Re: CakeDC Categories with Associated Models

That works super-great for something like view.ctp where you're dealing with a single entity/record. That's exactly what I've done for those situations. The issue becomes much, much more complicated for something like index.ctp where you have to apply it to every record with a foreach loop. It's much easier to do that in the view file than the cumbersome route of creating the array in the model, calling it into the controller and passing it on to the view. (I know it's Cake heresy to say that, but it is totally complicated the Cake way.) I suppose I'll have to do it that way.

I think you're mixing up Models and Helpers. Your Collection model has
an association with Categories.Category, using the alias Category, so
you can do $this->Collection->Category->whatever()

But, you can't call model methods in the view. You can, but you
shouldn't. From the view's perspective, $this->SomeClass is a call to
a helper. And to do that you need to include it in the controller's
$helpers array.

The simplest solution would be to just make the call to the model from
the controller action and set the returned string as a view var:

$this->set('path', $this->Collection->Category->catFullPath(...));

Better yet, create an afterFind() method in the model and add the full
path to your data array.
