* Do not invoke callbacks when delete_all is calledNeeraj Singh2013-06-303-0/+13
| | | | | | | | | | | Method `delete_all` should not be invoking callbacks and this feature was deprecated in Rails 4.0. This is being removed. `delete_all` will continue to honor the `:dependent` option. However if `:dependent` value is `:destroy` then the default deletion strategy for that collection will be applied. User can also force a deletion strategy by passing parameter to `delete_all`. For example you can do `@post.comments.delete_all(:nullify)`

* Fix the `:primary_key` option for `has_many` associations.Yves Senn2013-05-231-0/+1
| | | | | | | | | | | | | | | | | When removing records from a `has_many` association it used the `primary_key` defined on the association. Our test suite didn't fail because on all occurences of `:primary_key`, the specified column was available in both tables. This prevented the code from raising an exception but it still behaved badly. I added a test-case to prevent regressions that failed with: ``` 1) Error: HasManyAssociationsTest#test_has_many_assignment_with_custom_primary_key: ActiveRecord::StatementInvalid: SQLite3::SQLException: no such column: essays.first_name: UPDATE "essays" SET "writer_id" = NULL WHERE "essays"."writer_id" = ? AND "essays"."first_name" IS NULL ```

* Handle aliased attributes in ActiveRecord::Relation.Godfrey Chan2013-05-011-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | 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')`. Github #7839 *Godfrey Chan*
* Fix scope chaining + STIJon Leighton2013-04-051-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | See #9869 and #9929. The problem arises from the following example: class Project < ActiveRecord::Base scope :completed, -> { where completed: true } end class MajorProject < Project end When calling: MajorProject.where(tasks_count: 10).completed This expands to: MajorProject.where(tasks_count: 10).scoping { MajorProject.completed } However the lambda for the `completed` scope is defined on Project. This means that when it is called, `self` is Project rather than MajorProject. So it expands to: MajorProject.where(tasks_count: 10).scoping { Project.where(completed: true) } Since the scoping was applied on MajorProject, and not Project, this fails to apply the tasks_count condition. The solution is to make scoping apply across STI classes. I am slightly concerned about the possible side-effects of this, but no tests fail and it seems ok. I guess we'll see.

| | | | | | | | PR #5210 added a Friendship model to illustrate a bug, but in doing so created a confusing structure because both belongs_to declarations in Friendship referred to the same side of the join. The new structure maintains the integrity of the bug test while changing the follower relationship to be more useful for other testing.
* rename `Relation#uniq` to `Relation#distinct`. `#uniq` still works.Yves Senn2013-03-154-11/+10
| | | | | | | | The similarity of `Relation#uniq` to `Array#uniq` is confusing. Since our Relation API is close to SQL terms I renamed `#uniq` to `#distinct`. There is no deprecation. `#uniq` and `#uniq!` are aliases and will continue to work. I also updated the documentation to promote the use of `#distinct`.

* Prevent Relation#merge from collapsing wheres on the RHSJon Leighton2013-01-272-0/+2
| | | | | | | | | | | | | | | | | | | | | | | This caused a bug with the new associations implementation, because now association conditions are represented as Arel nodes internally right up to when the whole thing gets turned to SQL. In Rails 3.2, association conditions get turned to raw SQL early on, which prevents Relation#merge from interfering. The current implementation was buggy when a default_scope existed on the target model, since we would basically end up doing: default_scope.merge(association_scope) If default_scope contained a where(foo: 'a') and association_scope contained a where(foo: 'b').where(foo: 'c') then the merger would see that the same column is representated on both sides of the merge and collapse the wheres to all but the last: where(foo: 'c') Now, the RHS of the merge is left alone. Fixes #8990
* Fix cases where delete_records on a has_many association caused errorsDerek Kraan2013-01-272-0/+6
| | | | | | | | | | | | | because of an ambiguous column name. This happened if the association model had a default scope that referenced a third table, and the third table also referenced the original table (with an identical foreign_key). Mysql requires that ambiguous columns are deambiguated by using the full table.column syntax. Postgresql and Sqlite use a different syntax for updates altogether (and don't tolerate table.name syntax), so the fix requires always including the full table.column and discarding it later for Sqlite and Postgresql.

* Remove warning by using a custom coderAndrew White2013-01-231-2/+16
| | | | | | | | | | | | | | The native JSON library bypasses the `to_json` overrides in active_support/core_ext/object/to_json.rb by calling its native implementation directly. However `ActiveRecord::Store` uses a HWIA so `JSON.dump` will call our `to_json` instead with a `State` object for options rather than a `Hash`. This generates a warning when the `:encoding`, `:only` & `:except` keys are accessed in `Hash#as_json` because the `State` object delegates unknown keys to `instance_variable_get` in its `:[]` method. Workaround this warning in the test by using a custom coder that calls `ActiveSupport::JSON.encode` directly.
