Re: Undesired Recursion in Models

Well the recursion is just symbolic. Cake will only create one
instance for each of your models and uses references to that one model
throughout your app. You can test this out in your controller.

var $uses = array('Site', 'Post');

function test(){
if ($this->Site->Post === $this->Post) {
echo 'adam is right!';
} else {
echo 'ok adam lied!';
}
exit;
}

So really the only issue is that you're requesting more data from your
models than you actually want. This is where the Containable behavior
comes in. It will automatically prune your recursive associations
based on what data you want.

But you can read up on that elsewhere. Hope this helps and best of
luck with your project!

Cheers,
Adam
