There's no 'order' key in your $paginate array. Declare $paginate as a
class variable (up at the top, outside of your methods). Maybe you did
do that but, in your example, you've re-declared the variable, rather
than make adjustments to it.
var $paginate = array(
'Membership' => array(
'fields' => ...
'order' => ...
'limit' => ...
)
);
function my_index()
{
// you can use AuthComponent to get User id
$this->paginate['Membership']['conditions'] = array(
'Membership.user_id' => $this->Auth->user('id')
);
$this->paginate['Membership']['limit'] = 25;
$this->set('groups', $this->paginate('Membership'));
}
However, you should first ensure that your class-wide $paginate works
correctly before adding the other conditions.
Also, I wonder why you're using pagination here at all. If the results
you're looking for are all the Groups for a particular User do you
really need to paginate them? Are there going to be that many?
