It cannot find - subclass because all classes are loaded automatically when it needs. - - *Dmitry Vorotilin* - -* When `:name` option is provided to `remove_index`, use it if there is no - index by the conventional name. + *Jan Bernacki* - For example, previously if an index was removed like so - `remove_index :values, column: :value, name: 'a_different_name'` - the generated SQL would not contain the specified index name, - and hence the migration would fail. - Fixes #8858. +* Allow for the name of the schema_migrations table to be configured. - *Ezekiel Smithburg* + *Jerad Phelps* -* Created block to by-pass the prepared statement bindings. - This will allow to compose fragments of large SQL statements to - avoid multiple round-trips between Ruby and the DB. +* Do not add to scope includes values from through associations. + Fixed bug when providing `includes` in through association scope, and fetching targets. Example: - - sql = Post.connection.unprepared_statement do - Post.first.comments.to_sql + class Vendor < ActiveRecord::Base + has_many :relationships, -> { includes(:user) } + has_many :users, through: :relationships end - *Cédric Fabianski* - -* Change the semantics of combining scopes to be the same as combining - class methods which return scopes. For example: - - class User < ActiveRecord::Base - scope :active, -> { where state: 'active' } - scope :inactive, -> { where state: 'inactive' } - end - - class Post < ActiveRecord::Base - def self.active - where state: 'active' - end - - def self.inactive - where state: 'inactive' - end - end - - ### BEFORE ### - - User.where(state: 'active').where(state: 'inactive') - # => SELECT * FROM users WHERE state = 'active' AND state = 'inactive' - - User.active.inactive - # => SELECT * FROM users WHERE state = 'inactive' - - Post.active.inactive - # => SELECT * FROM posts WHERE state = 'active' AND state = 'inactive' + vendor = Vendor.first - ### AFTER ### + # Before - User.active.inactive - # => SELECT * FROM posts WHERE state = 'active' AND state = 'inactive' + vendor.users.to_a # => Raises exception: not found `:user` for `User` - Before this change, invoking a scope would merge it into the current - scope and return the result. `Relation#merge` applies "last where - wins" logic to de-duplicate the conditions, but this lead to - confusing and inconsistent behaviour. This fixes that. + # After - If you really do want the "last where wins" logic, you can opt-in to - it like so: + vendor.users.to_a # => No exception is raised - User.active.merge(User.inactive) - Fixes #7365. + Fixes #12242, #9517, #10240. - *Neeraj Singh* and *Jon Leighton* + *Paul Nikitochkin* -* Expand `#cache_key` to consult all relevant updated timestamps. - - Previously only `updated_at` column was checked, now it will - consult other columns that received updated timestamps on save, - such as `updated_on`. When multiple columns are present it will - use the most recent timestamp. - Fixes #9033. - - *Brendon Murphy* - -* Throw `NotImplementedError` when trying to instantiate `ActiveRecord::Base` or an abstract class. - - *Aaron Weiner* - -* Warn when `rake db:structure:dump` with a mysl database and - `mysqldump` is not in the PATH or fails. - Fixes #9518. - - *Yves Senn* - -* Remove `connection#structure_dump`, which is no longer used. *Yves Senn* - -* Make it possible to execute migrations without a transaction even - if the database adapter supports DDL transactions. - Fixes #9483. +* Type cast json values on write, so that the value is consistent + with reading from the database. Example: - class ChangeEnum < ActiveRecord::Migration - disable_ddl_transaction! - - def up - execute "ALTER TYPE model_size ADD VALUE 'new_value'" - end - end + x = JsonDataType.new tags: {"string" => "foo", :symbol => :bar} - *Yves Senn* + # Before: + x.tags # => {"string" => "foo", :symbol => :bar} -* Assigning "0.0" to a nullable numeric column does not make it dirty. - Fixes #9034. + # After: + x.tags # => {"string" => "foo", "symbol" => "bar"} - Example: + *Severin Schoepke* - product = Product.create price: 0.0 - product.price = '0.0' - product.changed? # => false (this used to return true) - product.changes # => {} (this used to return { price: [0.0, 0.0] }) +* `ActiveRecord::Store` works together with PG `hstore` columns. + Fixes #12452. *Yves Senn* -* Added functionality to unscope relations in a relations chain. For - instance, if you are passed in a chain of relations as follows: +* Fix bug where `ActiveRecord::Store` used a global `Hash` to keep track of + all registered `stored_attributes`. Now every subclass of + `ActiveRecord::Base` has it's own `Hash`. - User.where(name: "John").order('id DESC') + *Yves Senn* - but you want to get rid of order, then this feature allows you to do: +* Save `has_one` association when primary key is manually set. - User.where(name: "John").order('id DESC').unscope(:order) - == User.where(name: "John") + Fixes #12302. - The .unscope() function is more general than the .except() method because - .except() only works on the relation it is acting on. However, .unscope() - works for any relation in the entire relation chain. + *Lauro Caetano* - *John Wang* +* Allow any version of BCrypt when using `has_secure_password`. -* Postgresql timestamp with time zone (timestamptz) datatype now returns a - ActiveSupport::TimeWithZone instance instead of a string + *Mike Perham* - *Troy Kruthoff* +* Sub-query generated for `Relation` passed as array condition did not take in account + bind values and have invalid syntax. -* The `#append` method for collection associations behaves like`<<`. - `#prepend` is not defined and `<<` or `#append` should be used. - Fixes #7364. + Generate sub-query with inline bind values. - *Yves Senn* + Fixes #12586. -* Added support for creating a table via Rails migration generator. - For example, + *Paul Nikitochkin* - rails g migration create_books title:string content:text +* Fix a bug where rake db:structure:load crashed when the path contained + spaces. - will generate a migration that creates a table called books with - the listed attributes, without creating a model. + *Kevin Mook* - *Sammy Larbi* +* `ActiveRecord::QueryMethods#unscope` unscopes negative equality -* Fix bug that raises the wrong exception when the exception handled by PostgreSQL adapter - doesn't respond to `#result`. - Fixes #8617. + Allows you to call `#unscope` on a relation with negative equality + operators, i.e. `Arel::Nodes::NotIn` and `Arel::Nodes::NotEqual` that have + been generated through the use of `where.not`. - *kennyj* + *Eric Hankins* -* Support PostgreSQL specific column types when using `change_table`. - Fixes #9480. +* Raise an exception when model without primary key calls `.find_with_ids`. - Example: + *Shimpei Makimoto* - change_table :authors do |t| - t.hstore :books - t.json :metadata - end +* Make `Relation#empty?` use `exists?` instead of `count`. - *Yves Senn* + *Szymon Nowak* -* Revert 408227d9c5ed7d, 'quote numeric'. This introduced some regressions. +* `rake db:structure:dump` no longer crashes when the port was specified as `Fixnum`. - *Steve Klabnik* + *Kenta Okamoto* -* Fix calculation of `db_runtime` property in - `ActiveRecord::Railties::ControllerRuntime#cleanup_view_runtime`. - Previously, after raising `ActionView::MissingTemplate`, `db_runtime` was - not populated. - Fixes #9215. +* `NullRelation#pluck` takes a list of columns - *Igor Fedoronchuk* + The method signature in `NullRelation` was updated to mimic that in + `Calculations`. -* Do not try to touch invalid (and thus not persisted) parent record - for a `belongs_to :parent, touch: true` association + *Derek Prior* - *Olek Janiszewski* +* `scope_chain` should not be mutated for other reflections. -* Fix when performing an ordered join query. The bug only - affected queries where the order was given with a symbol. - Fixes #9275. + Currently `scope_chain` uses same array for building different + `scope_chain` for different associations. During processing + these arrays are sometimes mutated and because of in-place + mutation the changed `scope_chain` impacts other reflections. - Example: + Fix is to dup the value before adding to the `scope_chain`. - # This will expand the order :name to "authors".name. - Author.joins(:books).where('books.published = 1').order(:name) + Fixes #3882. + *Neeraj Singh* -## Rails 4.0.0.beta1 (February 25, 2013) ## +* Prevent the inversed association from being reloaded on save. -* Fix overriding of attributes by `default_scope` on `ActiveRecord::Base#dup`. + Fixes #9499. - *Hiroshige UMINO* + *Dmitry Polushkin* -* Update queries now use prepared statements. - - *Olli Rissanen* - -* Fixing issue #8345. Now throwing an error when one attempts to touch a - new object that has not yet been persisted. For instance: +* Generate subquery for `Relation` if it passed as array condition for `where` + method. Example: - ball = Ball.new - ball.touch :updated_at # => raises error + # Before + Blog.where('id in (?)', Blog.where(id: 1)) + # => SELECT "blogs".* FROM "blogs" WHERE "blogs"."id" = 1 + # => SELECT "blogs".* FROM "blogs" WHERE (id IN (1)) - It is not until the ball object has been persisted that it can be touched. - This follows the behavior of update_column. + # After + Blog.where('id in (?)', Blog.where(id: 1).select(:id)) + # => SELECT "blogs".* FROM "blogs" + # WHERE "blogs"."id" IN (SELECT "blogs"."id" FROM "blogs" WHERE "blogs"."id" = 1) - *John Wang* + Fixes #12415. -* Preloading ordered `has_many :through` associations no longer applies - invalid ordering to the `:through` association. - Fixes #8663. + *Paul Nikitochkin* - *Yves Senn* +* For missed association exception message + which is raised in `ActiveRecord::Associations::Preloader` class + added owner record class name in order to simplify to find problem code. -* The auto explain feature has been removed. This feature was - activated by configuring `config.active_record.auto_explain_threshold_in_seconds`. - The configuration option was deprecated and has no more effect. + *Paul Nikitochkin* - You can still use `ActiveRecord::Relation#explain` to see the EXPLAIN output for - any given relation. +* `has_and_belongs_to_many` is now transparently implemented in terms of + `has_many :through`. Behavior should remain the same, if not, it is a bug. - *Yves Senn* - -* The `:on` option for `after_commit` and `after_rollback` now - accepts an Array of actions. - Fixes #988. - - Example: - - after_commit :update_cache on: [:create, :update] +* `create_savepoint`, `rollback_to_savepoint` and `release_savepoint` accept + a savepoint name. *Yves Senn* -* Rename related indexes on `rename_table` and `rename_column`. This - does not affect indexes with custom names. +* Make `next_migration_number` accessible for third party generators. *Yves Senn* -* Prevent the creation of indices with too long names, which cause - internal operations to fail (sqlite3 adapter only). The method - `allowed_index_name_length` defines the length limit enforced by - rails. It's value defaults to `index_name_length` but can vary per adapter. - Fixes #8264. +* Objects instantiated using a null relationship will now retain the + attributes of the where clause. - *Yves Senn* + Fixes #11676, #11675, #11376. -* Fixing issue #776. + *Paul Nikitochkin*, *Peter Brown*, *Nthalk* - Memory bloat in transactions is handled by having the transaction hold only - the AR objects which it absolutely needs to know about. These are the AR - objects with callbacks (they need to be updated as soon as something in the - transaction occurs). +* Fixed `ActiveRecord::Associations::CollectionAssociation#find` + when using `has_many` association with `:inverse_of` and finding an array of one element, + it should return an array of one element too. - All other AR objects can be updated lazily by keeping a reference to a - TransactionState object. If an AR object gets inside a transaction, then - the transaction will add its TransactionState to the AR object. When the - user makes a call to some attribute on an AR object (which has no - callbacks) associated with a transaction, the AR object will call the - sync_with_transaction_state method and make sure it is up to date with the - transaction. After it has synced with the transaction state, the AR object - will return the attribute that was requested. + *arthurnn* - Most of the logic in the changes are used to handle multiple transactions, - in which case the AR object has to recursively follow parent pointers of - TransactionState objects. +* Callbacks on has_many should access the in memory parent if a inverse_of is set. - *John Wang* + *arthurnn* -* Descriptive error message when the necessary AR adapter gem was not found. - Fixes #7313. +* `ActiveRecord::ConnectionAdapters.string_to_time` respects + string with timezone (e.g. Wed, 04 Sep 2013 20:30:00 JST). - *Yves Senn* + Fixes #12278. -* Active Record now raises an error when blank arguments are passed to query - methods for which blank arguments do not make sense. + *kennyj* + +* Calling `update_attributes` will now throw an `ArgumentError` whenever it + gets a `nil` argument. More specifically, it will throw an error if the + argument that it gets passed does not respond to to `stringify_keys`. Example: - Post.includes() # => raises error + @my_comment.update_attributes(nil) # => raises ArgumentError *John Wang* -* Simplified type casting code for timezone aware attributes to use the - `in_time_zone` method if it is available. This introduces a subtle change - of behavior when using `Date` instances as they are directly converted to - `ActiveSupport::TimeWithZone` instances without first being converted to - `Time` instances. For example: - - # Rails 3.2 behavior - >> Date.today.to_time.in_time_zone - => Wed, 13 Feb 2013 07:00:00 UTC +00:00 - - # Rails 4.0 behavior - >> Date.today.in_time_zone - => Wed, 13 Feb 2013 00:00:00 UTC +00:00 +* Deprecate `quoted_locking_column` method, which isn't used anywhere. - On the plus side it now behaves the same whether you pass a `String` date - or an actual `Date` instance. For example: - - # Rails 3.2 behavior - >> Date.civil(2013, 2, 13).to_time.in_time_zone - => Wed, 13 Feb 2013 07:00:00 UTC +00:00 - >> Time.zone.parse("2013-02-13") - => Wed, 13 Feb 2013 00:00:00 UTC +00:00 - - # Rails 4.0 behavior - >> Date.civil(2013, 2, 13).in_time_zone - => Wed, 13 Feb 2013 00:00:00 UTC +00:00 - >> "2013-02-13".in_time_zone - => Wed, 13 Feb 2013 00:00:00 UTC +00:00 + *kennyj* - If you need the old behavior you can convert the dates to times manually. - For example: +* Migration dump UUID default functions to schema.rb. - >> Post.new(created_at: Date.today).created_at - => Wed, 13 Feb 2013 00:00:00 UTC +00:00 + Fixes #10751. - >> Post.new(created_at: Date.today.to_time).created_at - => Wed, 13 Feb 2013 07:00:00 UTC +00:00 + *kennyj* - *Andrew White* +* Fixed a bug in `ActiveRecord::Associations::CollectionAssociation#find_by_scan` + when using `has_many` association with `:inverse_of` option and UUID primary key. -* Preloading `has_many :through` associations with conditions won't - cache the `:through` association. This will prevent invalid - subsets to be cached. - Fixes #8423. + Fixes #10450. - Example: + *kennyj* - class User - has_many :posts - has_many :recent_comments, -> { where('created_at > ?', 1.week.ago) }, :through => :posts - end +* ActiveRecord::Base#<=> has been removed. Primary keys may not be in order, + or even be numbers, so sorting by id doesn't make sense. Please use `sort_by` + and specify the attribute you wish to sort with. For example, change: - a_user = User.includes(:recent_comments).first + Post.all.to_a.sort - # This is preloaded. - a_user.recent_comments + to: - # This is not preloaded, fetched now. - a_user.posts + Post.all.to_a.sort_by(&:id) - *Yves Senn* + *Aaron Patterson* -* Don't run `after_commit` callbacks when creating through an association - if saving the record fails. +* Fix: joins association, with defined in the scope block constraints by using several + where constraints and at least of them is not `Arel::Nodes::Equality`, + generates invalid SQL expression. - *James Miller* + Fixes #11963. -* Allow store accessors to be overrided like other attribute methods, e.g.: + *Paul Nikitochkin* - class User < ActiveRecord::Base - store :settings, accessors: [ :color, :homepage ], coder: JSON +* Deprecate the delegation of Array bang methods for associations. + To use them, instead first call `#to_a` on the association to access the + array to be acted on. - def color - super || 'red' - end - end + *Ben Woosley* - *Sergey Nartimov* +* `CollectionAssociation#first`/`#last` (e.g. `has_many`) use a `LIMIT`ed + query to fetch results rather than loading the entire collection. -* Quote numeric values being compared to non-numeric columns. Otherwise, - in some database, the string column values will be coerced to a numeric - allowing 0, 0.0 or false to match any string starting with a non-digit. + *Lann Martin* - Example: +* Make possible to run SQLite rake tasks without the `Rails` constant defined. - App.where(apikey: 0) # => SELECT * FROM users WHERE apikey = '0' + *Damien Mathieu* - *Dylan Smith* +* Allow Relation#from to accept other relations with bind values. -* Schema dumper supports dumping the enabled database extensions to `schema.rb` - (currently only supported by postgresql). + *Ryan Wallace* - *Justin George* +* Fix inserts with prepared statements disabled. -* The database adpters now converts the options passed thought `DATABASE_URL` - environment variable to the proper Ruby types before using. For example, SQLite requires - that the timeout value is an integer, and PostgreSQL requires that the - prepared_statements option is a boolean. These now work as expected: + Fixes #12023. - Example: + *Rafael Mendonça França* - DATABASE_URL=sqlite3://localhost/test_db?timeout=500 - DATABASE_URL=postgresql://localhost/test_db?prepared_statements=false +* Setting a has_one association on a new record no longer causes an empty + transaction. - *Aaron Stone + Rafael Mendonça França* + *Dylan Thacker-Smith* -* `Relation#merge` now only overwrites where values on the LHS of the - merge. Consider: +* Fix `AR::Relation#merge` sometimes failing to preserve `readonly(false)` flag. - left = Person.where(age: [13, 14, 15]) - right = Person.where(age: [13, 14]).where(age: [14, 15]) + *thedarkone* - `left` results in the following SQL: +* Re-use `order` argument pre-processing for `reorder`. - WHERE age IN (13, 14, 15) + *Paul Nikitochkin* - `right` results in the following SQL: +* Fix PredicateBuilder so polymorphic association keys in `where` clause can + accept objects other than direct descendants of `ActiveRecord::Base` (decorated + models, for example). - WHERE age IN (13, 14) AND age IN (14, 15) + *Mikhail Dieterle* - Previously, `left.merge(right)` would result in all but the last - condition being removed: +* PostgreSQL adapter recognizes negative money values formatted with + parentheses (eg. `($1.25) # => -1.25`)). + Fixes #11899. - WHERE age IN (14, 15) + *Yves Senn* - Now it results in the LHS condition(s) for `age` being removed, but - the RHS remains as it is: +* Stop interpreting SQL 'string' columns as :string type because there is no + common STRING datatype in SQL. - WHERE age IN (13, 14) AND age IN (14, 15) + *Ben Woosley* - *Jon Leighton* +* `ActiveRecord::FinderMethods#exists?` returns `true`/`false` in all cases. -* Fix handling of dirty time zone aware attributes + *Xavier Noria* - Previously, when `time_zone_aware_attributes` were enabled, after - changing a datetime or timestamp attribute and then changing it back - to the original value, `changed_attributes` still tracked the - attribute as changed. This caused `[attribute]_changed?` and - `changed?` methods to return true incorrectly. +* Assign inet/cidr attribute with `nil` value for invalid address. Example: - in_time_zone 'Paris' do - order = Order.new - original_time = Time.local(2012, 10, 10) - order.shipped_at = original_time - order.save - order.changed? # => false - - # changing value - order.shipped_at = Time.local(2013, 1, 1) - order.changed? # => true - - # reverting to original value - order.shipped_at = original_time - order.changed? # => false, used to return true - end + record = User.new + record.logged_in_from_ip # is type of an inet or a cidr - *Lilibeth De La Cruz* - -* When `#count` is used in conjunction with `#uniq` we perform `count(:distinct => true)`. - Fixes #6865. - - Example: + # Before: + record.logged_in_from_ip = 'bad ip address' # raise exception - relation.uniq.count # => SELECT COUNT(DISTINCT *) + # After: + record.logged_in_from_ip = 'bad ip address' # do not raise exception + record.logged_in_from_ip # => nil + record.logged_in_from_ip_before_type_cast # => 'bad ip address' - *Yves Senn + Kaspar Schiess* + *Paul Nikitochkin* -* PostgreSQL ranges type support. Includes: int4range, int8range, - numrange, tsrange, tstzrange, daterange +* `add_to_target` now accepts a second optional `skip_callbacks` argument - Ranges can be created with inclusive and exclusive bounds. + If truthy, it will skip the :before_add and :after_add callbacks. - Example: + *Ben Woosley* - create_table :Room do |t| - t.daterange :availability - end +* Fix interactions between `:before_add` callbacks and nested attributes + assignment of `has_many` associations, when the association was not + yet loaded: - Room.create(availability: (Date.today..Float::INFINITY)) - Room.first.availability # => Wed, 19 Sep 2012..Infinity + - A `:before_add` callback was being called when a nested attributes + assignment assigned to an existing record. - One thing to note: Range class does not support exclusive lower - bound. + - Nested Attributes assignment did not affect the record in the + association target when a `:before_add` callback triggered the + loading of the association - *Alexander Grebennik* + *Jörg Schray* -* Added a state instance variable to each transaction. Will allow other objects - to know whether a transaction has been committed or rolled back. +* Allow enable_extension migration method to be revertible. - *John Wang* + *Eric Tipton* -* Collection associations `#empty?` always respects builded records. - Fixes #8879. +* Type cast hstore values on write, so that the value is consistent + with reading from the database. Example: - widget = Widget.new - widget.things.build - widget.things.empty? # => false - - *Yves Senn* - -* Support for PostgreSQL's `ltree` data type. - - *Rob Worley* + x = Hstore.new tags: {"bool" => true, "number" => 5} -* Fix undefined method `to_i` when calling `new` on a scope that uses an - Array; Fix FloatDomainError when setting integer column to NaN. - Fixes #8718, #8734, #8757. - - *Jason Stirk + Tristan Harward* - -* Rename `update_attributes` to `update`, keep `update_attributes` as an alias for `update` method. - This is a soft-deprecation for `update_attributes`, although it will still work without any - deprecation message in 4.0 is recommended to start using `update` since `update_attributes` will be - deprecated and removed in future versions of Rails. - - *Amparo Luna + Guillermo Iguaran* - -* `after_commit` and `after_rollback` now validate the `:on` option and raise an `ArgumentError` - if it is not one of `:create`, `:destroy` or `:update` - - *Pascal Friederich* - -* Improve ways to write `change` migrations, making the old `up` & `down` methods no longer necessary. - - * The methods `drop_table` and `remove_column` are now reversible, as long as the necessary information is given. - The method `remove_column` used to accept multiple column names; instead use `remove_columns` (which is not reversible). - The method `change_table` is also reversible, as long as its block doesn't call `remove`, `change` or `change_default` - - * New method `reversible` makes it possible to specify code to be run when migrating up or down. - See the [Guide on Migration](https://github.com/rails/rails/blob/master/guides/source/migrations.md#using-the-reversible-method) - - * New method `revert` will revert a whole migration or the given block. - If migrating down, the given migration / block is run normally. - See the [Guide on Migration](https://github.com/rails/rails/blob/master/guides/source/migrations.md#reverting-previous-migrations) - - Attempting to revert the methods `execute`, `remove_columns` and `change_column` will now - raise an `IrreversibleMigration` instead of actually executing them without any output. + # Before: + x.tags # => {"bool" => true, "number" => 5} - *Marc-André Lafortune* + # After: + x.tags # => {"bool" => "true", "number" => "5"} -* Serialized attributes can be serialized in integer columns. - Fixes #8575. + *Yves Senn* , *Severin Schoepke* - *Rafael Mendonça França* - -* Keep index names when using `alter_table` with sqlite3. - Fixes #3489. +* Fix multidimensional PG arrays containing non-string items. *Yves Senn* -* Add ability for postgresql adapter to disable user triggers in `disable_referential_integrity`. - Fixes #5523. - - *Gary S. Weaver* - -* Added support for `validates_uniqueness_of` in PostgreSQL array columns. - Fixes #8075. - - *Pedro Padron* - -* Allow int4range and int8range columns to be created in PostgreSQL and properly convert to/from database. - - *Alexey Vasiliev aka leopard* +* Fixes bug when using includes combined with select, the select statement was overwritten. -* Do not log the binding values for binary columns. + Fixes #11773. - *Matthew M. Boedicker* + *Edo Balvers* -* Fix counter cache columns not updated when replacing `has_many :through` - associations. +* Load fixtures from linked folders. - *Matthew Robertson* + *Kassio Borges* -* Recognize migrations placed in directories containing numbers and 'rb'. - Fixes #8492. +* Create a directory for sqlite3 file if not present on the system. - *Yves Senn* - -* Add `ActiveRecord::Base.cache_timestamp_format` class attribute to control - the format of the timestamp value in the cache key.

Any - array that is multi-dimensional must be rectangular (each sub array - must have the same number of elements as its siblings). + This has a huge performance penalty. Because if post has 100k + records and all these 100k records would be loaded in memory + even though the comment id was supplied. - If the `pg_array_parser` gem is available, it will be used when - parsing PostgreSQL's array representation. + Fix is to use in-memory records only if loaded? is true.

Please use `readonly` method + explicitly to mark records as `readonly. + Fixes #10615. - post.attributes # => {"id"=>2, "title"=>"My title", "body"=>"My content", "author"=>"Peter"} - post.update_columns(title: 'New title', author: 'Sebastian') # => true - post.attributes # => {"id"=>2, "title"=>"New title", "body"=>"My content", "author"=>"Sebastian"} + Example: - *Sebastian Martinez + Rafael Mendonça França* + user = User.joins(:todos).select("users.*, todos.title as todos_title").readonly(true).first + user.todos_title = 'clean pet' + user.save! # will raise error -* The migration generator now creates a join table with (commented) indexes every time - the migration name contains the word `join_table`: + *Yves Senn* - rails g migration create_join_table_for_artists_and_musics artist_id:index music_id +* Fix the `:primary_key` option for `has_many` associations. + Fixes #10693. - *Aleksey Magusev* + *Yves Senn* -* Add `add_reference` and `remove_reference` schema statements. Aliases, `add_belongs_to` - and `remove_belongs_to` are acceptable. References are reversible. +* Fix bug where tiny types are incorrectly coerced as boolean when the length is more than 1. - Examples: + Fixes #10620. - # Create a user_id column - add_reference(:products, :user) - # Create a supplier_id, supplier_type columns and appropriate index - add_reference(:products, :supplier, polymorphic: true, index: true) - # Remove polymorphic reference - remove_reference(:products, :supplier, polymorphic: true) + *Aaron Patterson* - *Aleksey Magusev* +* Also support extensions in PostgreSQL 9.1. This feature has been supported since 9.1. -* Add `:default` and `:null` options to `column_exists?`. + *kennyj* - column_exists?(:testings, :taggable_id, :integer, null: false) - column_exists?(:testings, :taggable_type, :string, default: 'Photo') +* Deprecate `ConnectionAdapters::SchemaStatements#distinct`, + as it is no longer used by internals. - *Aleksey Magusev* + *Ben Woosley* -* `ActiveRecord::Relation#inspect` now makes it clear that you are - dealing with a `Relation` object rather than an array:. +* Fix pending migrations error when loading schema and `ActiveRecord::Base.table_name_prefix` + is not blank. - User.where(age: 30).inspect - # => <ActiveRecord::Relation [#<User ...>, #<User ...>, ...]> + Call `assume_migrated_upto_version` on connection to prevent it from first + being picked up in `method_missing`. - User.where(age: 30).to_a.inspect - # => [#<User ...>, #<User ...>] + In the base class, `Migration`, `method_missing` expects the argument to be a + table name, and calls `proper_table_name` on the arguments before sending to + `connection`. If `table_name_prefix` or `table_name_suffix` is used, the schema + version changes to `prefix_version_suffix`, breaking `rake test:prepare`. - The number of records displayed will be limited to 10. + Fixes #10411. - *Brian Cardarella, Jon Leighton & Damien Mathieu* + *Kyle Stevens* -* Add `collation` and `ctype` support to PostgreSQL. These are available for PostgreSQL 8.4 or later. - Example: +* Method `read_attribute_before_type_cast` should accept input as symbol. - development: - adapter: postgresql - host: localhost - database: rails_development - username: foo - password: bar - encoding: UTF8 - collation: ja_JP.UTF8 - ctype: ja_JP.UTF8 + *Neeraj Singh* - *kennyj* +* Confirm a record has not already been destroyed before decrementing counter cache. -* Changed `validates_presence_of` on an association so that children objects - do not validate as being present if they are marked for destruction. This - prevents you from saving the parent successfully and thus putting the parent - in an invalid state. + *Ben Tucker* - *Nick Monje & Brent Wheeldon* +* Fixed a bug in `ActiveRecord#sanitize_sql_hash_for_conditions` in which + `self.class` is an argument to `PredicateBuilder#build_from_hash` + causing `PredicateBuilder` to call non-existent method + `Class#reflect_on_association`. -* `FinderMethods#exists?` now returns `false` with the `false` argument. + *Zach Ohlgren* - *Egor Lynko* +* While removing index if column option is missing then raise IrreversibleMigration exception. -* Added support for specifying the precision of a timestamp in the postgresql - adapter. So, instead of having to incorrectly specify the precision using the - `:limit` option, you may use `:precision`, as intended. For example, in a migration: + Following code should raise `IrreversibleMigration`. But the code was + failing since options is an array and not a hash. def change - create_table :foobars do |t| - t.timestamps precision: 0 + change_table :users do |t| + t.remove_index [:name, :email] end end - *Tony Schneider* - -* Allow `ActiveRecord::Relation#pluck` to accept multiple columns. Returns an - array of arrays containing the typecasted values: - - Person.pluck(:id, :name) - # SELECT people.id, people.name FROM people - # [[1, 'David'], [2, 'Jeremy'], [3, 'Jose']] - - *Jeroen van Ingen & Carlos Antonio da Silva* - -* Improve the derivation of HABTM join table name to take account of nesting. - It now takes the table names of the two models, sorts them lexically and - then joins them, stripping any common prefix from the second table name. - - Some examples: - - Top level models (Category <=> Product) - Old: categories_products - New: categories_products - - Top level models with a global table_name_prefix (Category <=> Product) - Old: site_categories_products - New: site_categories_products - - Nested models in a module without a table_name_prefix method (Admin::Category <=> Admin::Product) - Old: categories_products - New: categories_products - - Nested models in a module with a table_name_prefix method (Admin::Category <=> Admin::Product) - Old: categories_products - New: admin_categories_products + Fix was to check if the options is a Hash before operating on it. - Nested models in a parent model (Catalog::Category <=> Catalog::Product) - Old: categories_products - New: catalog_categories_products + Fixes #10419. - Nested models in different parent models (Catalog::Category <=> Content::Page) - Old: categories_pages - New: catalog_categories_content_pages + *Neeraj Singh* - *Andrew White* +* Do not overwrite manually built records during one-to-one nested attribute assignment -* Move HABTM validity checks to `ActiveRecord::Reflection`. One side effect of - this is to move when the exceptions are raised from the point of declaration - to when the association is built. This is consistant with other association - validity checks. + For one-to-one nested associations, if you build the new (in-memory) + child object yourself before assignment, then the NestedAttributes + module will not overwrite it, e.g.: - *Andrew White* - -* Added `stored_attributes` hash which contains the attributes stored using - `ActiveRecord::Store`. This allows you to retrieve the list of attributes - you've defined. - - class User < ActiveRecord::Base - store :settings, accessors: [:color, :homepage] - end - - User.stored_attributes[:settings] # [:color, :homepage] - - *Joost Baaij & Carlos Antonio da Silva* - -* PostgreSQL default log level is now 'warning', to bypass the noisy notice - messages. You can change the log level using the `min_messages` option - available in your config/database.yml. - - *kennyj* - -* Add uuid datatype support to PostgreSQL adapter. - - *Konstantin Shabanov* - -* Added `ActiveRecord::Migration.check_pending!` that raises an error if - migrations are pending. - - *Richard Schneeman* + class Member < ActiveRecord::Base + has_one :avatar + accepts_nested_attributes_for :avatar -* Added `#destroy!` which acts like `#destroy` but will raise an - `ActiveRecord::RecordNotDestroyed` exception instead of returning `false`. - - *Marc-André Lafortune* - -* Added support to `CollectionAssociation#delete` for passing `fixnum` - or `string` values as record ids. This finds the records responding - to the `id` and executes delete on them. - - class Person < ActiveRecord::Base - has_many :pets + def avatar + super || build_avatar(width: 200) + end end - person.pets.delete("1") # => [#<Pet id: 1>] - person.pets.delete(2, 3) # => [#<Pet id: 2>, #<Pet id: 3>] - - *Francesco Rodriguez* - -* Deprecated most of the 'dynamic finder' methods. All dynamic methods - except for `find_by_...` and `find_by_...!` are deprecated. Here's - how you can rewrite the code: - - * `find_all_by_...` can be rewritten using `where(...)` - * `find_last_by_...` can be rewritten using `where(...).last` - * `scoped_by_...` can be rewritten using `where(...)` - * `find_or_initialize_by_...` can be rewritten using - `where(...).first_or_initialize` - * `find_or_create_by_...` can be rewritten using - `find_or_create_by(...)` or where(...).first_or_create` - * `find_or_create_by_...!` can be rewritten using - `find_or_create_by!(...) or `where(...).first_or_create!` - - The implementation of the deprecated dynamic finders has been moved - to the `activerecord-deprecated_finders` gem. See below for details. - - *Jon Leighton* - -* Deprecated the old-style hash based finder API. This means that - methods which previously accepted "finder options" no longer do. For - example this: - - Post.find(:all, conditions: { comments_count: 10 }, limit: 5) - - Should be rewritten in the new style which has existed since Rails 3: - - Post.where(comments_count: 10).limit(5) - - Note that as an interim step, it is possible to rewrite the above as: - - Post.all.merge(where: { comments_count: 10 }, limit: 5) - - This could save you a lot of work if there is a lot of old-style - finder usage in your application. - - `Relation#merge` now accepts a hash of - options, but they must be identical to the names of the equivalent - finder method. These are mostly identical to the old-style finder - option names, except in the following cases: - - * `:conditions` becomes `:where`. - * `:include` becomes `:includes`. - - The code to implement the deprecated features has been moved out to the - `activerecord-deprecated_finders` gem. This gem is a dependency of Active - Record in Rails 4.0, so the interface works out of the box. It will no - longer be a dependency from Rails 4.1 (you'll need to add it to the - `Gemfile` in 4.1), and will be maintained until Rails 5.0. - - *Jon Leighton* - -* It's not possible anymore to destroy a model marked as read only. - - *Johannes Barre* - -* Added ability to ActiveRecord::Relation#from to accept other ActiveRecord::Relation objects. - - Record.from(subquery) - Record.from(subquery, :a) - - *Radoslav Stankov* - -* Added custom coders support for ActiveRecord::Store. Now you can set - your custom coder like this: - - store :settings, accessors: [ :color, :homepage ], coder: JSON - - *Andrey Voronkov* - -* `mysql` and `mysql2` connections will set `SQL_MODE=STRICT_ALL_TABLES` by - default to avoid silent data loss. This can be disabled by specifying - `strict: false` in your `database.yml`. - - *Michael Pearson* - -* Added default order to `first` to assure consistent results among - different database engines. Introduced `take` as a replacement to - the old behavior of `first`. - - *Marcelo Silveira* - -* Added an `:index` option to automatically create indexes for references - and belongs_to statements in migrations. - - The `references` and `belongs_to` methods now support an `index` - option that receives either a boolean value or an options hash - that is identical to options available to the add_index method: - - create_table :messages do |t| - t.references :person, index: true - end - - Is the same as: - - create_table :messages do |t| - t.references :person - end - add_index :messages, :person_id - - Generators have also been updated to use the new syntax. - - *Joshua Wood* - -* Added `#find_by` and `#find_by!` to mirror the functionality - provided by dynamic finders in a way that allows dynamic input more - easily: - - Post.find_by name: 'Spartacus', rating: 4 - Post.find_by "published_at < ?", 2.weeks.ago - Post.find_by! name: 'Spartacus' - - *Jon Leighton* - -* Added ActiveRecord::Base#slice to return a hash of the given methods with - their names as keys and returned values as values. - - *Guillermo Iguaran* + member = Member.new + member.avatar_attributes = {icon: 'sad'} + member.avatar.width # => 200 -* Deprecate eager-evaluated scopes. - - Don't use this: - - scope :red, where(color: 'red') - default_scope where(color: 'red') - - Use this: - - scope :red, -> { where(color: 'red') } - default_scope { where(color: 'red') } + *Olek Janiszewski* - The former has numerous issues. It is a common newbie gotcha to do - the following: +* fixes bug introduced by #3329. Now, when autosaving associations, + deletions happen before inserts and saves. This prevents a 'duplicate + unique value' database error that would occur if a record being created had + the same value on a unique indexed field as that of a record being destroyed. - scope :recent, where(published_at: Time.now - 2.weeks) + *Johnny Holton* - Or a more subtle variant: +* Handle aliased attributes in ActiveRecord::Relation. - scope :recent, -> { where(published_at: Time.now - 2.weeks) } - scope :recent_red, recent.where(color: 'red') + When using symbol keys, ActiveRecord will now translate aliased attribute names to the actual column name used in the database: - Eager scopes are also very complex to implement within Active - Record, and there are still bugs. For example, the following does - not do what you expect: + With the model - scope :remove_conditions, except(:where) - where(...).remove_conditions # => still has conditions + class Topic + alias_attribute :heading, :title + end - *Jon Leighton* + The call -* Remove IdentityMap + Topic.where(heading: 'The First Topic') - IdentityMap has never graduated to be an "enabled-by-default" feature, due - to some inconsistencies with associations, as described in this commit: + should yield the same result as - https://github.com/rails/rails/commit/302c912bf6bcd0fa200d964ec2dc4a44abe328a6 + Topic.where(title: 'The First Topic') - Hence the removal from the codebase, until such issues are fixed. + This also applies to ActiveRecord::Relation::Calculations calls such as `Model.sum(:aliased)` and `Model.pluck(:aliased)`. - *Carlos Antonio da Silva* + This will not work with SQL fragment strings like `Model.sum('DISTINCT aliased')`. -* Added the schema cache dump feature. + *Godfrey Chan* - `Schema cache dump` feature was implemetend. This feature can dump/load internal state of `SchemaCache` instance - because we want to boot rails more quickly when we have many models. +* Mute `psql` output when running rake db:schema:load. - Usage notes: + *Godfrey Chan* - 1) execute rake task. - RAILS_ENV=production bundle exec rake db:schema:cache:dump - => generate db/schema_cache.dump +* Trigger a save on `has_one association=(associate)` when the associate contents have changed. - 2) add config.active_record.use_schema_cache_dump = true in config/production.rb.

This will add - an error to the model, rather than raising an exception. - - The `:restrict` option is renamed to `:restrict_with_exception` to - make this distinction explicit. - - *Manoj Kumar & Jon Leighton* - -* Added `create_join_table` migration helper to create HABTM join tables. - - create_join_table :products, :categories - # => - # create_table :categories_products, id: false do |td| - # td.integer :product_id, null: false - # td.integer :category_id, null: false - # end - - *Rafael Mendonça França* - -* The primary key is always initialized in the @attributes hash to `nil` (unless - another value has been specified). - - *Aaron Paterson* - -* In previous releases, the following would generate a single query with - an `OUTER JOIN comments`, rather than two separate queries: - - Post.includes(:comments) - .where("comments.name = 'foo'") - - This behaviour relies on matching SQL string, which is an inherently - flawed idea unless we write an SQL parser, which we do not wish to - do. - - Therefore, it is now deprecated. - - To avoid deprecation warnings and for future compatibility, you must - explicitly state which tables you reference, when using SQL snippets: - - Post.includes(:comments) - .where("comments.name = 'foo'") - .references(:comments) - - Note that you do not need to explicitly specify references in the - following cases, as they can be automatically inferred: - - Post.includes(:comments).where(comments: { name: 'foo' }) - Post.includes(:comments).where('comments.name' => 'foo') - Post.includes(:comments).order('comments.name') - - You do not need to worry about this unless you are doing eager - loading. Basically, don't worry unless you see a deprecation warning - or (in future releases) an SQL error due to a missing JOIN. - - *Jon Leighton* - -* Support for the `schema_info` table has been dropped.
