The paginator is just a shortcut to getting the count and limiting your
results, so you can essentially pass any conditions you would in a normal
find. This means for joins, like belongsTo, you can.
For example with Profile belongsTo User you could sort by Profile and User
fields, assuming your pass recursive to your pagination options to include
the models.
Additionally, for complex pagination, you can add a "paginate" method to
your model and paginate using that method instead. Your controller code
would look like:
// note we're passing the model object here
$this->Paginator->paginate($this->MyModel);
Then on your model
class MyModel extends AppModel {
function paginate($conditions, $fields, $order, $limit, $page,
$recursive, $extra) {
//special pagination
}
}
