We are using foreign keys with "ON DELETE CASCADE" to delete child records when parents are deleted, instead of dependent: :destroy, for performance reasons. The docs say "This will only work on associations that are dependent destroy. It should be trival to change that or make it optional." Could you provide more details if there is a suggested workaround for archiving children when a parent is archived? Also, would it be possible to auto-archive children with a dependent: :delete_all relationship in addition to dependent: :destroy?
