I never do that directly.
What I do is that I update either of the models involved with the
association either added or removed.
This si an example straight out of a project I am working on. It is
for Cake1.2. A quick disclaimer though: It may not at all be the best
way and it may not at all be obvious what it does since it is all
ongoing pre-release stressed-out code. It also helps to have read up
on how HABTMs are saved.
I have two models involved. User and Module. They are HABTM
associated, creating kind of like a simple high-level permission. The
following code is found in the User model and is used to toggle the
association on and off between a user and a module. ($user is passed
as a User-array since the controller or other part of the model may
want to update other fields before calling this method)
---start---
function toggleModule($user, $module_id)
{
$new_mod = $this->Module->findById($module_id);
if ( $new_mod )
{
$existing_ids = Set::extract($user['Module'], '{n}.id');
if ( in_array($new_mod['Module']['id'], $existing_ids) )
{
foreach ( $existing_ids as $i => $id )
{
if ( $id == $new_mod['Module']['id'] )
{
unset($existing_ids[$i]);
}
}
}else{
$existing_ids[] = $new_mod['Module']['id'];
}
unset($user['Module']);
sort($existing_ids);
$user['Module']['Module'] = $existing_ids;
$this->save($user);
return true;
}else{
return false;
}
}
---end---
Just ask if something if unclear and I'll try to answer as best I can
