I was stumbling because I thought the beforeSave() was an all or
nothing thing. So if you return true, the save function....the ENTIRE
save function executes. So I was trying to query bits of the save
function to specifically stop the insert query on the HABTM table.
Now I realize that if I unset the key variable of the HABTM
relationship, cake knows to not make the insert. So here's the
solution in the User model to the above problem:
function beforeSave() {
if ($this->data['User']['role_id'] != 'Club Administrator') {
unset($this->data['Club']['Club']);
}
}
FOLLOW-UP QUESTION:
Is there a way to detect the action the controller is executing so I
can wrap the if..then in a condition like:
if ($this->action) {
}
...that of course does not work...but what would get me the current
users_controller action?
Thanks!
