I'm not sure that I follow all that but here's what I use:
function parentNode()
{
if (!$this->id) return null;
$data = $this->read();
return $data['User']['group_id']
? array (
'model' => 'Group',
'foreign_key' => $data['User']['group_id']
)
: null;
}
That looks like it would work for you but there area variety of ways
of doing this. It really depends on the model. In the same app I have
a Section model that has:
public function parentNode()
{
if (!$this->id) return null;
$parent_id = $this->field(
'parent_id',
array('Section.id' => $this->id)
);
return $parent_id
? array(
'model' => 'Section',
'foreign_key' => $parent_id
)
: null;
}
