Just recently ( end of May, 2008 ) there was an addition to CakePHP’s find method to easily build a GROUP BY in your SQL.

If you’ve been using something like $this->Product->find(‘all’… etc., etc. Now you can add a new key ‘group’ to your find method, like so:

$this->Product->find(‘all’,array(‘fields’=>array(‘Product.type’,’MIN(Product.price) as price’), ‘group’=> ‘Product.type’));

Of course you will have to upgrade to a nightly SVN core for this to work.
