I think the best thing you could do, as a new Cake user, is to pretend
you never saw this method. It's is a little-known shortcut that
requires a pretty good understanding of how Cake operates.
That said, what the method does is apply the values from the 2nd param
array to the find conditions so as to change the query. The above
example would be equivalent to:
$this->Order->find(
'all',
array(
'conditions' => array(
'num_items >=' => '4',
'referrer LIKE' => 'Ye Olde'
)
)
)
And compact() is another convenience:
