* Avoid passing unnecessary arguments to relationDaniel Colson2018-01-241-0/+8
| | | | | | | | | | | | Most of the time the table and predicate_builder passed to Relation.new are exactly the arel_table and predicate builder of the given klass. This uses klass.arel_table and klass.predicate_builder as the defaults, so we don't have to pass them in most cases. This does change the signaure of both Relation and AssocationRelation. Are we ok with that?
* Don't update counter cache when through record was not destroyedEugene Kenny2018-01-142-0/+7
| | | | | | When removing a record from a has many through association, the counter cache was being updated even if the through record halted the callback chain and prevented itself from being destroyed.

| * When deleting through records, take into account association conditionsPiotr Jakubowski2016-05-041-0/+3
| | | | | | | | | | | | | | | | Fixes #18424. When deleting through records, it didn't take into account the conditions that may have been affecting join model table, but was defined in association definition.
* | Fix newly added reflection order when redefining associationRyuta Kamizono2018-01-041-2/+2
| | | | | | | | | | | | | | | | | | | | Currently reflections keeps the order when first added even if when redefining association. As a result of the order, redefining through association which use newly added association will raise `HasManyThroughOrderError`. We need to redefine reflection order as well when redefining association. Fixes #31068.
* | Merge pull request #27561 from fishbrain/count-all-in-has-many-associationRyuta Kamizono2018-01-031-0/+2
|\ \ | | | | | | | | | Use `count(:all)` in HasManyAssociation#count_records
| * | Use `count(:all)` in HasManyAssociation#count_recordsKlas Eskilson2017-02-071-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Calling `count` on an association can cause invalid SQL queries to be created where the `SELECT COUNT(a, b, c)` function receives multiple columns. This will cause a `StatementInvalid` exception later on. Solution: Use `count(:all)`, which generates a `SELECT COUNT(*)...` query independently of the association. This also includes a test case that, before the fix, broke.
* | | Add test case for `collection_singular_ids` with symbol primary keysRyuta Kamizono2018-01-011-1/+1

* | | save attributes changed by callbacks after update_attributeMike Busch2017-12-221-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | update_attribute previously stopped execution, before saving and before running callbacks, if the record's attributes hadn't changed. [The documentation](http://api.rubyonrails.org/classes/ActiveRecord/Persistence.html#method-i-update_attribute) says that "Callbacks are invoked", which was not happening if the persisted attributes hadn't changed.

| | | | | | | | | | | | | | | | | | | | | | | | A relation includes `klass`, so it can not be used as it is if current class is different from `current_scope.klass`. It should be created new relation by current class to respect the klass and STI constraint. Fixes #17603. Fixes #23576.

| | | | | | | | | | | | | | | | | | | | | | | | | | | The order of scope evaluation should be from through scope to the association's own scope. Otherwise the association's scope cannot affect to through scope. Fixes #13677. Closes #28449.

| | | | | | | | | | | | | | | | | | | | | | | | Defined scope treats nil as `all`, but scope in associations isn't so. If the result of the scope is nil, most features on associations will be broken. It should treat nil as `all` like defined scope. Fixes #20823.

| * | | Add test for fixed `counter_cache` double incrementLisa Ugray2017-07-191-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When an `after_create` callback did `update_attributes` on a record with multiple `belongs_to` associations with counter caches, even numbered associations would have their counters double-incremented. Fixes to `ActiveModel::Dirty` in 020abad fixed this. This adds regression tests for this bug fixed incidentally in the other commit, which also removed the need for the workaround using @_after_create_counter_called.
