Re: Proper MVC location for a function and its call

With the method in the model, be sure to change this line:

$this->TopicTree->getPath(...)

to:

$this->getPath(...)


If you want the value in the view, you should use set() in the controller:

$this->set(
'level',
$this->TopicTree->getLevel($id)
);

This creates a variable that View can access as $level.

Tip: if you have debug set to 1 or 2 (avoid 3 as it creates far too
much info and is best left for serious debugging problems) you can do
this in a model, controller, or view:

die(debug($some_var));
