Re: how to adress specific data from related models?

Turn on debugging (Configure::write('debug', 2); within /app/config/core.php) and type debug($this->data); (and perhaps die; as well) at the top of your controller function and you'll see exactly what's been posted. Then it's a case of accessing the right part of the array to get the values you want.
