bump...
My current working theory is that for some (to me) unknown reason
(performance?) habtm relationships are created and deleted without
fully utilizing the joining model. That is when you do:
$data = array(
'A' => stuff for A,
'B' =>array('B'=>array(1,3,4))
);
$this->A->save($data);
So I am thinking that I have to change the way I save these.
Possibly I need to g as far as using $this->AB->delete() directly for
unlinking.
And, or-course, anyone who has been down this road before could be of
great help by nudging me in the right direction.
Non-essential background information:
The reason I want to use the save and delete callbacks is that I want
to put together a custom "counterCache" for a habtm relationship. That
is why I want to trigger an update each time a "link" is created or
deleted.
