José Valim	2a25c5818b	Revert "Handle enabling/disabling observers at different levels of the class hierarchy." ... This reverts commit ad62f19287 because the current subclasses implementation leaks memory in development. Instead of keeping an array of subclasses, the better solution is to ask the parent if an observer is being disabled or not.	2011-04-28 09:32:57 +02:00
Myron Marston	ad62f19287	Handle enabling/disabling observers at different levels of the class hierarchy. ... Last call wins.	2011-04-28 10:25:07 +08:00
Myron Marston	1f8cc446d9	Allow observers to be enabled and disabled. ... This is useful in situations like model unit tests and the occasional rake task to backfill old data.	2011-04-28 10:23:49 +08:00
