :client - # end - # - # @firm = Firm.first - # @firm.clients.flat_map { |c| c.invoices } # select all invoices for all clients of the firm - # @firm.invoices # selects all invoices by going through the Client join model - # - # Similarly you can go through a #has_one association on the join model: - # - # class Group < ActiveRecord::Base - # has_many :users - # has_many :avatars, through: :users - # end - # - # class User < ActiveRecord::Base - # belongs_to :group - # has_one :avatar - # end - # - # class Avatar < ActiveRecord::Base - # belongs_to :user - # end - # - # @group = Group.first - # @group.users.collect { |u| u.avatar }.compact # select all avatars for all users in the group - # @group.avatars # selects all avatars by going through the User join model. - # - # An important caveat with going through #has_one or #has_many associations on the - # join model is that these associations are *read-only*. For example, the following - # would not work following the previous example: - # - # @group.avatars << Avatar.new # this would work if User belonged_to Avatar rather than the other way around - # @group.avatars.delete(@group.avatars.last) # so would this - # - # == Setting Inverses - # - # If you are using a #belongs_to on the join model, it is a good idea to set the - # <tt>:inverse_of</tt> option on the #belongs_to, which will mean that the following example - # works correctly (where <tt>tags</tt> is a #has_many <tt>:through</tt> association): - # - # @post = Post.first - # @tag = @post.tags.build name: "ruby" - # @tag.save - # - # The last line ought to save the through record (a <tt>Tagging</tt>). This will only work if the - # <tt>:inverse_of</tt> is set: - # - # class Tagging < ActiveRecord::Base - # belongs_to :post - # belongs_to :tag, inverse_of: :taggings - # end - # - # If you do not set the <tt>:inverse_of</tt> record, the association will - # do its best to match itself up with the correct inverse. Automatic - # inverse detection only works on #has_many, #has_one, and - # #belongs_to associations. - # - # Extra options on the associations, as defined in the - # <tt>AssociationReflection::INVALID_AUTOMATIC_INVERSE_OPTIONS</tt> constant, will - # also prevent the association's inverse from being found automatically. - # - # The automatic guessing of the inverse association uses a heuristic based - # on the name of the class, so it may not work for all associations, - # especially the ones with non-standard names. - # - # You can turn off the automatic detection of inverse associations by setting - # the <tt>:inverse_of</tt> option to <tt>false</tt> like so: - # - # class Tagging < ActiveRecord::Base - # belongs_to :tag, inverse_of: false - # end - # - # == Nested \Associations - # - # You can actually specify *any* association with the <tt>:through</tt> option, including an - # association which has a <tt>:through</tt> option itself. For example: - # - # class Author < ActiveRecord::Base - # has_many :posts - # has_many :comments, through: :posts - # has_many :commenters, through: :comments - # end - # - # class Post < ActiveRecord::Base - # has_many :comments - # end - # - # class Comment < ActiveRecord::Base - # belongs_to :commenter - # end - # - # @author = Author.first - # @author.commenters # => People who commented on posts written by the author - # - # An equivalent way of setting up this association this would be: - # - # class Author < ActiveRecord::Base - # has_many :posts - # has_many :commenters, through: :posts - # end - # - # class Post < ActiveRecord::Base - # has_many :comments - # has_many :commenters, through: :comments - # end - # - # class Comment < ActiveRecord::Base - # belongs_to :commenter - # end - # - # When using a nested association, you will not be able to modify the association because there - # is not enough information to know what modification to make. For example, if you tried to - # add a <tt>Commenter</tt> in the example above, there would be no way to tell how to set up the - # intermediate <tt>Post</tt> and <tt>Comment</tt> objects. - # - # == Polymorphic \Associations - # - # Polymorphic associations on models are not restricted on what types of models they - # can be associated with. Rather, they specify an interface that a #has_many association - # must adhere to. - # - # class Asset < ActiveRecord::Base - # belongs_to :attachable, polymorphic: true - # end - # - # class Post < ActiveRecord::Base - # has_many :assets, as: :attachable # The :as option specifies the polymorphic interface to use. - # end - # - # @asset.attachable = @post - # - # This works by using a type column in addition to a foreign key to specify the associated - # record. In the Asset example, you'd need an +attachable_id+ integer column and an - # +attachable_type+ string column. - # - # Using polymorphic associations in combination with single table inheritance (STI) is - # a little tricky. In order for the associations to work as expected, ensure that you - # store the base model for the STI models in the type column of the polymorphic - # association. To continue with the asset example above, suppose there are guest posts - # and member posts that use the posts table for STI. In this case, there must be a +type+ - # column in the posts table. - # - # Note: The <tt>attachable_type=</tt> method is being called when assigning an +attachable+. - # The +class_name+ of the +attachable+ is passed as a String. - # - # class Asset < ActiveRecord::Base - # belongs_to :attachable, polymorphic: true - # - # def attachable_type=(class_name) - # super(class_name.constantize.base_class.to_s) - # end - # end - # - # class Post < ActiveRecord::Base - # # because we store "Post" in attachable_type now dependent: :destroy will work - # has_many :assets, as: :attachable, dependent: :destroy - # end - # - # class GuestPost < Post - # end - # - # class MemberPost < Post - # end - # - # == Caching - # - # All of the methods are built on a simple caching principle that will keep the result - # of the last query around unless specifically instructed not to. The cache is even - # shared across methods to make it even cheaper to use the macro-added methods without - # worrying too much about performance at the first go. - # - # project.milestones # fetches milestones from the database - # project.milestones.size # uses the milestone cache - # project.milestones.empty? # uses the milestone cache - # project.milestones(true).size # fetches milestones from the database - # project.milestones # uses the milestone cache - # - # == Eager loading of associations - # - # Eager loading is a way to find objects of a certain class and a number of named associations. - # It is one of the easiest ways to prevent the dreaded N+1 problem in which fetching 100 - # posts that each need to display their author triggers 101 database queries. Through the - # use of eager loading, the number of queries will be reduced from 101 to 2. - # - # class Post < ActiveRecord::Base - # belongs_to :author - # has_many :comments - # end - # - # Consider the following loop using the class above: - # - # Post.all.each do |post| - # puts "Post: " + post.title - # puts "Written by: " + post.author.name - # puts "Last comment on: " + post.comments.first.created_on - # end - # - # To iterate over these one hundred posts, we'll generate 201 database queries. Let's - # first just optimize it for retrieving the author: - # - # Post.includes(:author).each do |post| - # - # This references the name of the #belongs_to association that also used the <tt>:author</tt> - # symbol. After loading the posts, find will collect the +author_id+ from each one and load - # all the referenced authors with one query. Doing so will cut down the number of queries - # from 201 to 102. - # - # We can improve upon the situation further by referencing both associations in the finder with: - # - # Post.includes(:author, :comments).each do |post| - # - # This will load all comments with a single query. This reduces the total number of queries - # to 3. In general, the number of queries will be 1 plus the number of associations - # named (except if some of the associations are polymorphic #belongs_to - see below). - # - # To include a deep hierarchy of associations, use a hash: - # - # Post.includes(:author, { comments: { author: :gravatar } }).each do |post| - # - # The above code will load all the comments and all of their associated - # authors and gravatars. You can mix and match any combination of symbols, - # arrays, and hashes to retrieve the associations you want to load. - # - # All of this power shouldn't fool you into thinking that you can pull out huge amounts - # of data with no performance penalty just because you've reduced the number of queries. - # The database still needs to send all the data to Active Record and it still needs to - # be processed. So it's no catch-all for performance problems, but it's a great way to - # cut down on the number of queries in a situation as the one described above. - # - # Since only one table is loaded at a time, conditions or orders cannot reference tables - # other than the main one. If this is the case, Active Record falls back to the previously - # used LEFT OUTER JOIN based strategy. For example: - # - # Post.includes([:author, :comments]).where(['comments.approved = ?', true]) - # - # This will result in a single SQL query with joins along the lines of: - # <tt>LEFT OUTER JOIN comments ON comments.post_id = posts.id</tt> and - # <tt>LEFT OUTER JOIN authors ON authors.id = posts.author_id</tt>. Note that using conditions - # like this can have unintended consequences. - # In the above example posts with no approved comments are not returned at all, because - # the conditions apply to the SQL statement as a whole and not just to the association. - # - # You must disambiguate column references for this fallback to happen, for example - # <tt>order: "author.name DESC"</tt> will work but <tt>order: "name DESC"</tt> will not. - # - # If you want to load all posts (including posts with no approved comments) then write - # your own LEFT OUTER JOIN query using ON - # - # Post.joins("LEFT OUTER JOIN comments ON comments.post_id = posts.id AND comments.approved = '1'") - # - # In this case it is usually more natural to include an association which has conditions defined on it: - # - # class Post < ActiveRecord::Base - # has_many :approved_comments, -> { where(approved: true) }, class_name: 'Comment' - # end - # - # Post.includes(:approved_comments) - # - # This will load posts and eager load the +approved_comments+ association, which contains - # only those comments that have been approved. - # - # If you eager load an association with a specified <tt>:limit</tt> option, it will be ignored, - # returning all the associated objects: - # - # class Picture < ActiveRecord::Base - # has_many :most_recent_comments, -> { order('id DESC').limit(10) }, class_name: 'Comment' - # end - # - # Picture.includes(:most_recent_comments).first.most_recent_comments # => returns all associated comments. - # - # Eager loading is supported with polymorphic associations. - # - # class Address < ActiveRecord::Base - # belongs_to :addressable, polymorphic: true - # end - # - # A call that tries to eager load the addressable model - # - # Address.includes(:addressable) - # - # This will execute one query to load the addresses and load the addressables with one - # query per addressable type. - # For example if all the addressables are either of class Person or Company then a total - # of 3 queries will be executed. The list of addressable types to load is determined on - # the back of the addresses loaded. This is not supported if Active Record has to fallback - # to the previous implementation of eager loading and will raise ActiveRecord::EagerLoadPolymorphicError. - # The reason is that the parent model's type is a column value so its corresponding table - # name cannot be put in the +FROM+/+JOIN+ clauses of that query. - # - # == Table Aliasing - # - # Active Record uses table aliasing in the case that a table is referenced multiple times - # in a join. If a table is referenced only once, the standard table name is used. The - # second time, the table is aliased as <tt>#{reflection_name}_#{parent_table_name}</tt>. - # Indexes are appended for any more successive uses of the table name. - # - # Post.joins(:comments) - # # => SELECT ... FROM posts INNER JOIN comments ON ... - # Post.joins(:special_comments) # STI - # # => SELECT ... FROM posts INNER JOIN comments ON ... AND comments.type = 'SpecialComment' - # Post.joins(:comments, :special_comments) # special_comments is the reflection name, posts is the parent table name - # # => SELECT ... FROM posts INNER JOIN comments ON ... INNER JOIN comments special_comments_posts - # - # Acts as tree example: - # - # TreeMixin.joins(:children) - # # => SELECT ... FROM mixins INNER JOIN mixins childrens_mixins ... - # TreeMixin.joins(children: :parent) - # # => SELECT ... FROM mixins INNER JOIN mixins childrens_mixins ... - # INNER JOIN parents_mixins ... - # TreeMixin.joins(children: {parent: :children}) - # # => SELECT ... FROM mixins INNER JOIN mixins childrens_mixins ... - # INNER JOIN parents_mixins ... - # INNER JOIN mixins childrens_mixins_2 - # - # Has and Belongs to Many join tables use the same idea, but add a <tt>_join</tt> suffix: - # - # Post.joins(:categories) - # # => SELECT ... FROM posts INNER JOIN categories_posts ... INNER JOIN categories ... - # Post.joins(categories: :posts) - # # => SELECT ... FROM posts INNER JOIN categories_posts ... INNER JOIN categories ... - # INNER JOIN categories_posts posts_categories_join INNER JOIN posts posts_categories - # Post.joins(categories: {posts: :categories}) - # # => SELECT ... FROM posts INNER JOIN categories_posts ... INNER JOIN categories ... - # INNER JOIN categories_posts posts_categories_join INNER JOIN posts posts_categories - # INNER JOIN categories_posts categories_posts_join INNER JOIN categories categories_posts_2 - # - # If you wish to specify your own custom joins using ActiveRecord::QueryMethods#joins method, those table - # names will take precedence over the eager associations: - # - # Post.joins(:comments).joins("inner join comments ...") - # # => SELECT ... FROM posts INNER JOIN comments_posts ON ... INNER JOIN comments ... - # Post.joins(:comments, :special_comments).joins("inner join comments ...") - # # => SELECT ... FROM posts INNER JOIN comments comments_posts ON ... - # INNER JOIN comments special_comments_posts ... - # INNER JOIN comments ... - # - # Table aliases are automatically truncated according to the maximum length of table identifiers - # according to the specific database. - # - # == Modules - # - # By default, associations will look for objects within the current module scope. Consider: - # - # module MyApplication - # module Business - # class Firm < ActiveRecord::Base - # has_many :clients - # end - # - # class Client < ActiveRecord::Base; end - # end - # end - # - # When <tt>Firm#clients</tt> is called, it will in turn call - # <tt>MyApplication::Business::Client.find_all_by_firm_id(firm.id)</tt>. - # If you want to associate with a class in another module scope, this can be done by - # specifying the complete class name. - # - # module MyApplication - # module Business - # class Firm < ActiveRecord::Base; end - # end - # - # module Billing - # class Account < ActiveRecord::Base - # belongs_to :firm, class_name: "MyApplication::Business::Firm" - # end - # end - # end - # - # == Bi-directional associations - # - # When you specify an association there is usually an association on the associated model - # that specifies the same relationship in reverse. For example, with the following models: - # - # class Dungeon < ActiveRecord::Base - # has_many :traps - # has_one :evil_wizard - # end - # - # class Trap < ActiveRecord::Base - # belongs_to :dungeon - # end - # - # class EvilWizard < ActiveRecord::Base - # belongs_to :dungeon - # end - # - # The +traps+ association on +Dungeon+ and the +dungeon+ association on +Trap+ are - # the inverse of each other and the inverse of the +dungeon+ association on +EvilWizard+ - # is the +evil_wizard+ association on +Dungeon+ (and vice-versa). By default, - # Active Record can guess the inverse of the association based on the name - # of the class. The result is the following: - # - # d = Dungeon.first - # t = d.traps.first - # d.object_id == t.dungeon.object_id # => true - # - # The +Dungeon+ instances +d+ and <tt>t.dungeon</tt> in the above example refer to - # the same in-memory instance since the association matches the name of the class. - # The result would be the same if we added +:inverse_of+ to our model definitions: - # - # class Dungeon < ActiveRecord::Base - # has_many :traps, inverse_of: :dungeon - # has_one :evil_wizard, inverse_of: :dungeon - # end - # - # class Trap < ActiveRecord::Base - # belongs_to :dungeon, inverse_of: :traps - # end - # - # class EvilWizard < ActiveRecord::Base - # belongs_to :dungeon, inverse_of: :evil_wizard - # end - # - # There are limitations to <tt>:inverse_of</tt> support: - # - # * does not work with <tt>:through</tt> associations. - # * does not work with <tt>:polymorphic</tt> associations. - # * for #belongs_to associations #has_many inverse associations are ignored. - # - # For more information, see the documentation for the +:inverse_of+ option. - # - # == Deleting from associations - # - # === Dependent associations - # - # #has_many, #has_one and #belongs_to associations support the <tt>:dependent</tt> option. - # This allows you to specify that associated records should be deleted when the owner is - # deleted. - # - # For example: - # - # class Author - # has_many :posts, dependent: :destroy - # end - # Author.find(1).destroy # => Will destroy all of the author's posts, too - # - # The <tt>:dependent</tt> option can have different values which specify how the deletion - # is done. For more information, see the documentation for this option on the different - # specific association types. When no option is given, the behavior is to do nothing - # with the associated records when destroying a record. - # - # Note that <tt>:dependent</tt> is implemented using Rails' callback - # system, which works by processing callbacks in order. Therefore, other - # callbacks declared either before or after the <tt>:dependent</tt> option - # can affect what it does. - # - # Note that <tt>:dependent</tt> option is ignored for #has_one <tt>:through</tt> associations. - # - # === Delete or destroy? - # - # #has_many and #has_and_belongs_to_many associations have the methods <tt>destroy</tt>, - # <tt>delete</tt>, <tt>destroy_all</tt> and <tt>delete_all</tt>. - # - # For #has_and_belongs_to_many, <tt>delete</tt> and <tt>destroy</tt> are the same: they - # cause the records in the join table to be removed. - # - # For #has_many, <tt>destroy</tt> and <tt>destroy_all</tt> will always call the <tt>destroy</tt> method of the - # record(s) being removed so that callbacks are run. However <tt>delete</tt> and <tt>delete_all</tt> will either - # do the deletion according to the strategy specified by the <tt>:dependent</tt> option, or - # if no <tt>:dependent</tt> option is given, then it will follow the default strategy. - # The default strategy is to do nothing (leave the foreign keys with the parent ids set), except for - # #has_many <tt>:through</tt>, where the default strategy is <tt>delete_all</tt> (delete - # the join records, without running their callbacks). - # - # There is also a <tt>clear</tt> method which is the same as <tt>delete_all</tt>, except that - # it returns the association rather than the records which have been deleted. - # - # === What gets deleted? - # - # There is a potential pitfall here: #has_and_belongs_to_many and #has_many <tt>:through</tt> - # associations have records in join tables, as well as the associated records. So when we - # call one of these deletion methods, what exactly should be deleted? - # - # The answer is that it is assumed that deletion on an association is about removing the - # <i>link</i> between the owner and the associated object(s), rather than necessarily the - # associated objects themselves. So with #has_and_belongs_to_many and #has_many - # <tt>:through</tt>, the join records will be deleted, but the associated records won't. - # - # This makes sense if you think about it: if you were to call <tt>post.tags.delete(Tag.find_by(name: 'food'))</tt> - # you would want the 'food' tag to be unlinked from the post, rather than for the tag itself - # to be removed from the database. - # - # However, there are examples where this strategy doesn't make sense. For example, suppose - # a person has many projects, and each project has many tasks. If we deleted one of a person's - # tasks, we would probably not want the project to be deleted. In this scenario, the delete method - # won't actually work: it can only be used if the association on the join model is a - # #belongs_to. In other situations you are expected to perform operations directly on - # either the associated records or the <tt>:through</tt> association. - # - # With a regular #has_many there is no distinction between the "associated records" - # and the "link", so there is only one choice for what gets deleted. - # - # With #has_and_belongs_to_many and #has_many <tt>:through</tt>, if you want to delete the - # associated records themselves, you can always do something along the lines of - # <tt>person.tasks.each(&:destroy)</tt>. - # - # == Type safety with ActiveRecord::AssociationTypeMismatch - # - # If you attempt to assign an object to an association that doesn't match the inferred - # or specified <tt>:class_name</tt>, you'll get an ActiveRecord::AssociationTypeMismatch. - # - # == Options - # - # All of the association macros can be specialized through options. This makes cases - # more complex than the simple and guessable ones possible. - module ClassMethods - # Specifies a one-to-many association.

So <tt>belongs_to :author</tt> will by default be linked to the Author class, but - # if the real class name is Person, you'll have to specify it with this option. - # [:foreign_key] - # Specify the foreign key used for the association. By default this is guessed to be the name - # of the association with an "_id" suffix. So a class that defines a <tt>belongs_to :person</tt> - # association will use "person_id" as the default <tt>:foreign_key</tt>. Similarly, - # <tt>belongs_to :favorite_person, class_name: "Person"</tt> will use a foreign key - # of "favorite_person_id". - # [:foreign_type] - # Specify the column used to store the associated object's type, if this is a polymorphic - # association. By default this is guessed to be the name of the association with a "_type" - # suffix. So a class that defines a <tt>belongs_to :taggable, polymorphic: true</tt> - # association will use "taggable_type" as the default <tt>:foreign_type</tt>. - # [:primary_key] - # Specify the method that returns the primary key of associated object used for the association. - # By default this is id. - # [:dependent] - # If set to <tt>:destroy</tt>, the associated object is destroyed when this object is. If set to - # <tt>:delete</tt>, the associated object is deleted *without* calling its destroy method. - # This option should not be specified when #belongs_to is used in conjunction with - # a #has_many relationship on another class because of the potential to leave - # orphaned records behind. - # [:counter_cache] - # Caches the number of belonging objects on the associate class through the use of CounterCache::ClassMethods#increment_counter - # and CounterCache::ClassMethods#decrement_counter. The counter cache is incremented when an object of this - # class is created and decremented when it's destroyed. This requires that a column - # named <tt>#{table_name}_count</tt> (such as +comments_count+ for a belonging Comment class) - # is used on the associate class (such as a Post class) - that is the migration for - # <tt>#{table_name}_count</tt> is created on the associate class (such that <tt>Post.comments_count</tt> will - # return the count cached, see note below). You can also specify a custom counter - # cache column by providing a column name instead of a +true+/+false+ value to this - # option (e.g., <tt>counter_cache: :my_custom_counter</tt>.) - # Note: Specifying a counter cache will add it to that model's list of readonly attributes - # using +attr_readonly+. - # [:polymorphic] - # Specify this association is a polymorphic association by passing +true+. - # Note: If you've enabled the counter cache, then you may want to add the counter cache attribute - # to the +attr_readonly+ list in the associated classes (e.g. <tt>class Post; attr_readonly :comments_count; end</tt>). - # [:validate] - # If +false+, don't validate the associated objects when saving the parent object. +false+ by default. - # [:autosave] - # If true, always save the associated object or destroy it if marked for destruction, when - # saving the parent object. - # If false, never save or destroy the associated object. - # By default, only save the associated object if it's a new record. - # - # Note that NestedAttributes::ClassMethods#accepts_nested_attributes_for - # sets <tt>:autosave</tt> to <tt>true</tt>. - # [:touch] - # If true, the associated object will be touched (the updated_at/on attributes set to current time) - # when this record is either saved or destroyed. If you specify a symbol, that attribute - # will be updated with the current time in addition to the updated_at/on attribute. - # Please note that with touching no validation is performed and only the +after_touch+, - # +after_commit+ and +after_rollback+ callbacks are executed. - # [:inverse_of] - # Specifies the name of the #has_one or #has_many association on the associated - # object that is the inverse of this #belongs_to association. Does not work in - # combination with the <tt>:polymorphic</tt> options. - # See ActiveRecord::Associations::ClassMethods's overview on Bi-directional associations for more detail. - # [:optional] - # When set to +true+, the association will not have its presence validated. - # [:required] - # When set to +true+, the association will also have its presence validated. - # This will validate the association itself, not the id. You can use - # +:inverse_of+ to avoid an extra query during validation. - # NOTE: <tt>required</tt> is set to <tt>true</tt> by default and is deprecated. If - # you don't want to have association presence validated, use <tt>optional: true</tt>. - # - # Option examples: - # belongs_to :firm, foreign_key: "client_of" - # belongs_to :person, primary_key: "name", foreign_key: "person_name" - # belongs_to :author, class_name: "Person", foreign_key: "author_id" - # belongs_to :valid_coupon, ->(o) { where "discounts > ?", o.payments_count }, - # class_name: "Coupon", foreign_key: "coupon_id" - # belongs_to :attachable, polymorphic: true - # belongs_to :project, -> { readonly } - # belongs_to :post, counter_cache: true - # belongs_to :comment, touch: true - # belongs_to :company, touch: :employees_last_updated_at - # belongs_to :user, optional: true - def belongs_to(name, scope = nil, options = {}) - reflection = Builder::BelongsTo.build(self, name, scope, options) - Reflection.add_reflection self, name, reflection - end - - # Specifies a many-to-many relationship with another class. This associates two classes via an - # intermediate join table. Unless the join table is explicitly specified as an option, it is - # guessed using the lexical order of the class names. So a join between Developer and Project - # will give the default join table name of "developers_projects" because "D" precedes "P" alphabetically. - # Note that this precedence is calculated using the <tt><</tt> operator for String. This - # means that if the strings are of different lengths, and the strings are equal when compared - # up to the shortest length, then the longer string is considered of higher - # lexical precedence than the shorter one. For example, one would expect the tables "paper_boxes" and "papers" - # to generate a join table name of "papers_paper_boxes" because of the length of the name "paper_boxes", - # but it in fact generates a join table name of "paper_boxes_papers". Be aware of this caveat, and use the - # custom <tt>:join_table</tt> option if you need to. - # If your tables share a common prefix, it will only appear once at the beginning. For example, - # the tables "catalog_categories" and "catalog_products" generate a join table name of "catalog_categories_products". - # - # The join table should not have a primary key or a model associated with it. You must manually generate the - # join table with a migration such as this: - # - # class CreateDevelopersProjectsJoinTable < ActiveRecord::Migration[5.0] - # def change - # create_join_table :developers, :projects + # If your model class is <tt>Project</tt>, then the module is + # named <tt>Project::GeneratedAssociationMethods</tt>. The +GeneratedAssociationMethods+ module is + # included in the model class immediately after the (anonymous) generated attributes methods + # module, meaning an association will override the methods for an attribute with the same name. + # + # == Cardinality and associations + # + # Active Record associations can be used to describe one-to-one, one-to-many and many-to-many + # relationships between models. Each model uses an association to describe its role in + # the relation. The #belongs_to association is always used in the model that has + # the foreign key. + # + # === One-to-one + # + # Use #has_one in the base, and #belongs_to in the associated model. + # + # class Employee < ActiveRecord::Base + # has_one :office + # end + # class Office < ActiveRecord::Base + # belongs_to :employee # foreign key - employee_id + # end + # + # === One-to-many + # + # Use #has_many in the base, and #belongs_to in the associated model. + # + # class Manager < ActiveRecord::Base + # has_many :employees + # end + # class Employee < ActiveRecord::Base + # belongs_to :manager # foreign key - manager_id + # end + # + # === Many-to-many + # + # There are two ways to build a many-to-many relationship. + # + # The first way uses a #has_many association with the <tt>:through</tt> option and a join model, so + # there are two stages of associations. + # + # class Assignment < ActiveRecord::Base + # belongs_to :programmer # foreign key - programmer_id + # belongs_to :project # foreign key - project_id + # end + # class Programmer < ActiveRecord::Base + # has_many :assignments + # has_many :projects, through: :assignments + # end + # class Project < ActiveRecord::Base + # has_many :assignments + # has_many :programmers, through: :assignments + # end + # + # For the second way, use #has_and_belongs_to_many in both models. This requires a join table + # that has no corresponding model or primary key. + # + # class Programmer < ActiveRecord::Base + # has_and_belongs_to_many :projects # foreign keys in the join table + # end + # class Project < ActiveRecord::Base + # has_and_belongs_to_many :programmers # foreign keys in the join table + # end + # + # Choosing which way to build a many-to-many relationship is not always simple. + # If you need to work with the relationship model as its own entity, + # use #has_many <tt>:through</tt>. Use #has_and_belongs_to_many when working with legacy schemas or when + # you never work directly with the relationship itself. + # + # == Is it a #belongs_to or #has_one association? + # + # Both express a 1-1 relationship. The difference is mostly where to place the foreign + # key, which goes on the table for the class declaring the #belongs_to relationship. + # + # class User < ActiveRecord::Base + # # I reference an account. + # belongs_to :account + # end + # + # class Account < ActiveRecord::Base + # # One user references me. + # has_one :user + # end + # + # The tables for these classes could look something like: + # + # CREATE TABLE users ( + # id int NOT NULL auto_increment, + # account_id int default NULL, + # name varchar default NULL, + # PRIMARY KEY (id) + # ) + # + # CREATE TABLE accounts ( + # id int NOT NULL auto_increment, + # name varchar default NULL, + # PRIMARY KEY (id) + # ) + # + # == Unsaved objects and associations + # + # You can manipulate objects and associations before they are saved to the database, but + # there is some special behavior you should be aware of, mostly involving the saving of + # associated objects. + # + # You can set the <tt>:autosave</tt> option on a #has_one, #belongs_to, + # #has_many, or #has_and_belongs_to_many association. Setting it + # to +true+ will _always_ save the members, whereas setting it to +false+ will + # _never_ save the members. More details about <tt>:autosave</tt> option is available at + # AutosaveAssociation. + # + # === One-to-one associations + # + # * Assigning an object to a #has_one association automatically saves that object and + # the object being replaced (if there is one), in order to update their foreign + # keys - except if the parent object is unsaved (<tt>new_record? == true</tt>). + # * If either of these saves fail (due to one of the objects being invalid), an + # ActiveRecord::RecordNotSaved exception is raised and the assignment is + # cancelled. + # * If you wish to assign an object to a #has_one association without saving it, + # use the <tt>#build_association</tt> method (documented below). The object being + # replaced will still be saved to update its foreign key. + # * Assigning an object to a #belongs_to association does not save the object, since + # the foreign key field belongs on the parent. It does not save the parent either. + # + # === Collections + # + # * Adding an object to a collection (#has_many or #has_and_belongs_to_many) automatically + # saves that object, except if the parent object (the owner of the collection) is not yet + # stored in the database. + # * If saving any of the objects being added to a collection (via <tt>push</tt> or similar) + # fails, then <tt>push</tt> returns +false+. + # * If saving fails while replacing the collection (via <tt>association=</tt>), an + # ActiveRecord::RecordNotSaved exception is raised and the assignment is + # cancelled. + # * You can add an object to a collection without automatically saving it by using the + # <tt>collection.build</tt> method (documented below). + # * All unsaved (<tt>new_record? == true</tt>) members of the collection are automatically + # saved when the parent is saved. + # + # == Customizing the query + # + # \Associations are built from <tt>Relation</tt> objects, and you can use the Relation syntax + # to customize them. For example, to add a condition: + # + # class Blog < ActiveRecord::Base + # has_many :published_posts, -> { where(published: true) }, class_name: 'Post' + # end + # + # Inside the <tt>-> { ... }</tt> block you can use all of the usual Relation methods. + # + # === Accessing the owner object + # + # Sometimes it is useful to have access to the owner object when building the query. The owner + # is passed as a parameter to the block. For example, the following association would find all + # events that occur on the user's birthday: + # + # class User < ActiveRecord::Base + # has_many :birthday_events, ->(user) { where(starts_on: user.birthday) }, class_name: 'Event' + # end + # + # Note: Joining, eager loading and preloading of these associations is not fully possible. + # These operations happen before instance creation and the scope will be called with a +nil+ argument. + # This can lead to unexpected behavior and is deprecated. + # + # == Association callbacks + # + # Similar to the normal callbacks that hook into the life cycle of an Active Record object, + # you can also define callbacks that get triggered when you add an object to or remove an + # object from an association collection. + # + # class Project + # has_and_belongs_to_many :developers, after_add: :evaluate_velocity + # + # def evaluate_velocity(developer) + # ... # end # end # - # It's also a good idea to add indexes to each of those columns to speed up the joins process. - # However, in MySQL it is advised to add a compound index for both of the columns as MySQL only - # uses one index per table during the lookup. - # - # Adds the following methods for retrieval and query: - # - # +collection+ is a placeholder for the symbol passed as the +name+ argument, so - # <tt>has_and_belongs_to_many :categories</tt> would add among others <tt>categories.empty?</tt>. - # - # [collection(force_reload = false)] - # Returns an array of all the associated objects. - # An empty array is returned if none are found. - # [collection<<(object, ...)] - # Adds one or more objects to the collection by creating associations in the join table - # (<tt>collection.push</tt> and <tt>collection.concat</tt> are aliases to this method). - # Note that this operation instantly fires update SQL without waiting for the save or update call on the - # parent object, unless the parent object is a new record. - # [collection.delete(object, ...)] - # Removes one or more objects from the collection by removing their associations from the join table. - # This does not destroy the objects. - # [collection.destroy(object, ...)] - # Removes one or more objects from the collection by running destroy on each association in the join table, overriding any dependent option. - # This does not destroy the objects. - # [collection=objects] - # Replaces the collection's content by deleting and adding objects as appropriate. - # [collection_singular_ids] - # Returns an array of the associated objects' ids. - # [collection_singular_ids=ids] - # Replace the collection by the objects identified by the primary keys in +ids+. - # [collection.clear] - # Removes every object from the collection. This does not destroy the objects. - # [collection.empty?] - # Returns +true+ if there are no associated objects. - # [collection.size] - # Returns the number of associated objects. - # [collection.find(id)] - # Finds an associated object responding to the +id+ and that - # meets the condition that it has to be associated with this object. - # Uses the same rules as ActiveRecord::FinderMethods#find. - # [collection.exists?(...)] - # Checks whether an associated object with the given conditions exists. - # Uses the same rules as ActiveRecord::FinderMethods#exists?. - # [collection.build(attributes = {})] - # Returns a new object of the collection type that has been instantiated - # with +attributes+ and linked to this object through the join table, but has not yet been saved. - # [collection.create(attributes = {})] - # Returns a new object of the collection type that has been instantiated - # with +attributes+, linked to this object through the join table, and that has already been - # saved (if it passed the validation). - # - # === Example - # - # A Developer class declares <tt>has_and_belongs_to_many :projects</tt>, which will add: - # * <tt>Developer#projects</tt> - # * <tt>Developer#projects<<</tt> - # * <tt>Developer#projects.delete</tt> - # * <tt>Developer#projects.destroy</tt> - # * <tt>Developer#projects=</tt> - # * <tt>Developer#project_ids</tt> - # * <tt>Developer#project_ids=</tt> - # * <tt>Developer#projects.clear</tt> - # * <tt>Developer#projects.empty?</tt> - # * <tt>Developer#projects.size</tt> - # * <tt>Developer#projects.find(id)</tt> - # * <tt>Developer#projects.exists?(...)</tt> - # * <tt>Developer#projects.build</tt> (similar to <tt>Project.new("developer_id" => id)</tt>) - # * <tt>Developer#projects.create</tt> (similar to <tt>c = Project.new("developer_id" => id); c.save; c</tt>) - # The declaration may include an +options+ hash to specialize the behavior of the association. - # - # === Scopes - # - # You can pass a second argument +scope+ as a callable (i.e. proc or - # lambda) to retrieve a specific set of records or customize the generated - # query when you access the associated collection. - # - # Scope examples: - # has_and_belongs_to_many :projects, -> { includes(:milestones, :manager) } - # has_and_belongs_to_many :categories, ->(category) { - # where("default_category = ?", category.name) - # } - # - # === Extensions - # - # The +extension+ argument allows you to pass a block into a - # has_and_belongs_to_many association. This is useful for adding new - # finders, creators and other factory-type methods to be used as part of - # the association. - # - # Extension examples: - # has_and_belongs_to_many :contractors do + # It's possible to stack callbacks by passing them as an array. Example: + # + # class Project + # has_and_belongs_to_many :developers, + # after_add: [:evaluate_velocity, Proc.new { |p, d| p.shipping_date = Time.now}] + # end + # + # Possible callbacks are: +before_add+, +after_add+, +before_remove+ and +after_remove+. + # + # If any of the +before_add+ callbacks throw an exception, the object will not be + # added to the collection. + # + # Similarly, if any of the +before_remove+ callbacks throw an exception, the object + # will not be removed from the collection. + # + # == Association extensions + # + # The proxy objects that control the access to associations can be extended through anonymous + # modules. This is especially beneficial for adding new finders, creators, and other + # factory-type methods that are only used as part of this association. + # + # class Account < ActiveRecord::Base + # has_many :people do + # def find_or_create_by_name(name) + # first_name, last_name = name.split(" ", 2) + # find_or_create_by(first_name: first_name, last_name: last_name) + # end + # end + # end + # + # person = Account.first.people.find_or_create_by_name("David Heinemeier Hansson") + # person.first_name # => "David" + # person.last_name # => "Heinemeier Hansson" + # + # If you need to share the same extensions between many associations, you can use a named + # extension module. + # + # module FindOrCreateByNameExtension # def find_or_create_by_name(name) # first_name, last_name = name.split(" ", 2) # find_or_create_by(first_name: first_name, last_name: last_name) # end # end # - # === Options - # - # [:class_name] - # Specify the class name of the association. Use it only if that name can't be inferred - # from the association name. So <tt>has_and_belongs_to_many :projects</tt> will by default be linked to the - # Project class, but if the real class name is SuperProject, you'll have to specify it with this option. - # [:join_table] - # Specify the name of the join table if the default based on lexical order isn't what you want. - # <b>WARNING:</b> If you're overwriting the table name of either class, the +table_name+ method - # MUST be declared underneath any #has_and_belongs_to_many declaration in order to work. - # [:foreign_key] - # Specify the foreign key used for the association. By default this is guessed to be the name - # of this class in lower-case and "_id" suffixed. So a Person class that makes - # a #has_and_belongs_to_many association to Project will use "person_id" as the - # default <tt>:foreign_key</tt>. - # [:association_foreign_key] - # Specify the foreign key used for the association on the receiving side of the association. - # By default this is guessed to be the name of the associated class in lower-case and "_id" suffixed. - # So if a Person class makes a #has_and_belongs_to_many association to Project, - # the association will use "project_id" as the default <tt>:association_foreign_key</tt>. - # [:validate] - # If +false+, don't validate the associated objects when saving the parent object. +true+ by default. - # [:autosave] - # If true, always save the associated objects or destroy them if marked for destruction, when - # saving the parent object. - # If false, never save or destroy the associated objects. - # By default, only save associated objects that are new records. - # - # Note that NestedAttributes::ClassMethods#accepts_nested_attributes_for sets - # <tt>:autosave</tt> to <tt>true</tt>. - # - # Option examples: - # has_and_belongs_to_many :projects - # has_and_belongs_to_many :projects, -> { includes(:milestones, :manager) } - # has_and_belongs_to_many :nations, class_name: "Country" - # has_and_belongs_to_many :categories, join_table: "prods_cats" - # has_and_belongs_to_many :categories, -> { readonly } - def has_and_belongs_to_many(name, scope = nil, options = {}, &extension) - if scope.is_a?(Hash) - options = scope - scope = nil + # class Account < ActiveRecord::Base + # has_many :people, -> { extending FindOrCreateByNameExtension } + # end + # + # class Company < ActiveRecord::Base + # has_many :people, -> { extending FindOrCreateByNameExtension } + # end + # + # Some extensions can only be made to work with knowledge of the association's internals. + # Extensions can access relevant state using the following methods (where +items+ is the + # name of the association): + # + # * <tt>record.association(:items).owner</tt> - Returns the object the association is part of. + # * <tt>record.association(:items).reflection</tt> - Returns the reflection object that describes the association. + # * <tt>record.association(:items).target</tt> - Returns the associated object for #belongs_to and #has_one, or + # the collection of associated objects for #has_many and #has_and_belongs_to_many. + # + # However, inside the actual extension code, you will not have access to the <tt>record</tt> as + # above. In this case, you can access <tt>proxy_association</tt>. For example, + # <tt>record.association(:items)</tt> and <tt>record.items.proxy_association</tt> will return + # the same object, allowing you to make calls like <tt>proxy_association.owner</tt> inside + # association extensions. + # + # == Association Join Models + # + # Has Many associations can be configured with the <tt>:through</tt> option to use an + # explicit join model to retrieve the data. This operates similarly to a + # #has_and_belongs_to_many association. The advantage is that you're able to add validations, + # callbacks, and extra attributes on the join model. Consider the following schema: + # + # class Author < ActiveRecord::Base + # has_many :authorships + # has_many :books, through: :authorships + # end + # + # class Authorship < ActiveRecord::Base + # belongs_to :author + # belongs_to :book + # end + # + # @author = Author.first + # @author.authorships.collect { |a| a.book } # selects all books that the author's authorships belong to + # @author.books # selects all books by using the Authorship join model + # + # You can also go through a #has_many association on the join model: + # + # class Firm < ActiveRecord::Base + # has_many :clients + # has_many :invoices, through: :clients + # end + # + # class Client < ActiveRecord::Base + # belongs_to :firm + # has_many :invoices + # end + # + # class Invoice < ActiveRecord::Base + # belongs_to :client + # end + # + # @firm = Firm.first + # @firm.clients.flat_map { |c| c.invoices } # select all invoices for all clients of the firm + # @firm.invoices # selects all invoices by going through the Client join model + # + # Similarly you can go through a #has_one association on the join model: + # + # class Group < ActiveRecord::Base + # has_many :users + # has_many :avatars, through: :users + # end + # + # class User < ActiveRecord::Base + # belongs_to :group + # has_one :avatar + # end + # + # class Avatar < ActiveRecord::Base + # belongs_to :user + # end + # + # @group = Group.first + # @group.users.collect { |u| u.avatar }.compact # select all avatars for all users in the group + # @group.avatars # selects all avatars by going through the User join model. + # + # An important caveat with going through #has_one or #has_many associations on the + # join model is that these associations are *read-only*. For example, the following + # would not work following the previous example: + # + # @group.avatars << Avatar.new # this would work if User belonged_to Avatar rather than the other way around + # @group.avatars.delete(@group.avatars.last) # so would this + # + # == Setting Inverses + # + # If you are using a #belongs_to on the join model, it is a good idea to set the + # <tt>:inverse_of</tt> option on the #belongs_to, which will mean that the following example + # works correctly (where <tt>tags</tt> is a #has_many <tt>:through</tt> association): + # + # @post = Post.first + # @tag = @post.tags.build name: "ruby" + # @tag.save + # + # The last line ought to save the through record (a <tt>Tagging</tt>). This will only work if the + # <tt>:inverse_of</tt> is set: + # + # class Tagging < ActiveRecord::Base + # belongs_to :post + # belongs_to :tag, inverse_of: :taggings + # end + # + # If you do not set the <tt>:inverse_of</tt> record, the association will + # do its best to match itself up with the correct inverse. Automatic + # inverse detection only works on #has_many, #has_one, and + # #belongs_to associations. + # + # Extra options on the associations, as defined in the + # <tt>AssociationReflection::INVALID_AUTOMATIC_INVERSE_OPTIONS</tt> constant, will + # also prevent the association's inverse from being found automatically. + # + # The automatic guessing of the inverse association uses a heuristic based + # on the name of the class, so it may not work for all associations, + # especially the ones with non-standard names. + # + # You can turn off the automatic detection of inverse associations by setting + # the <tt>:inverse_of</tt> option to <tt>false</tt> like so: + # + # class Tagging < ActiveRecord::Base + # belongs_to :tag, inverse_of: false + # end + # + # == Nested \Associations + # + # You can actually specify *any* association with the <tt>:through</tt> option, including an + # association which has a <tt>:through</tt> option itself. For example: + # + # class Author < ActiveRecord::Base + # has_many :posts + # has_many :comments, through: :posts + # has_many :commenters, through: :comments + # end + # + # class Post < ActiveRecord::Base + # has_many :comments + # end + # + # class Comment < ActiveRecord::Base + # belongs_to :commenter + # end + # + # @author = Author.first + # @author.commenters # => People who commented on posts written by the author + # + # An equivalent way of setting up this association this would be: + # + # class Author < ActiveRecord::Base + # has_many :posts + # has_many :commenters, through: :posts + # end + # + # class Post < ActiveRecord::Base + # has_many :comments + # has_many :commenters, through: :comments + # end + # + # class Comment < ActiveRecord::Base + # belongs_to :commenter + # end + # + # When using a nested association, you will not be able to modify the association because there + # is not enough information to know what modification to make. For example, if you tried to + # add a <tt>Commenter</tt> in the example above, there would be no way to tell how to set up the + # intermediate <tt>Post</tt> and <tt>Comment</tt> objects. + # + # == Polymorphic \Associations + # + # Polymorphic associations on models are not restricted on what types of models they + # can be associated with. Rather, they specify an interface that a #has_many association + # must adhere to. + # + # class Asset < ActiveRecord::Base + # belongs_to :attachable, polymorphic: true + # end + # + # class Post < ActiveRecord::Base + # has_many :assets, as: :attachable # The :as option specifies the polymorphic interface to use. + # end + # + # @asset.attachable = @post + # + # This works by using a type column in addition to a foreign key to specify the associated + # record. In the Asset example, you'd need an +attachable_id+ integer column and an + # +attachable_type+ string column. + # + # Using polymorphic associations in combination with single table inheritance (STI) is + # a little tricky. In order for the associations to work as expected, ensure that you + # store the base model for the STI models in the type column of the polymorphic + # association. To continue with the asset example above, suppose there are guest posts + # and member posts that use the posts table for STI. In this case, there must be a +type+ + # column in the posts table. + # + # Note: The <tt>attachable_type=</tt> method is being called when assigning an +attachable+. + # The +class_name+ of the +attachable+ is passed as a String. + # + # class Asset < ActiveRecord::Base + # belongs_to :attachable, polymorphic: true + # + # def attachable_type=(class_name) + # super(class_name.constantize.base_class.to_s) + # end + # end + # + # class Post < ActiveRecord::Base + # # because we store "Post" in attachable_type now dependent: :destroy will work + # has_many :assets, as: :attachable, dependent: :destroy + # end + # + # class GuestPost < Post + # end + # + # class MemberPost < Post + # end + # + # == Caching + # + # All of the methods are built on a simple caching principle that will keep the result + # of the last query around unless specifically instructed not to. The cache is even + # shared across methods to make it even cheaper to use the macro-added methods without + # worrying too much about performance at the first go. + # + # project.milestones # fetches milestones from the database + # project.milestones.size # uses the milestone cache + # project.milestones.empty? # uses the milestone cache + # project.milestones(true).size # fetches milestones from the database + # project.milestones # uses the milestone cache + # + # == Eager loading of associations + # + # Eager loading is a way to find objects of a certain class and a number of named associations. + # It is one of the easiest ways to prevent the dreaded N+1 problem in which fetching 100 + # posts that each need to display their author triggers 101 database queries. Through the + # use of eager loading, the number of queries will be reduced from 101 to 2. + # + # class Post < ActiveRecord::Base + # belongs_to :author + # has_many :comments + # end + # + # Consider the following loop using the class above: + # + # Post.all.each do |post| + # puts "Post: " + post.title + # puts "Written by: " + post.author.name + # puts "Last comment on: " + post.comments.first.created_on + # end + # + # To iterate over these one hundred posts, we'll generate 201 database queries. Let's + # first just optimize it for retrieving the author: + # + # Post.includes(:author).each do |post| + # + # This references the name of the #belongs_to association that also used the <tt>:author</tt> + # symbol. After loading the posts, +find+ will collect the +author_id+ from each one and load + # all of the referenced authors with one query. Doing so will cut down the number of queries + # from 201 to 102. + # + # We can improve upon the situation further by referencing both associations in the finder with: + # + # Post.includes(:author, :comments).each do |post| + # + # This will load all comments with a single query. This reduces the total number of queries + # to 3. In general, the number of queries will be 1 plus the number of associations + # named (except if some of the associations are polymorphic #belongs_to - see below). + # + # To include a deep hierarchy of associations, use a hash: + # + # Post.includes(:author, { comments: { author: :gravatar } }).each do |post| + # + # The above code will load all the comments and all of their associated + # authors and gravatars. You can mix and match any combination of symbols, + # arrays, and hashes to retrieve the associations you want to load. + # + # All of this power shouldn't fool you into thinking that you can pull out huge amounts + # of data with no performance penalty just because you've reduced the number of queries. + # The database still needs to send all the data to Active Record and it still needs to + # be processed. So it's no catch-all for performance problems, but it's a great way to + # cut down on the number of queries in a situation as the one described above. + # + # Since only one table is loaded at a time, conditions or orders cannot reference tables + # other than the main one. If this is the case, Active Record falls back to the previously + # used <tt>LEFT OUTER JOIN</tt> based strategy. For example: + # + # Post.includes([:author, :comments]).where(['comments.approved = ?', true]) + # + # This will result in a single SQL query with joins along the lines of: + # <tt>LEFT OUTER JOIN comments ON comments.post_id = posts.id</tt> and + # <tt>LEFT OUTER JOIN authors ON authors.id = posts.author_id</tt>. Note that using conditions + # like this can have unintended consequences. + # In the above example, posts with no approved comments are not returned at all because + # the conditions apply to the SQL statement as a whole and not just to the association. + # + # You must disambiguate column references for this fallback to happen, for example + # <tt>order: "author.name DESC"</tt> will work but <tt>order: "name DESC"</tt> will not. + # + # If you want to load all posts (including posts with no approved comments), then write + # your own <tt>LEFT OUTER JOIN</tt> query using <tt>ON</tt>: + # + # Post.joins("LEFT OUTER JOIN comments ON comments.post_id = posts.id AND comments.approved = '1'") + # + # In this case, it is usually more natural to include an association which has conditions defined on it: + # + # class Post < ActiveRecord::Base + # has_many :approved_comments, -> { where(approved: true) }, class_name: 'Comment' + # end + # + # Post.includes(:approved_comments) + # + # This will load posts and eager load the +approved_comments+ association, which contains + # only those comments that have been approved. + # + # If you eager load an association with a specified <tt>:limit</tt> option, it will be ignored, + # returning all the associated objects: + # + # class Picture < ActiveRecord::Base + # has_many :most_recent_comments, -> { order('id DESC').limit(10) }, class_name: 'Comment' + # end + # + # Picture.includes(:most_recent_comments).first.most_recent_comments # => returns all associated comments. + # + # Eager loading is supported with polymorphic associations. + # + # class Address < ActiveRecord::Base + # belongs_to :addressable, polymorphic: true + # end + # + # A call that tries to eager load the addressable model + # + # Address.includes(:addressable) + # + # This will execute one query to load the addresses and load the addressables with one + # query per addressable type. + # For example, if all the addressables are either of class Person or Company, then a total + # of 3 queries will be executed. The list of addressable types to load is determined on + # the back of the addresses loaded. This is not supported if Active Record has to fallback + # to the previous implementation of eager loading and will raise ActiveRecord::EagerLoadPolymorphicError. + # The reason is that the parent model's type is a column value so its corresponding table + # name cannot be put in the +FROM+/+JOIN+ clauses of that query. + # + # == Table Aliasing + # + # Active Record uses table aliasing in the case that a table is referenced multiple times + # in a join. If a table is referenced only once, the standard table name is used. The + # second time, the table is aliased as <tt>#{reflection_name}_#{parent_table_name}</tt>. + # Indexes are appended for any more successive uses of the table name. + # + # Post.joins(:comments) + # # => SELECT ... FROM posts INNER JOIN comments ON ... + # Post.joins(:special_comments) # STI + # # => SELECT ... FROM posts INNER JOIN comments ON ... AND comments.type = 'SpecialComment' + # Post.joins(:comments, :special_comments) # special_comments is the reflection name, posts is the parent table name + # # => SELECT ... FROM posts INNER JOIN comments ON ... INNER JOIN comments special_comments_posts + # + # Acts as tree example: + # + # TreeMixin.joins(:children) + # # => SELECT ... FROM mixins INNER JOIN mixins childrens_mixins ... + # TreeMixin.joins(children: :parent) + # # => SELECT ... FROM mixins INNER JOIN mixins childrens_mixins ... + # INNER JOIN parents_mixins ... + # TreeMixin.joins(children: {parent: :children}) + # # => SELECT ...

FROM posts INNER JOIN categories_posts ... INNER JOIN categories ... + # INNER JOIN categories_posts posts_categories_join INNER JOIN posts posts_categories + # INNER JOIN categories_posts categories_posts_join INNER JOIN categories categories_posts_2 + # + # If you wish to specify your own custom joins using ActiveRecord::QueryMethods#joins method, those table + # names will take precedence over the eager associations: + # + # Post.joins(:comments).joins("inner join comments ...") + # # => SELECT ...

FROM posts INNER JOIN comments comments_posts ON ... + # INNER JOIN comments special_comments_posts ... + # INNER JOIN comments ... + # + # Table aliases are automatically truncated according to the maximum length of table identifiers + # according to the specific database. + # + # == Modules + # + # By default, associations will look for objects within the current module scope. Consider: + # + # module MyApplication + # module Business + # class Firm < ActiveRecord::Base + # has_many :clients + # end + # + # class Client < ActiveRecord::Base; end + # end + # end + # + # When <tt>Firm#clients</tt> is called, it will in turn call + # <tt>MyApplication::Business::Client.find_all_by_firm_id(firm.id)</tt>. + # If you want to associate with a class in another module scope, this can be done by + # specifying the complete class name. + # + # module MyApplication + # module Business + # class Firm < ActiveRecord::Base; end + # end + # + # module Billing + # class Account < ActiveRecord::Base + # belongs_to :firm, class_name: "MyApplication::Business::Firm" + # end + # end + # end + # + # == Bi-directional associations + # + # When you specify an association, there is usually an association on the associated model + # that specifies the same relationship in reverse. For example, with the following models: + # + # class Dungeon < ActiveRecord::Base + # has_many :traps + # has_one :evil_wizard + # end + # + # class Trap < ActiveRecord::Base + # belongs_to :dungeon + # end + # + # class EvilWizard < ActiveRecord::Base + # belongs_to :dungeon + # end + # + # The +traps+ association on +Dungeon+ and the +dungeon+ association on +Trap+ are + # the inverse of each other, and the inverse of the +dungeon+ association on +EvilWizard+ + # is the +evil_wizard+ association on +Dungeon+ (and vice-versa). By default, + # Active Record can guess the inverse of the association based on the name + # of the class. The result is the following: + # + # d = Dungeon.first + # t = d.traps.first + # d.object_id == t.dungeon.object_id # => true + # + # The +Dungeon+ instances +d+ and <tt>t.dungeon</tt> in the above example refer to + # the same in-memory instance since the association matches the name of the class. + # The result would be the same if we added +:inverse_of+ to our model definitions: + # + # class Dungeon < ActiveRecord::Base + # has_many :traps, inverse_of: :dungeon + # has_one :evil_wizard, inverse_of: :dungeon + # end + # + # class Trap < ActiveRecord::Base + # belongs_to :dungeon, inverse_of: :traps + # end + # + # class EvilWizard < ActiveRecord::Base + # belongs_to :dungeon, inverse_of: :evil_wizard + # end + # + # There are limitations to <tt>:inverse_of</tt> support: + # + # * does not work with <tt>:through</tt> associations. + # * does not work with <tt>:polymorphic</tt> associations. + # * inverse associations for #belongs_to associations #has_many are ignored. + # + # For more information, see the documentation for the +:inverse_of+ option. + # + # == Deleting from associations + # + # === Dependent associations + # + # #has_many, #has_one, and #belongs_to associations support the <tt>:dependent</tt> option. + # This allows you to specify that associated records should be deleted when the owner is + # deleted. + # + # For example: + # + # class Author + # has_many :posts, dependent: :destroy + # end + # Author.find(1).destroy # => Will destroy all of the author's posts, too + # + # The <tt>:dependent</tt> option can have different values which specify how the deletion + # is done. For more information, see the documentation for this option on the different + # specific association types. When no option is given, the behavior is to do nothing + # with the associated records when destroying a record. + # + # Note that <tt>:dependent</tt> is implemented using Rails' callback + # system, which works by processing callbacks in order. Therefore, other + # callbacks declared either before or after the <tt>:dependent</tt> option + # can affect what it does. + # + # Note that <tt>:dependent</tt> option is ignored for #has_one <tt>:through</tt> associations. + # + # === Delete or destroy? + # + # #has_many and #has_and_belongs_to_many associations have the methods <tt>destroy</tt>, + # <tt>delete</tt>, <tt>destroy_all</tt> and <tt>delete_all</tt>. + # + # For #has_and_belongs_to_many, <tt>delete</tt> and <tt>destroy</tt> are the same: they + # cause the records in the join table to be removed. + # + # For #has_many, <tt>destroy</tt> and <tt>destroy_all</tt> will always call the <tt>destroy</tt> method of the + # record(s) being removed so that callbacks are run. However <tt>delete</tt> and <tt>delete_all</tt> will either + # do the deletion according to the strategy specified by the <tt>:dependent</tt> option, or + # if no <tt>:dependent</tt> option is given, then it will follow the default strategy. + # The default strategy is to do nothing (leave the foreign keys with the parent ids set), except for + # #has_many <tt>:through</tt>, where the default strategy is <tt>delete_all</tt> (delete + # the join records, without running their callbacks). + # + # There is also a <tt>clear</tt> method which is the same as <tt>delete_all</tt>, except that + # it returns the association rather than the records which have been deleted. + # + # === What gets deleted? + # + # There is a potential pitfall here: #has_and_belongs_to_many and #has_many <tt>:through</tt> + # associations have records in join tables, as well as the associated records. So when we + # call one of these deletion methods, what exactly should be deleted? + # + # The answer is that it is assumed that deletion on an association is about removing the + # <i>link</i> between the owner and the associated object(s), rather than necessarily the + # associated objects themselves. So with #has_and_belongs_to_many and #has_many + # <tt>:through</tt>, the join records will be deleted, but the associated records won't. + # + # This makes sense if you think about it: if you were to call <tt>post.tags.delete(Tag.find_by(name: 'food'))</tt> + # you would want the 'food' tag to be unlinked from the post, rather than for the tag itself + # to be removed from the database. + # + # However, there are examples where this strategy doesn't make sense. For example, suppose + # a person has many projects, and each project has many tasks. If we deleted one of a person's + # tasks, we would probably not want the project to be deleted. In this scenario, the delete method + # won't actually work: it can only be used if the association on the join model is a + # #belongs_to. In other situations you are expected to perform operations directly on + # either the associated records or the <tt>:through</tt> association. + # + # With a regular #has_many there is no distinction between the "associated records" + # and the "link", so there is only one choice for what gets deleted. + # + # With #has_and_belongs_to_many and #has_many <tt>:through</tt>, if you want to delete the + # associated records themselves, you can always do something along the lines of + # <tt>person.tasks.each(&:destroy)</tt>. + # + # == Type safety with ActiveRecord::AssociationTypeMismatch + # + # If you attempt to assign an object to an association that doesn't match the inferred + # or specified <tt>:class_name</tt>, you'll get an ActiveRecord::AssociationTypeMismatch. + # + # == Options + # + # All of the association macros can be specialized through options. This makes cases + # more complex than the simple and guessable ones possible. + module ClassMethods + # Specifies a one-to-many association. The following methods for retrieval and query of + # collections of associated objects will be added: + # + # +collection+ is a placeholder for the symbol passed as the +name+ argument, so + # <tt>has_many :clients</tt> would add among others <tt>clients.empty?</tt>. + # + # [collection(force_reload = false)] + # Returns an array of all the associated objects. + # An empty array is returned if none are found. + # [collection<<(object, ...)] + # Adds one or more objects to the collection by setting their foreign keys to the collection's primary key. + # Note that this operation instantly fires update SQL without waiting for the save or update call on the + # parent object, unless the parent object is a new record. + # This will also run validations and callbacks of associated object(s). + # [collection.delete(object, ...)] + # Removes one or more objects from the collection by setting their foreign keys to +NULL+. + # Objects will be in addition destroyed if they're associated with <tt>dependent: :destroy</tt>, + # and deleted if they're associated with <tt>dependent: :delete_all</tt>. + # + # If the <tt>:through</tt> option is used, then the join records are deleted (rather than + # nullified) by default, but you can specify <tt>dependent: :destroy</tt> or + # <tt>dependent: :nullify</tt> to override this. + # [collection.destroy(object, ...)] + # Removes one or more objects from the collection by running <tt>destroy</tt> on + # each record, regardless of any dependent option, ensuring callbacks are run. + # + # If the <tt>:through</tt> option is used, then the join records are destroyed + # instead, not the objects themselves. + # [collection=objects] + # Replaces the collections content by deleting and adding objects as appropriate. If the <tt>:through</tt> + # option is true callbacks in the join models are triggered except destroy callbacks, since deletion is + # direct by default. You can specify <tt>dependent: :destroy</tt> or + # <tt>dependent: :nullify</tt> to override this. + # [collection_singular_ids] + # Returns an array of the associated objects' ids + # [collection_singular_ids=ids] + # Replace the collection with the objects identified by the primary keys in +ids+. This + # method loads the models and calls <tt>collection=</tt>. See above. + # [collection.clear] + # Removes every object from the collection. This destroys the associated objects if they + # are associated with <tt>dependent: :destroy</tt>, deletes them directly from the + # database if <tt>dependent: :delete_all</tt>, otherwise sets their foreign keys to +NULL+. + # If the <tt>:through</tt> option is true no destroy callbacks are invoked on the join models. + # Join models are directly deleted. + # [collection.empty?] + # Returns +true+ if there are no associated objects. + # [collection.size] + # Returns the number of associated objects. + # [collection.find(...)] + # Finds an associated object according to the same rules as ActiveRecord::FinderMethods#find. + # [collection.exists?(...)] + # Checks whether an associated object with the given conditions exists. + # Uses the same rules as ActiveRecord::FinderMethods#exists?. + # [collection.build(attributes = {}, ...)] + # Returns one or more new objects of the collection type that have been instantiated + # with +attributes+ and linked to this object through a foreign key, but have not yet + # been saved. + # [collection.create(attributes = {})] + # Returns a new object of the collection type that has been instantiated + # with +attributes+, linked to this object through a foreign key, and that has already + # been saved (if it passed the validation). *Note*: This only works if the base model + # already exists in the DB, not if it is a new (unsaved) record! + # [collection.create!(attributes = {})] + # Does the same as <tt>collection.create</tt>, but raises ActiveRecord::RecordInvalid + # if the record is invalid. + # + # === Example + # + # A <tt>Firm</tt> class declares <tt>has_many :clients</tt>, which will add: + # * <tt>Firm#clients</tt> (similar to <tt>Client.where(firm_id: id)</tt>) + # * <tt>Firm#clients<<</tt> + # * <tt>Firm#clients.delete</tt> + # * <tt>Firm#clients.destroy</tt> + # * <tt>Firm#clients=</tt> + # * <tt>Firm#client_ids</tt> + # * <tt>Firm#client_ids=</tt> + # * <tt>Firm#clients.clear</tt> + # * <tt>Firm#clients.empty?</tt> (similar to <tt>firm.clients.size == 0</tt>) + # * <tt>Firm#clients.size</tt> (similar to <tt>Client.count "firm_id = #{id}"</tt>) + # * <tt>Firm#clients.find</tt> (similar to <tt>Client.where(firm_id: id).find(id)</tt>) + # * <tt>Firm#clients.exists?(name: 'ACME')</tt> (similar to <tt>Client.exists?(name: 'ACME', firm_id: firm.id)</tt>) + # * <tt>Firm#clients.build</tt> (similar to <tt>Client.new("firm_id" => id)</tt>) + # * <tt>Firm#clients.create</tt> (similar to <tt>c = Client.new("firm_id" => id); c.save; c</tt>) + # * <tt>Firm#clients.create!</tt> (similar to <tt>c = Client.new("firm_id" => id); c.save!</tt>) + # The declaration can also include an +options+ hash to specialize the behavior of the association. + # + # === Scopes + # + # You can pass a second argument +scope+ as a callable (i.e. proc or + # lambda) to retrieve a specific set of records or customize the generated + # query when you access the associated collection. + # + # Scope examples: + # has_many :comments, -> { where(author_id: 1) } + # has_many :employees, -> { joins(:address) } + # has_many :posts, ->(post) { where("max_post_length > ?", post.length) } + # + # === Extensions + # + # The +extension+ argument allows you to pass a block into a has_many + # association. This is useful for adding new finders, creators and other + # factory-type methods to be used as part of the association. + # + # Extension examples: + # has_many :employees do + # def find_or_create_by_name(name) + # first_name, last_name = name.split(" ", 2) + # find_or_create_by(first_name: first_name, last_name: last_name) + # end + # end + # + # === Options + # [:class_name] + # Specify the class name of the association. Use it only if that name can't be inferred + # from the association name. So <tt>has_many :products</tt> will by default be linked + # to the +Product+ class, but if the real class name is +SpecialProduct+, you'll have to + # specify it with this option. + # [:foreign_key] + # Specify the foreign key used for the association. By default this is guessed to be the name + # of this class in lower-case and "_id" suffixed. So a Person class that makes a #has_many + # association will use "person_id" as the default <tt>:foreign_key</tt>. + # [:foreign_type] + # Specify the column used to store the associated object's type, if this is a polymorphic + # association. By default this is guessed to be the name of the polymorphic association + # specified on "as" option with a "_type" suffix. So a class that defines a + # <tt>has_many :tags, as: :taggable</tt> association will use "taggable_type" as the + # default <tt>:foreign_type</tt>. + # [:primary_key] + # Specify the name of the column to use as the primary key for the association. By default this is +id+. + # [:dependent] + # Controls what happens to the associated objects when + # their owner is destroyed. Note that these are implemented as + # callbacks, and Rails executes callbacks in order. Therefore, other + # similar callbacks may affect the <tt>:dependent</tt> behavior, and the + # <tt>:dependent</tt> behavior may affect other callbacks. + # + # * <tt>:destroy</tt> causes all the associated objects to also be destroyed. + # * <tt>:delete_all</tt> causes all the associated objects to be deleted directly from the database (so callbacks will not be executed). + # * <tt>:nullify</tt> causes the foreign keys to be set to +NULL+. Callbacks are not executed. + # * <tt>:restrict_with_exception</tt> causes an exception to be raised if there are any associated records. + # * <tt>:restrict_with_error</tt> causes an error to be added to the owner if there are any associated objects. + # + # If using with the <tt>:through</tt> option, the association on the join model must be + # a #belongs_to, and the records which get deleted are the join records, rather than + # the associated records. + # + # If using <tt>dependent: :destroy</tt> on a scoped association, only the scoped objects are destroyed. + # For example, if a Post model defines + # <tt>has_many :comments, -> { where published: true }, dependent: :destroy</tt> and <tt>destroy</tt> is + # called on a post, only published comments are destroyed. This means that any unpublished comments in the + # database would still contain a foreign key pointing to the now deleted post. + # [:counter_cache] + # This option can be used to configure a custom named <tt>:counter_cache.</tt> You only need this option, + # when you customized the name of your <tt>:counter_cache</tt> on the #belongs_to association. + # [:as] + # Specifies a polymorphic interface (See #belongs_to). + # [:through] + # Specifies an association through which to perform the query. This can be any other type + # of association, including other <tt>:through</tt> associations. Options for <tt>:class_name</tt>, + # <tt>:primary_key</tt> and <tt>:foreign_key</tt> are ignored, as the association uses the + # source reflection. + # + # If the association on the join model is a #belongs_to, the collection can be modified + # and the records on the <tt>:through</tt> model will be automatically created and removed + # as appropriate.
