* | | Improve DELETE with JOIN handling to avoid subqueries if possibleRyuta Kamizono2018-10-102-9/+8

* | | Fix `AssociationRelation` not to set inverse instance key just like beforeRyuta Kamizono2018-10-072-3/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since #31575, `set_inverse_instance` replaces the foreign key by the current owner immediately to make it happen when a record is added to collection association. But `set_inverse_instance` is not only called when a record is added, but also when a record is loaded from queries. And also, that loaded records are not always associated records for some reason (using `or`, `unscope`, `rewhere`, etc). It is hard to distinguish whether or not we should invoke `set_inverse_instance`, but at least we should avoid the undesired side-effect which was brought from #31575. Fixes #34108.

With this feature we don't need to write an extra line to add index for column. We can just use `index` option. Old behaviour in action: ``` change_table(:languages) do |t| t.string :country_code t.index: :country_code end ``` New behaviour in action: ``` change_table(:languages) do |t| t.string :country_code, index: true end ``` Exactly same behaviour is already exist for `create_table` migrations.
