Fixes #7516. - - *Yves Senn* - -* Fixed `columns_for_distinct` of postgresql adapter to work correctly - with orders without sort direction modifiers. - - *Nikolay Kondratyev* - -* PostgreSQL `reset_pk_sequence!` respects schemas. Fixes #14719. - - *Yves Senn* - -* Keep PostgreSQL `hstore` and `json` attributes as `Hash` in `@attributes`. - Fixes duplication in combination with `store_accessor`. - - Fixes #15369. - - *Yves Senn* - -* `rake railties:install:migrations` respects the order of railties. - - *Arun Agrawal* - -* Fix redefine a has_and_belongs_to_many inside inherited class - Fixing regression case, where redefining the same has_an_belongs_to_many - definition into a subclass would raise. - - Fixes #14983. - - *arthurnn* - -* Fix has_and_belongs_to_many public reflection. - When defining a has_and_belongs_to_many, internally we convert that to two has_many. - But as `reflections` is a public API, people expect to see the right macro. - - Fixes #14682. - - *arthurnn* +* `eager_load` preserves readonly flag for associations. -* Fixed serialization for records with an attribute named `format`. + Closes #15853. - Fixes #15188. + *Takashi Kokubun* - *Godfrey Chan* +* Provide `:touch` option to `save()` to accommodate saving without updating + timestamps. -* When a `group` is set, `sum`, `size`, `average`, `minimum` and `maximum` - on a NullRelation should return a Hash. + Fixes #18202. - *Kuldeep Aggarwal* + *Dan Olson* -* Fixed serialized fields returning serialized data after being updated with - `update_column`. +* Provide a more helpful error message when an unsupported class is passed to + `serialize`. - *Simon Hørup Eskildsen* - -* Fixed polymorphic eager loading when using a String as foreign key. - - Fixes #14734. - - *Lauro Caetano* - -* Change belongs_to touch to be consistent with timestamp updates - - If a model is set up with a belongs_to: touch relationship the parent - record will only be touched if the record was modified. This makes it - consistent with timestamp updating on the record itself. - - *Brock Trappitt* - -* Fixed the inferred table name of a has_and_belongs_to_many auxiliar - table inside a schema. - - Fixes #14824 - - *Eric Chahin* - -* Remove unused `:timestamp` type. Transparently alias it to `:datetime` - in all cases. Fixes inconsistencies when column types are sent outside of - `ActiveRecord`, such as for XML Serialization. + Fixes #18224. *Sean Griffin* -* Fix bug that added `table_name_prefix` and `table_name_suffix` to - extension names in PostgreSQL when migrating. - - *Joao Carlos* - -* The `:index` option in migrations, which previously was only available for - `references`, now works with any column types. - - *Marc Schütz* - -* Add support for counter name to be passed as parameter on `CounterCache::ClassMethods#reset_counters`. - - *jnormore* - -* Restrict deletion of record when using `delete_all` with `uniq`, `group`, `having` - or `offset`. - - In these cases the generated query ignored them and that caused unintended - records to be deleted. - - Fixes #11985. - - *Leandro Facchinetti* - -* Floats with limit >= 25 that get turned into doubles in MySQL no longer have - their limit dropped from the schema. - - Fixes #14135. - - *Aaron Nelson* - -* Fix how to calculate associated class name when using namespaced has_and_belongs_to_many - association. - - Fixes #14709. - - *Kassio Borges* - -* `ActiveRecord::Relation::Merger#filter_binds` now compares equivalent symbols and - strings in column names as equal. - - This fixes a rare case in which more bind values are passed than there are - placeholders for them in the generated SQL statement, which can make PostgreSQL - throw a `StatementInvalid` exception. - - *Nat Budin* - -* Fix `stored_attributes` to correctly merge the details of stored - attributes defined in parent classes. - - Fixes #14672. - - *Brad Bennett*, *Jessica Yao*, *Lakshmi Parthasarathy* - -* `change_column_default` allows `[]` as argument to `change_column_default`. - - Fixes #11586. - - *Yves Senn* - -* Handle `name` and `"char"` column types in the PostgreSQL adapter. - - `name` and `"char"` are special character types used internally by - PostgreSQL and are used by internal system catalogs. These field types - can sometimes show up in structure-sniffing queries that feature internal system - structures or with certain PostgreSQL extensions. - - *J Smith*, *Yves Senn* - -* Fix `PostgreSQLAdapter::OID::Float#type_cast` to convert Infinity and - NaN PostgreSQL values into a native Ruby `Float::INFINITY` and `Float::NAN` - - Before: - - Point.create(value: 1.0/0) - Point.last.value # => 0.0 - - After: - - Point.create(value: 1.0/0) - Point.last.value # => Infinity - - *Innokenty Mikhailov* - -* Allow the PostgreSQL adapter to handle bigserial primary key types again. - - Fixes #10410. - - *Patrick Robertson* - -* Deprecate joining, eager loading and preloading of instance dependent - associations without replacement. These operations happen before instances - are created. The current behavior is unexpected and can result in broken - behavior. - - Fixes #15024. - - *Yves Senn* - -* Fixed has_and_belongs_to_many's CollectionAssociation size calculation. - - has_and_belongs_to_many should fall back to using the normal CollectionAssociation's - size calculation if the collection is not cached or loaded. - - Fixes #14913, #14914. - - *Fred Wu* - -* Return a non zero status when running `rake db:migrate:status` and migration table does - not exist. - - *Paul B.* - -* Add support for module-level `table_name_suffix` in models. - - This makes `table_name_suffix` work the same way as `table_name_prefix` when - using namespaced models. - - *Jenner LaFave* - -* Revert the behaviour of `ActiveRecord::Relation#join` changed through 4.0 => 4.1 to 4.0. - - In 4.1.0 `Relation#join` is delegated to `Arel#SelectManager`. - In 4.0 series it is delegated to `Array#join`. - - *Bogdan Gusiev* - -* Log nil binary column values correctly. - - When an object with a binary column is updated with a nil value - in that column, the SQL logger would throw an exception when trying - to log that nil value. This only occurs when updating a record - that already has a non-nil value in that column since an initial nil - value isn't included in the SQL anyway (at least, when dirty checking - is enabled.) The column's new value will now be logged as `<NULL binary data>` - to parallel the existing `<N bytes of binary data>` for non-nil values. - - *James Coleman* - -* Rails will now pass a custom validation context through to autosave associations - in order to validate child associations with the same context. - - Fixes #13854. - - *Eric Chahin*, *Aaron Nelson*, *Kevin Casey* - -* Stringify all variables keys of MySQL connection configuration. - - When `sql_mode` variable for MySQL adapters set in configuration as `String` - was ignored and overwritten by strict mode option. - - Fixes #14895. - - *Paul Nikitochkin* - -* Ensure SQLite3 statements are closed on errors. - - Fixes #13631. - - *Timur Alperovich* - -* Give ActiveRecord::PredicateBuilder private methods the privacy they deserve. - - *Hector Satre* - -* When using a custom `join_table` name on a `habtm`, rails was not saving it - on Reflections. This causes a problem when rails loads fixtures, because it - uses the reflections to set database with fixtures. - - Fixes #14845. - - *Kassio Borges* - -* Reset the cache when modifying a Relation with cached Arel. - Additionally display a warning message to make the user aware. - - *Yves Senn* - -* PostgreSQL should internally use `:datetime` consistently for TimeStamp. Assures - different spellings of timestamps are treated the same. +* Add bigint primary key support for MySQL. Example: - mytimestamp.simplified_type('timestamp without time zone') - # => :datetime - mytimestamp.simplified_type('timestamp(6) without time zone') - # => also :datetime (previously would be :timestamp) - - See #14513. - - *Jefferson Lai* - -* `ActiveRecord::Base.no_touching` no longer triggers callbacks or start empty transactions. - - Fixes #14841. - - *Lucas Mazza* - -* Fix name collision with `Array#select!` with `Relation#select!`. - - Fixes #14752. - - *Earl St Sauver* - -* Fixed unexpected behavior for `has_many :through` associations going through a scoped `has_many`. - - If a `has_many` association is adjusted using a scope, and another `has_many :through` - uses this association, then the scope adjustment is unexpectedly neglected. - - Fixes #14537. - - *Jan Habermann* - -* `@destroyed` should always be set to `false` when an object is duped. - - *Kuldeep Aggarwal* - -* Fixed has_many association to make it support irregular inflections. - - Fixes #8928. - - *arthurnn*, *Javier Goizueta* - -* Fixed a problem where count used with a grouping was not returning a Hash. - - Fixes #14721. - - *Eric Chahin* - -* `sanitize_sql_like` helper method to escape a string for safe use in a SQL - LIKE statement. - - Example: - - class Article - def self.search(term) - where("title LIKE ?", sanitize_sql_like(term)) - end + create_table :foos, id: :bigint do |t| end - Article.search("20% _reduction_") - # => Query looks like "... title LIKE '20\% \_reduction\_' ..." - - *Rob Gilson*, *Yves Senn* - -* Do not quote uuid default value on `change_column`. - - Fixes #14604. - - *Eric Chahin* - -* The comparison between `Relation` and `CollectionProxy` should be consistent. - - Example: - - author.posts == Post.where(author_id: author.id) - # => true - Post.where(author_id: author.id) == author.posts - # => true - - Fixes #13506. - - *Lauro Caetano* - -* Calling `delete_all` on an unloaded `CollectionProxy` no longer - generates a SQL statement containing each id of the collection: - - Before: - - DELETE FROM `model` WHERE `model`.`parent_id` = 1 - AND `model`.`id` IN (1, 2, 3...) - - After: - - DELETE FROM `model` WHERE `model`.`parent_id` = 1 - - *Eileen M. Uchitelle*, *Aaron Patterson* - -* Fixed error for aggregate methods (`empty?`, `any?`, `count`) with `select` - which created invalid SQL. - - Fixes #13648. - - *Simon Woker* - -* PostgreSQL adapter only warns once for every missing OID per connection. - - Fixes #14275. - - *Matthew Draper*, *Yves Senn* - -* PostgreSQL adapter automatically reloads it's type map when encountering - unknown OIDs. - - Fixes #14678. - - *Matthew Draper*, *Yves Senn* - -* Fix insertion of records via `has_many :through` association with scope. - - Fixes #3548. - - *Ivan Antropov* - -* Auto-generate stable fixture UUIDs on PostgreSQL. - - Fixes #11524. - - *Roderick van Domburg* - -* Fixed a problem where an enum would overwrite values of another enum - with the same name in an unrelated class. - - Fixes #14607. - - *Evan Whalen* - -* PostgreSQL and SQLite string columns no longer have a default limit of 255. - - Fixes #13435, #9153. - - *Vladimir Sazhin*, *Toms Mikoss*, *Yves Senn* - -* Make possible to have an association called `records`. - - Fixes #11645. - - *prathamesh-sonpatki* - -* `to_sql` on an association now matches the query that is actually executed, where it - could previously have incorrectly accrued additional conditions (e.g. as a result of - a previous query). CollectionProxy now always defers to the association scope's - `arel` method so the (incorrect) inherited one should be entirely concealed. - - Fixes #14003. - - *Jefferson Lai* - -* Block a few default Class methods as scope name. - - For instance, this will raise: - - scope :public, -> { where(status: 1) } - - *arthurnn* - -* Fixed error when using `with_options` with lambda. - - Fixes #9805. - - *Lauro Caetano* - -* Switch `sqlite3:///` URLs (which were temporarily - deprecated in 4.1) from relative to absolute. - - If you still want the previous interpretation, you should replace - `sqlite3:///my/path` with `sqlite3:my/path`. - - *Matthew Draper* + *Ryuta Kamizono* -* Treat blank UUID values as `nil`. +* Support for any type primary key. - Example: + Fixes #14194. - Sample.new(uuid_field: '') #=> <Sample id: nil, uuid_field: nil> + *Ryuta Kamizono* - *Dmitry Lavrov* +* Dump the default `nil` for PostgreSQL UUID primary key. -* Enable support for materialized views on PostgreSQL >= 9.3. + *Ryuta Kamizono* - *Dave Lee* +* Add a `:foreign_key` option to `references` and associated migration + methods. The model and migration generators now use this option, rather than + the `add_foreign_key` form. -* The PostgreSQL adapter supports custom domains. Fixes #14305. + *Sean Griffin* - *Yves Senn* +* Don't raise when writing an attribute with an out-of-range datetime passed + by the user. -* PostgreSQL `Column#type` is now determined through the corresponding OID. - The column types stay the same except for enum columns. They no longer have - `nil` as type but `enum`. + *Grey Baker* - See #7814. +* Replace deprecated `ActiveRecord::Tasks::DatabaseTasks#load_schema` with + `ActiveRecord::Tasks::DatabaseTasks#load_schema_for`. *Yves Senn* -* Fixed error when specifying a non-empty default value on a PostgreSQL array column. - - Fixes #10613. - - *Luke Steensen* - -* Fixed error where .persisted? throws SystemStackError for an unsaved model with a - custom primary key that didn't save due to validation error. +* Fixes bug with 'ActiveRecord::Type::Numeric' that causes negative values to + be marked as having changed when set to the same negative value. - Fixes #14393. + Closes #18161. - *Chris Finne* + *Daniel Fox* -* Introduce `validate` as an alias for `valid?`. - - This is more intuitive when you want to run validations but don't care about the return value. - - *Henrik Nyh* - -* Create indexes inline in CREATE TABLE for MySQL. - - This is important, because adding an index on a temporary table after it has been created - would commit the transaction. - - It also allows creating and dropping indexed tables with fewer queries and fewer permissions - required. - - Example: - - create_table :temp, temporary: true, as: "SELECT id, name, zip FROM a_really_complicated_query" do |t| - t.index :zip - end - # => CREATE TEMPORARY TABLE temp (INDEX (zip)) AS SELECT id, name, zip FROM a_really_complicated_query +* Introduce `force: :cascade` option for `create_table`. Using this option + will recreate tables even if they have dependent objects (like foreign keys). + `db/schema.rb` now uses `force: :cascade`. This makes it possible to + reload the schema when foreign keys are in place. - *Cody Cutrer*, *Steve Rice*, *Rafael Mendonça Franca* - -* Use singular table name in generated migrations when - `ActiveRecord::Base.pluralize_table_names` is `false`. - - Fixes #13426. - - *Kuldeep Aggarwal* - -* `touch` accepts many attributes to be touched at once. - - Example: - - # touches :signed_at, :sealed_at, and :updated_at/on attributes. - Photo.last.touch(:signed_at, :sealed_at) - - *James Pinto* - -* `rake db:structure:dump` only dumps schema information if the schema - migration table exists. - - Fixes #14217. - - *Yves Senn* - -* Reap connections that were checked out by now-dead threads, instead - of waiting until they disconnect by themselves. Before this change, - a suitably constructed series of short-lived threads could starve - the connection pool, without ever having more than a couple alive at - the same time. - - *Matthew Draper* - -* `pk_and_sequence_for` now ensures that only the pg_depend entries - pointing to pg_class, and thus only sequence objects, are considered. - - *Josh Williams* + *Matthew Draper*, *Yves Senn* -* `where.not` adds `references` for `includes` like normal `where` calls do. +* `db:schema:load` and `db:structure:load` no longer purge the database + before loading the schema. This is left for the user to do. + `db:test:prepare` will still purge the database. - Fixes #14406. + Closes #17945. *Yves Senn* -* Extend fixture `$LABEL` replacement to allow string interpolation. - - Example: - - martin: - email: $LABEL@email.com - - users(:martin).email # => martin@email.com - - *Eric Steele* - -* Add support for `Relation` be passed as parameter on `QueryCache#select_all`. - - Fixes #14361. - - *arthurnn* - -* Passing an Active Record object to `find` or `exists?` is now deprecated. - Call `.id` on the object first. - - *Aaron Patterson* - -* Only use BINARY for MySQL case sensitive uniqueness check when column has a case insensitive collation. +* Fix undesirable RangeError by `Type::Integer`. Add `Type::UnsignedInteger`. *Ryuta Kamizono* -* Support for MySQL 5.6 fractional seconds. - - *arthurnn*, *Tatsuhiko Miyagawa* - -* Support for Postgres `citext` data type enabling case-insensitive where - values without needing to wrap in UPPER/LOWER sql functions. - - *Troy Kruthoff*, *Lachlan Sylvester* - -* Only save has_one associations if record has changes. - Previously after save related callbacks, such as `#after_commit`, were triggered when the has_one - object did not get saved to the db. - - *Alan Kennedy* - -* Allow strings to specify the `#order` value. - - Example: - - Model.order(id: 'asc').to_sql == Model.order(id: :asc).to_sql - - *Marcelo Casiraghi*, *Robin Dupret* - -* Dynamically register PostgreSQL enum OIDs. This prevents "unknown OID" - warnings on enum columns. - - *Dieter Komendera* - -* `includes` is able to detect the right preloading strategy when string - joins are involved. - - Fixes #14109. - - *Aaron Patterson*, *Yves Senn* - -* Fixed error with validation with enum fields for records where the - value for any enum attribute is always evaluated as 0 during - uniqueness validation. +* Add `foreign_type` option to `has_one` and `has_many` association macros. - Fixes #14172. + This option enables to define the column name of associated object's type for polymorphic associations. - *Vilius Luneckas* *Ahmed AbouElhamayed* + *Ulisses Almeida, Kassio Borges* -* `before_add` callbacks are fired before the record is saved on - `has_and_belongs_to_many` assocations *and* on `has_many :through` - associations. Before this change, `before_add` callbacks would be fired - before the record was saved on `has_and_belongs_to_many` associations, but - *not* on `has_many :through` associations. +* Remove deprecated behavior allowing nested arrays to be passed as query + values. - Fixes #14144. + *Melanie Gilman* -* Fixed STI classes not defining an attribute method if there is a - conflicting private method defined on its ancestors. +* Deprecate passing a class as a value in a query. Users should pass strings + instead. - Fixes #11569. + *Melanie Gilman* - *Godfrey Chan* +* `add_timestamps` and `remove_timestamps` now properly reversible with + options. -* Coerce strings when reading attributes. Fixes #10485. - - Example: - - book = Book.new(title: 12345) - book.save! - book.title # => "12345" - - *Yves Senn* - -* Deprecate half-baked support for PostgreSQL range values with excluding beginnings. - We currently map PostgreSQL ranges to Ruby ranges. This conversion is not fully - possible because the Ruby range does not support excluded beginnings. - - The current solution of incrementing the beginning is not correct and is now - deprecated. For subtypes where we don't know how to increment (e.g. `#succ` - is not defined) it will raise an ArgumentException for ranges with excluding - beginnings. - - *Yves Senn* + *Noam Gagliardi-Rabinovich* -* Support for user created range types in PostgreSQL. +* `ActiveRecord::ConnectionAdapters::ColumnDumper#column_spec` and + `ActiveRecord::ConnectionAdapters::ColumnDumper#prepare_column_options` no + longer have a `types` argument. They should access + `connection#native_database_types` directly. *Yves Senn* -Please check [4-1-stable](https://github.com/rails/rails/blob/4-1-stable/activerecord/CHANGELOG.md) for previous changes. +Please check [4-2-stable](https://github.com/rails/rails/blob/4-2-stable/activerecord/CHANGELOG.md) for previous changes. |
