I was overthinking the bind. Instead of bindModel() in the controller, just
needed the following association in the Page model:
var $hasOne = array(
'PageViewTotal' => array(
'className' => 'PageView',
'type' => 'inner'
)
);
Between that and the afterFind() callback, seems to do the trick and be a
fairly pure solution. Still seems like if the models were set up correctly,
I could get page_view_count in the Page dimension of the array without
having to manipulate it there using afterFind().
As I am trying to learn, any comments as to the effectiveness of this
solution and/or ways to improve would be much appreciated.
