This feature has been supported since 9.1. + + *kennyj* + +* Deprecate `ConnectionAdapters::SchemaStatements#distinct`, + as it is no longer used by internals. + + *Ben Woosley# + +* Fix pending migrations error when loading schema and `ActiveRecord::Base.table_name_prefix` + is not blank. + + Call `assume_migrated_upto_version` on connection to prevent it from first + being picked up in `method_missing`. + + 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`. + + Fixes #10411. + + *Kyle Stevens* + +* Method `read_attribute_before_type_cast` should accept input as symbol. + + *Neeraj Singh* + +* Confirm a record has not already been destroyed before decrementing counter cache. + + *Ben Tucker* + +* 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`. + + *Zach Ohlgren* + +* While removing index if column option is missing then raise IrreversibleMigration exception. + + Following code should raise `IrreversibleMigration`. But the code was + failing since options is an array and not a hash. + + def change + change_table :users do |t| + t.remove_index [:name, :email] + end + end + + Fix was to check if the options is a Hash before operating on it. + + Fixes #10419. + + *Neeraj Singh* + +* Do not overwrite manually built records during one-to-one nested attribute assignment + + 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.: + + class Member < ActiveRecord::Base + has_one :avatar + accepts_nested_attributes_for :avatar + + def avatar + super || build_avatar(width: 200) + end + end + + member = Member.new + member.avatar_attributes = {icon: 'sad'} + member.avatar.width # => 200 + + *Olek Janiszewski* + +* 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. + + *Johnny Holton* + +* Handle aliased attributes in ActiveRecord::Relation. + + When using symbol keys, ActiveRecord will now translate aliased attribute names to the actual column name used in the database: + + With the model + + class Topic + alias_attribute :heading, :title + end + + The call + + Topic.where(heading: 'The First Topic') + + should yield the same result as + + Topic.where(title: 'The First Topic') + + This also applies to ActiveRecord::Relation::Calculations calls such as `Model.sum(:aliased)` and `Model.pluck(:aliased)`. + + This will not work with SQL fragment strings like `Model.sum('DISTINCT aliased')`. + + *Godfrey Chan* + +* Mute `psql` output when running rake db:schema:load. + + *Godfrey Chan* + +* Trigger a save on `has_one association=(associate)` when the associate contents have changed. + + Fix #8856. + + *Chris Thompson* + +* Abort a rake task when missing db/structure.sql like `db:schema:load` task. + + *kennyj* + +* rake:db:test:prepare falls back to original environment after execution. + + *Slava Markevich* Please check [4-0-stable](https://github.com/rails/rails/blob/4-0-stable/activerecord/CHANGELOG.md) for previous changes. |
