Lin Jen-Shin	5747b0d3ed	Make deleting with optimistic locking respect NULL ... For now deleting with optimistic locking is broken when lock_version is still NULL, because Rails would try to delete with `lock_version = 0` while in the database the column is still `NULL`. The monkey patches would force Rails just pass whatever in the column, and stop Rails from casting `NULL` into `0` when the value is read from database. Closes #24766	2016-12-01 16:17:20 +08:00
