Then, it will go to the DB if it - is not found. This is accomplished by calling +find_by_scan+ in - collection associations whenever +options[:inverse_of]+ is not nil. + Fix #8856. - Fixes #9470. + *Chris Thompson* - *John Wang* - -* `rake db:create` does not change permissions of the MySQL root user. - Fixes #8079. - - *Yves Senn* - -* The length of the `version` column in the `schema_migrations` table - created by the `mysql2` adapter is 191 if the encoding is "utf8mb4". - - The "utf8" encoding in MySQL has support for a maximum of 3 bytes per character, - and only contains characters from the BMP. The recently added - [utf8mb4](http://dev.mysql.com/doc/refman/5.5/en/charset-unicode-utf8mb4.html) - encoding extends the support to four bytes. As of this writing, said encoding - is supported in the betas of the `mysql2` gem. - - Setting the encoding to "utf8mb4" has - [a few implications](http://dev.mysql.com/doc/refman/5.5/en/charset-unicode-upgrading.html). - This change addresses the max length for indexes, which is 191 instead of 255. - - *Xavier Noria* - -* Counter caches on associations will now stay valid when attributes are - updated (not just when records are created or destroyed), for example, - when calling `update_attributes`. The following code now works: - - class Comment < ActiveRecord::Base - belongs_to :post, counter_cache: true - end - - class Post < ActiveRecord::Base - has_many :comments - end - - post = Post.create - comment = Comment.create - - post.comments << comment - post.save.reload.comments_count # => 1 - comment.update_attributes(post_id: nil) - - post.save.reload.comments_count # => 0 - - Updating the id of a `belongs_to` object with the id of a new object will - also keep the count accurate. - - *John Wang* - -* Referencing join tables implicitly was deprecated. There is a - possibility that these deprecation warnings are shown even if you - don't make use of that feature. You can now disable the feature entirely. - Fixes #9712. - - Example: - - # in your configuration - config.active_record.disable_implicit_join_references = true - - # or directly - ActiveRecord::Base.disable_implicit_join_references = true - - *Yves Senn* - -* The `:distinct` option for `Relation#count` is deprecated. You - should use `Relation#distinct` instead. - - Example: - - # Before - Post.select(:author_name).count(distinct: true) - - # After - Post.select(:author_name).distinct.count - - *Yves Senn* - -* Rename `Relation#uniq` to `Relation#distinct`. `#uniq` is still - available as an alias but we encourage to use `#distinct` instead. - Also `Relation#uniq_value` is aliased to `Relation#distinct_value`, - this is a temporary solution and you should migrate to `distinct_value`. - - *Yves Senn* - -* Fix quoting for sqlite migrations using copy_table_contents() with binary - columns. - - These would fail with "SQLite3::SQLException: unrecognized token" because - the column was not being passed to quote() so the data was not quoted - correctly. - - *Matthew M. Boedicker* - -* Promotes `change_column_null` to the migrations API. This macro sets/removes - `NOT NULL` constraints, and accepts an optional argument to replace existing - `NULL`s if needed. The adapters for SQLite, MySQL, PostgreSQL, and (at least) - Oracle, already implement this method. - - *Xavier Noria* - -* Uniqueness validation allows you to pass `:conditions` to limit - the constraint lookup. - - Example: - - validates_uniqueness_of :title, conditions: -> { where('approved = ?', true) } - - *Mattias Pfeiffer + Yves Senn* - -* `connection` is deprecated as an instance method. - This allows end-users to have a `connection` method on their models - without clashing with Active Record internals. - - *Ben Moss* - -* When copying migrations, preserve their magic comments and content encoding. - - *OZAWA Sakuro* - -* Fix `subclass_from_attrs` when `eager_load` is false. 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. - - 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. - - *Ezekiel Smithburg* - -* 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. - - Example: - - sql = Post.connection.unprepared_statement do - Post.first.comments.to_sql - 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' - - ### AFTER ### - - User.active.inactive - # => SELECT * FROM posts WHERE state = 'active' AND state = 'inactive' - - 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. - - If you really do want the "last where wins" logic, you can opt-in to - it like so: - - User.active.merge(User.inactive) - - Fixes #7365. - - *Neeraj Singh* and *Jon Leighton* - -* 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 MySQL 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. - - Example: - - class ChangeEnum < ActiveRecord::Migration - disable_ddl_transaction! - - def up - execute "ALTER TYPE model_size ADD VALUE 'new_value'" - end - end - - *Yves Senn* - -* Assigning "0.0" to a nullable numeric column does not make it dirty. - Fixes #9034. - - Example: - - 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] }) - - *Yves Senn* - -* Added functionality to unscope relations in a relations chain. For - instance, if you are passed in a chain of relations as follows: - - User.where(name: "John").order('id DESC') - - but you want to get rid of order, then this feature allows you to do: - - User.where(name: "John").order('id DESC').unscope(:order) - == User.where(name: "John") - - 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. - - *John Wang* - -* Postgresql timestamp with time zone (timestamptz) datatype now returns a - ActiveSupport::TimeWithZone instance instead of a string - - *Troy Kruthoff* - -* The `#append` method for collection associations behaves like`<<`. - `#prepend` is not defined and `<<` or `#append` should be used. - Fixes #7364. - - *Yves Senn* - -* Added support for creating a table via Rails migration generator. - For example, - - rails g migration create_books title:string content:text - - will generate a migration that creates a table called books with - the listed attributes, without creating a model. - - *Sammy Larbi* - -* Fix bug that raises the wrong exception when the exception handled by PostgreSQL adapter - doesn't respond to `#result`. - Fixes #8617. - - *kennyj* - -* Support PostgreSQL specific column types when using `change_table`. - Fixes #9480. - - Example: - - change_table :authors do |t| - t.hstore :books - t.json :metadata - end - - *Yves Senn* - -* Revert 408227d9c5ed7d, 'quote numeric'. This introduced some regressions. - - *Steve Klabnik* - -* 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. - - *Igor Fedoronchuk* - -* Do not try to touch invalid (and thus not persisted) parent record - for a `belongs_to :parent, touch: true` association - - *Olek Janiszewski* - -* Fix when performing an ordered join query. The bug only - affected queries where the order was given with a symbol. - Fixes #9275. - - Example: - - # This will expand the order :name to "authors".name. - Author.joins(:books).where('books.published = 1').order(:name) - - -## Rails 4.0.0.beta1 (February 25, 2013) ## - -* Fix overriding of attributes by `default_scope` on `ActiveRecord::Base#dup`. - - *Hiroshige UMINO* - -* 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: - - Example: - - ball = Ball.new - ball.touch :updated_at # => raises error - - It is not until the ball object has been persisted that it can be touched. - This follows the behavior of update_column. - - *John Wang* - -* Preloading ordered `has_many :through` associations no longer applies - invalid ordering to the `:through` association. - Fixes #8663. - - *Yves Senn* - -* 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. - - You can still use `ActiveRecord::Relation#explain` to see the EXPLAIN output for - any given relation. - - *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] - - *Yves Senn* - -* Rename related indexes on `rename_table` and `rename_column`. This - does not affect indexes with custom names. - - *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. - - *Yves Senn* - -* Fixing issue #776. - - 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). - - 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. - - 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. - - *John Wang* - -* Descriptive error message when the necessary AR adapter gem was not found. - Fixes #7313. - - *Yves Senn* - -* Active Record now raises an error when blank arguments are passed to query - methods for which blank arguments do not make sense. - - Example: - - Post.includes() # => raises error - - *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 - - 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 - - If you need the old behavior you can convert the dates to times manually. - For example: - - >> Post.new(created_at: Date.today).created_at - => Wed, 13 Feb 2013 00:00:00 UTC +00:00 - - >> Post.new(created_at: Date.today.to_time).created_at - => Wed, 13 Feb 2013 07:00:00 UTC +00:00 - - *Andrew White* - -* Preloading `has_many :through` associations with conditions won't - cache the `:through` association. This will prevent invalid - subsets to be cached. - Fixes #8423. - - Example: - - class User - has_many :posts - has_many :recent_comments, -> { where('created_at > ?', 1.week.ago) }, :through => :posts - end - - a_user = User.includes(:recent_comments).first - - # This is preloaded. - a_user.recent_comments - - # This is not preloaded, fetched now. - a_user.posts - - *Yves Senn* - -* Don't run `after_commit` callbacks when creating through an association - if saving the record fails. - - *James Miller* - -* Allow store accessors to be overrided like other attribute methods, e.g.: - - class User < ActiveRecord::Base - store :settings, accessors: [ :color, :homepage ], coder: JSON - - def color - super || 'red' - end - end - - *Sergey Nartimov* - -* 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. - - Example: - - App.where(apikey: 0) # => SELECT * FROM users WHERE apikey = '0' - - *Dylan Smith* - -* Schema dumper supports dumping the enabled database extensions to `schema.rb` - (currently only supported by postgresql). - - *Justin George* - -* The database adapters 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: - - Example: - - DATABASE_URL=sqlite3://localhost/test_db?timeout=500 - DATABASE_URL=postgresql://localhost/test_db?prepared_statements=false - - *Aaron Stone + Rafael Mendonça França* - -* `Relation#merge` now only overwrites where values on the LHS of the - merge. Consider: - - left = Person.where(age: [13, 14, 15]) - right = Person.where(age: [13, 14]).where(age: [14, 15]) - - `left` results in the following SQL: - - WHERE age IN (13, 14, 15) - - `right` results in the following SQL: - - WHERE age IN (13, 14) AND age IN (14, 15) - - Previously, `left.merge(right)` would result in all but the last - condition being removed: - - WHERE age IN (14, 15) - - Now it results in the LHS condition(s) for `age` being removed, but - the RHS remains as it is: - - WHERE age IN (13, 14) AND age IN (14, 15) - - *Jon Leighton* - -* Fix handling of dirty time zone aware attributes - - 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. - - 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 - - *Lilibeth De La Cruz* - -* When `#count` is used in conjunction with `#uniq` we perform `count(:distinct => true)`. - Fixes #6865. - - Example: - - relation.uniq.count # => SELECT COUNT(DISTINCT *) - - *Yves Senn + Kaspar Schiess* - -* PostgreSQL ranges type support. Includes: int4range, int8range, - numrange, tsrange, tstzrange, daterange - - Ranges can be created with inclusive and exclusive bounds. - - Example: - - create_table :Room do |t| - t.daterange :availability - end - - Room.create(availability: (Date.today..Float::INFINITY)) - Room.first.availability # => Wed, 19 Sep 2012..Infinity - - One thing to note: Range class does not support exclusive lower - bound. - - *Alexander Grebennik* - -* Added a state instance variable to each transaction. Will allow other objects - to know whether a transaction has been committed or rolled back. - - *John Wang* - -* Collection associations `#empty?` always respects built records. - Fixes #8879. - - Example: - - widget = Widget.new - widget.things.build - widget.things.empty? # => false - - *Yves Senn* - -* Support for PostgreSQL's `ltree` data type. - - *Rob Worley* - -* 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. - - *Marc-André Lafortune* - -* Serialized attributes can be serialized in integer columns. - Fixes #8575. - - *Rafael Mendonça França* - -* Keep index names when using `alter_table` with sqlite3. - Fixes #3489. - - *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* - -* Do not log the binding values for binary columns. - - *Matthew M. Boedicker* - -* Fix counter cache columns not updated when replacing `has_many :through` - associations. - - *Matthew Robertson* - -* Recognize migrations placed in directories containing numbers and 'rb'. - Fixes #8492. - - *Yves Senn* - -* Add `ActiveRecord::Base.cache_timestamp_format` class attribute to control - the format of the timestamp value in the cache key. Defaults to `:nsec`. - Fixes #8195. - - *Rafael Mendonça França* - -* Session variables can be set for the `mysql`, `mysql2`, and `postgresql` adapters - in the `variables: <hash>` parameter in `config/database.yml`. The key-value pairs of this - hash will be sent in a `SET key = value` query on new database connections. See also: - http://dev.mysql.com/doc/refman/5.0/en/set-statement.html - http://www.postgresql.org/docs/8.3/static/sql-set.html - - *Aaron Stone* - -* Allow `Relation#where` with no arguments to be chained with new `not` query method. - - Example: - - Developer.where.not(name: 'Aaron') - - *Akira Matsuda* - -* Unscope `update_column(s)` query to ignore default scope. - - When applying `default_scope` to a class with a where clause, using - `update_column(s)` could generate a query that would not properly update - the record due to the where clause from the `default_scope` being applied - to the update query. - - class User < ActiveRecord::Base - default_scope -> { where(active: true) } - end - - user = User.first - user.active = false - user.save! - - user.update_column(:active, true) # => false - - In this situation we want to skip the default_scope clause and just - update the record based on the primary key. With this change: - - user.update_column(:active, true) # => true - - Fixes #8436. - - *Carlos Antonio da Silva* - -* SQLite adapter no longer corrupts binary data if the data contains `%00`. - - *Chris Feist* - -* Fix performance problem with `primary_key` method in PostgreSQL adapter when having many schemas. - Uses `pg_constraint` table instead of `pg_depend` table which has many records in general. - Fixes #8414. - - *kennyj* - -* Do not instantiate intermediate Active Record objects when eager loading. - These records caused `after_find` to run more than expected. - Fixes #3313. - - *Yves Senn* - -* Add STI support to init and building associations. - Allows you to do `BaseClass.new(type: "SubClass")` as well as - `parent.children.build(type: "SubClass")` or `parent.build_child` - to initialize an STI subclass. Ensures that the class name is a - valid class and that it is in the ancestors of the super class - that the association is expecting. - - *Jason Rush* - -* Observers was extracted from Active Record as `rails-observers` gem. - - *Rafael Mendonça França* - -* Ensure that associations take a symbol argument. *Steve Klabnik* - -* Fix dirty attribute checks for `TimeZoneConversion` with nil and blank - datetime attributes. Setting a nil datetime to a blank string should not - result in a change being flagged. - Fixes #8310. - - *Alisdair McDiarmid* - -* Prevent mass assignment to the type column of polymorphic associations when using `build` - Fixes #8265. - - *Yves Senn* - -* Deprecate calling `Relation#sum` with a block. To perform a calculation over - the array result of the relation, use `to_a.sum(&block)`. - - *Carlos Antonio da Silva* - -* Fix postgresql adapter to handle BC timestamps correctly - - HistoryEvent.create!(name: "something", occured_at: Date.new(0) - 5.years) - - *Bogdan Gusiev* - -* When running migrations on Postgresql, the `:limit` option for `binary` and `text` columns is silently dropped. - Previously, these migrations caused sql exceptions, because Postgresql doesn't support limits on these types. - - *Victor Costan* - -* Don't change STI type when calling `ActiveRecord::Base#becomes`. - Add `ActiveRecord::Base#becomes!` with the previous behavior. - - See #3023 for more information. - - *Thomas Hollstegge* - -* `rename_index` can be used inside a `change_table` block. - - change_table :accounts do |t| - t.rename_index :user_id, :account_id - end - - *Jarek Radosz* - -* `#pluck` can be used on a relation with `select` clause. Fix #7551 - - Example: - - Topic.select([:approved, :id]).order(:id).pluck(:id) - - *Yves Senn* - -* Do not create useless database transaction when building `has_one` association. - - Example: - - User.has_one :profile - User.new.build_profile - - *Bogdan Gusiev* - -* `:counter_cache` option for `has_many` associations to support custom named counter caches. - Fixes #7993. - - *Yves Senn* - -* Deprecate the possibility to pass a string as third argument of `add_index`. - Pass `unique: true` instead. - - add_index(:users, :organization_id, unique: true) - - *Rafael Mendonça França* - -* Raise an `ArgumentError` when passing an invalid option to `add_index`. - - *Rafael Mendonça França* - -* Fix `find_in_batches` crashing when IDs are strings and start option is not specified. - - *Alexis Bernard* - -* `AR::Base#attributes_before_type_cast` now returns unserialized values for serialized attributes. - - *Nikita Afanasenko* - -* Use query cache/uncache when using `DATABASE_URL`. - Fixes #6951. - - *kennyj* - -* Fix bug where `update_columns` and `update_column` would not let you update the primary key column. - - *Henrik Nyh* - -* The `create_table` method raises an `ArgumentError` when the primary key column is redefined. - Fixes #6378. - - *Yves Senn* - -* `ActiveRecord::AttributeMethods#[]` raises `ActiveModel::MissingAttributeError` - error if the given attribute is missing. Fixes #5433. - - class Person < ActiveRecord::Base - belongs_to :company - end - - # Before: - person = Person.select('id').first - person[:name] # => nil - person.name # => ActiveModel::MissingAttributeError: missing_attribute: name - person[:company_id] # => nil - person.company # => nil - - # After: - person = Person.select('id').first - person[:name] # => ActiveModel::MissingAttributeError: missing_attribute: name - person.name # => ActiveModel::MissingAttributeError: missing_attribute: name - person[:company_id] # => ActiveModel::MissingAttributeError: missing_attribute: company_id - person.company # => ActiveModel::MissingAttributeError: missing_attribute: company_id - - *Francesco Rodriguez* - -* Small binary fields use the `VARBINARY` MySQL type, instead of `TINYBLOB`. - - *Victor Costan* - -* Decode URI encoded attributes on database connection URLs. - - *Shawn Veader* - -* Add `find_or_create_by`, `find_or_create_by!` and - `find_or_initialize_by` methods to `Relation`. - - These are similar to the `first_or_create` family of methods, but - the behaviour when a record is created is slightly different: - - User.where(first_name: 'Penélope').first_or_create - - will execute: - - User.where(first_name: 'Penélope').create - - Causing all the `create` callbacks to execute within the context of - the scope. This could affect queries that occur within callbacks. - - User.find_or_create_by(first_name: 'Penélope') - - will execute: - - User.create(first_name: 'Penélope') - - Which obviously does not affect the scoping of queries within - callbacks. - - The `find_or_create_by` version also reads better, frankly. - - If you need to add extra attributes during create, you can do one of: - - User.create_with(active: true).find_or_create_by(first_name: 'Jon') - User.find_or_create_by(first_name: 'Jon') { |u| u.active = true } - - The `first_or_create` family of methods have been nodoc'ed in favour - of this API. They may be deprecated in the future but their - implementation is very small and it's probably not worth putting users - through lots of annoying deprecation warnings. - - *Jon Leighton* - -* Fix bug with presence validation of associations. Would incorrectly add duplicated errors - when the association was blank. Bug introduced in 1fab518c6a75dac5773654646eb724a59741bc13. - - *Scott Willson* - -* Fix bug where sum(expression) returns string '0' for no matching records. - Fixes #7439 - - *Tim Macfarlane* - -* PostgreSQL adapter correctly fetches default values when using multiple schemas and domains in a db. Fixes #7914 - - *Arturo Pie* - -* Learn ActiveRecord::QueryMethods#order work with hash arguments - - When symbol or hash passed we convert it to Arel::Nodes::Ordering. - If we pass invalid direction(like name: :DeSc) ActiveRecord::QueryMethods#order will raise an exception - - User.order(:name, email: :desc) - # SELECT "users".* FROM "users" ORDER BY "users"."name" ASC, "users"."email" DESC - - *Tima Maslyuchenko* - -* Rename `ActiveRecord::Fixtures` class to `ActiveRecord::FixtureSet`. - Instances of this class normally hold a collection of fixtures (records) - loaded either from a single YAML file, or from a file and a folder - with the same name. This change make the class name singular and makes - the class easier to distinguish from the modules like - `ActiveRecord::TestFixtures`, which operates on multiple fixture sets, - or `DelegatingFixtures`, `::Fixtures`, etc., - and from the class `ActiveRecord::Fixture`, which corresponds to a single - fixture. - - *Alexey Muranov* - -* The postgres adapter now supports tables with capital letters. - Fixes #5920. - - *Yves Senn* - -* `CollectionAssociation#count` returns `0` without querying if the - parent record is not persisted. - - Before: - - person.pets.count - # SELECT COUNT(*) FROM "pets" WHERE "pets"."person_id" IS NULL - # => 0 - - After: - - person.pets.count - # fires without sql query - # => 0 - - *Francesco Rodriguez* - -* Fix `reset_counters` crashing on `has_many :through` associations. - Fixes #7822. - - *lulalala* - -* Support for partial inserts. - - When inserting new records, only the fields which have been changed - from the defaults will actually be included in the INSERT statement. - The other fields will be populated by the database. - - This is more efficient, and also means that it will be safe to - remove database columns without getting subsequent errors in running - app processes (so long as the code in those processes doesn't - contain any references to the removed column). - - The `partial_updates` configuration option is now renamed to - `partial_writes` to reflect the fact that it now impacts both inserts - and updates. - - *Jon Leighton* - -* Allow before and after validations to take an array of lifecycle events - - *John Foley* - -* Support for specifying transaction isolation level - - If your database supports setting the isolation level for a transaction, you can set - it like so: - - Post.transaction(isolation: :serializable) do - # ... - end - - Valid isolation levels are: - - * `:read_uncommitted` - * `:read_committed` - * `:repeatable_read` - * `:serializable` - - You should consult the documentation for your database to understand the - semantics of these different levels: - - * http://www.postgresql.org/docs/9.1/static/transaction-iso.html - * https://dev.mysql.com/doc/refman/5.0/en/set-transaction.html - - An `ActiveRecord::TransactionIsolationError` will be raised if: - - * The adapter does not support setting the isolation level - * You are joining an existing open transaction - * You are creating a nested (savepoint) transaction - - The mysql, mysql2 and postgresql adapters support setting the transaction - isolation level. However, support is disabled for mysql versions below 5, - because they are affected by a bug (http://bugs.mysql.com/bug.php?id=39170) - which means the isolation level gets persisted outside the transaction. - - *Jon Leighton* - -* `ActiveModel::ForbiddenAttributesProtection` is included by default - in Active Record models. Check the docs of `ActiveModel::ForbiddenAttributesProtection` - for more details. - - *Guillermo Iguaran* - -* Remove integration between Active Record and - `ActiveModel::MassAssignmentSecurity`, `protected_attributes` gem - should be added to use `attr_accessible`/`attr_protected`. Mass - assignment options has been removed from all the AR methods that - used it (ex. `AR::Base.new`, `AR::Base.create`, `AR::Base#update_attributes`, etc). - - *Guillermo Iguaran* - -* Fix the return of querying with an empty hash. - Fixes #6971. - - User.where(token: {}) - - Before: - - #=> SELECT * FROM users; - - After: - - #=> SELECT * FROM users WHERE 1=0; - - *Damien Mathieu* - -* Fix creation of through association models when using `collection=[]` - on a `has_many :through` association from an unsaved model. - Fixes #7661. - - *Ernie Miller* - -* Explain only normal CRUD sql (select / update / insert / delete). - Fix problem that explains unexplainable sql. - Closes #7544 #6458. - - *kennyj* - -* You can now override the generated accessor methods for stored attributes - and reuse the original behavior with `read_store_attribute` and `write_store_attribute`, - which are counterparts to `read_attribute` and `write_attribute`. - - *Matt Jones* - -* Accept `belongs_to` (including polymorphic) association keys in queries. - - The following queries are now equivalent: - - Post.where(author: author) - Post.where(author_id: author) - - PriceEstimate.where(estimate_of: treasure) - PriceEstimate.where(estimate_of_type: 'Treasure', estimate_of_id: treasure) - - *Peter Brown* - -* Use native `mysqldump` command instead of `structure_dump` method - when dumping the database structure to a sql file. Fixes #5547. - - *kennyj* - -* PostgreSQL inet and cidr types are converted to `IPAddr` objects. - - *Dan McClain* - -* PostgreSQL array type support. Any datatype can be used to create an - array column, with full migration and schema dumper support. - - To declare an array column, use the following syntax: - - create_table :table_with_arrays do |t| - t.integer :int_array, array: true - # integer[] - t.integer :int_array, array: true, length: 2 - # smallint[] - t.string :string_array, array: true, length: 30 - # char varying(30)[] - end - - This respects any other migration detail (limits, defaults, etc). - Active Record will serialize and deserialize the array columns on - their way to and from the database. - - One thing to note: PostgreSQL does not enforce any limits on the - number of elements, and any array can be multi-dimensional. Any - array that is multi-dimensional must be rectangular (each sub array - must have the same number of elements as its siblings). - - If the `pg_array_parser` gem is available, it will be used when - parsing PostgreSQL's array representation. - - *Dan McClain* - -* Attribute predicate methods, such as `article.title?`, will now raise - `ActiveModel::MissingAttributeError` if the attribute being queried for - truthiness was not read from the database, instead of just returning `false`. - - *Ernie Miller* - -* `ActiveRecord::SchemaDumper` uses Ruby 1.9 style hash, which means that the - schema.rb file will be generated using this new syntax from now on. - - *Konstantin Shabanov* - -* Map interval with precision to string datatype in PostgreSQL. Fixes #7518. - - *Yves Senn* - -* Fix eagerly loading associations without primary keys. Fixes #4976. - - *Kelley Reynolds* - -* Rails now raise an exception when you're trying to run a migration that has an invalid - file name. Only lower case letters, numbers, and '_' are allowed in migration's file name. - Please see #7419 for more details. - - *Jan Bernacki* - -* Fix bug when calling `store_accessor` multiple times. - Fixes #7532. - - *Matt Jones* - -* Fix store attributes that show the changes incorrectly. - Fixes #7532. - - *Matt Jones* - -* Fix `ActiveRecord::Relation#pluck` when columns or tables are reserved words. - - *Ian Lesperance* - -* Allow JSON columns to be created in PostgreSQL and properly encoded/decoded. - to/from database. - - *Dickson S. Guedes* - -* Fix time column type casting for invalid time string values to correctly return `nil`. - - *Adam Meehan* - -* Allow to pass Symbol or Proc into `:limit` option of #accepts_nested_attributes_for. - - *Mikhail Dieterle* - -* ActiveRecord::SessionStore has been extracted from Active Record as `activerecord-session_store` - gem. Please read the `README.md` file on the gem for the usage. - - *Prem Sichanugrist* - -* Fix `reset_counters` when there are multiple `belongs_to` association with the - same foreign key and one of them have a counter cache. - Fixes #5200. - - *Dave Desrochers* - -* `serialized_attributes` and `_attr_readonly` become class method only. Instance reader methods are deprecated. +* Abort a rake task when missing db/structure.sql like `db:schema:load` task. *kennyj* -* Round usec when comparing timestamp attributes in the dirty tracking. - Fixes #6975. - - *kennyj* - -* Use inversed parent for first and last child of `has_many` association. - - *Ravil Bayramgalin* - -* Fix `Column.microseconds` and `Column.fast_string_to_time` to avoid converting - timestamp seconds to a float, since it occasionally results in inaccuracies - with microsecond-precision times. Fixes #7352. - - *Ari Pollak* - -* Fix AR#dup to nullify the validation errors in the dup'ed object. Previously the original - and the dup'ed object shared the same errors. - - *Christian Seiler* - -* Raise `ArgumentError` if list of attributes to change is empty in `update_all`. - - *Roman Shatsov* - -* Fix AR#create to return an unsaved record when AR::RecordInvalid is - raised. Fixes #3217. - - *Dave Yeu* - -* Fixed table name prefix that is generated in engines for namespaced models. - - *Wojciech Wnętrzak* - -* Make sure `:environment` task is executed before `db:schema:load` or `db:structure:load`. - Fixes #4772. - - *Seamus Abshere* - -* Allow Relation#merge to take a proc. - - This was requested by DHH to allow creating of one's own custom - association macros. - - For example: - - module Commentable - def has_many_comments(extra) - has_many :comments, -> { where(:foo).merge(extra) } - end - end - - class Post < ActiveRecord::Base - extend Commentable - has_many_comments -> { where(:bar) } - end - - *Jon Leighton* - -* Add CollectionProxy#scope. - - This can be used to get a Relation from an association. - - Previously we had a #scoped method, but we're deprecating that for - AR::Base, so it doesn't make sense to have it here. - - This was requested by DHH, to facilitate code like this: - - Project.scope.order('created_at DESC').page(current_page).tagged_with(@tag).limit(5).scoping do - @topics = @project.topics.scope - @todolists = @project.todolists.scope - @attachments = @project.attachments.scope - @documents = @project.documents.scope - end - - *Jon Leighton* - -* Add `Relation#load`. - - This method explicitly loads the records and then returns `self`. - - Rather than deciding between "do I want an array or a relation?", - most people are actually asking themselves "do I want to eager load - or lazy load?" Therefore, this method provides a way to explicitly - eager-load without having to switch from a `Relation` to an array. - - Example: - - @posts = Post.where(published: true).load - - *Jon Leighton* - -* `Relation#order`: make new order prepend old one. - - User.order("name asc").order("created_at desc") - # SELECT * FROM users ORDER BY created_at desc, name asc - - This also affects order defined in `default_scope` or any kind of associations. - - *Bogdan Gusiev* - -* `Model.all` now returns an `ActiveRecord::Relation`, rather than an - array of records. Use `Relation#to_a` if you really want an array. - - In some specific cases, this may cause breakage when upgrading. - However in most cases the `ActiveRecord::Relation` will just act as a - lazy-loaded array and there will be no problems. - - Note that calling `Model.all` with options (e.g. - `Model.all(conditions: '...')` was already deprecated, but it will - still return an array in order to make the transition easier. - - `Model.scoped` is deprecated in favour of `Model.all`. - - `Relation#all` still returns an array, but is deprecated (since it - would serve no purpose if we made it return a `Relation`). - - *Jon Leighton* - -* `:finder_sql` and `:counter_sql` options on collection associations - are deprecated. Please transition to using scopes. - - *Jon Leighton* - -* `:insert_sql` and `:delete_sql` options on `has_and_belongs_to_many` - associations are deprecated. Please transition to using `has_many - :through`. - - *Jon Leighton* - -* Added `#update_columns` method which updates the attributes from - the passed-in hash without calling save, hence skipping validations and - callbacks. `ActiveRecordError` will be raised when called on new objects - or when at least one of the attributes is marked as read only. - - 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"} - - *Sebastian Martinez + Rafael Mendonça França* - -* The migration generator now creates a join table with (commented) indexes every time - the migration name contains the word `join_table`: - - rails g migration create_join_table_for_artists_and_musics artist_id:index music_id - - *Aleksey Magusev* - -* Add `add_reference` and `remove_reference` schema statements. Aliases, `add_belongs_to` - and `remove_belongs_to` are acceptable. References are reversible. - - Examples: - - # 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) - - *Aleksey Magusev* - -* Add `:default` and `:null` options to `column_exists?`. - - column_exists?(:testings, :taggable_id, :integer, null: false) - column_exists?(:testings, :taggable_type, :string, default: 'Photo') - - *Aleksey Magusev* - -* `ActiveRecord::Relation#inspect` now makes it clear that you are - dealing with a `Relation` object rather than an array:. - - User.where(age: 30).inspect - # => <ActiveRecord::Relation [#<User ...>, #<User ...>, ...]> - - User.where(age: 30).to_a.inspect - # => [#<User ...>, #<User ...>] - - The number of records displayed will be limited to 10. - - *Brian Cardarella, Jon Leighton & Damien Mathieu* - -* Add `collation` and `ctype` support to PostgreSQL. These are available for PostgreSQL 8.4 or later. - Example: - - development: - adapter: postgresql - host: localhost - database: rails_development - username: foo - password: bar - encoding: UTF8 - collation: ja_JP.UTF8 - ctype: ja_JP.UTF8 - - *kennyj* - -* 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. - - *Nick Monje & Brent Wheeldon* - -* `FinderMethods#exists?` now returns `false` with the `false` argument. - - *Egor Lynko* - -* 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: - - def change - create_table :foobars do |t| - t.timestamps precision: 0 - 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 - - Nested models in a parent model (Catalog::Category <=> Catalog::Product) - Old: categories_products - New: catalog_categories_products - - Nested models in different parent models (Catalog::Category <=> Content::Page) - Old: categories_pages - New: catalog_categories_content_pages - - *Andrew White* - -* 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 consistent with other association - validity checks. - - *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* - -* 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 - 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* - -* 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') } - - The former has numerous issues. It is a common newbie gotcha to do - the following: - - scope :recent, where(published_at: Time.now - 2.weeks) - - Or a more subtle variant: - - scope :recent, -> { where(published_at: Time.now - 2.weeks) } - scope :recent_red, recent.where(color: 'red') - - 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: - - scope :remove_conditions, except(:where) - where(...).remove_conditions # => still has conditions - - *Jon Leighton* - -* Remove IdentityMap - - IdentityMap has never graduated to be an "enabled-by-default" feature, due - to some inconsistencies with associations, as described in this commit: - - https://github.com/rails/rails/commit/302c912bf6bcd0fa200d964ec2dc4a44abe328a6 - - Hence the removal from the codebase, until such issues are fixed. - - *Carlos Antonio da Silva* - -* Added the schema cache dump feature. - - `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. - - Usage notes: - - 1) execute rake task. - RAILS_ENV=production bundle exec rake db:schema:cache:dump - => generate db/schema_cache.dump - - 2) add config.active_record.use_schema_cache_dump = true in config/production.rb.
