Callback has_many

Hi everyone,

I am implementing fragment caching in my application

I’ve got the following architecture :

A :has_many Cs :through Bs

I’ve got a sweeper that observes B, in which I’ve got 2 methods :
after_create(B) and after_delete(B), which expire a fragment of my
cache.

In my main controller, I adding/removing Cs to As like this :

A << C, and this actually calls back after_create(B), as expected

and

A.Cs.delete© which doesn’t perform any call to after_delete(B), even
though, the B element is actually deleted!

Is this a normal behavior? If so, why is the call back only called when
creating and not deleting? And is there a “smart” way to actually call
by sweeper on delete?

Thanks for your help!
