In Rails 2.x, calling touch on an ActiveRecord model would update the 'lock_version' on the model, if it were present.
It would produce something like this in SQL: UPDATE `foo` SET `updated_at` = '2010-07-23 10:44:19', `lock_version' = 2 WHERE 'lock_version' = 1 This would ensure that your optimistic locking policy will be followed should another concurrent update occur on that row in your database. Rails 3 no longer updates the 'lock_version' column through the touch method. I preferred the Rails 2 behaviour, I was wondering if anyone knew the reasoning behind this change?
