Is there a way to put request variables in paginate class property?

I want to sort an array of data in my index action and one condition depends on the id given by the request object (attraction_id). Is there a way to set up the paginate component as a controller class method (see under)?

<?php

class AttractionCommentsController extends CoasterCmsAppController
{
    public $paginate = array(
        'AttractionComment' => array(
            'conditions' => array(
                'Attraction.id' => $this->request->params['named']['attraction_id'],
                'AttractionComment.deleted' => null
            ),
            'order' => array(
                'AttractionComment.created' => 'DESC',
                'AttractionComment.id' => 'ASC'
            ),
            'limit' => 15
        )
    );
   
    public function index()
    {
        $this->Paginator->settings = $this->paginate;
       
        $comments = $this->Paginator->paginate('AttractionComment');
       
        $this->set('comments', $comments);
    }

?>

The above code can't handle the request variable ($this->request->params['named']['attraction_id']) within the class method.

So... is there a solution for this or is it required to drop the class property and do something like this:

<?php

class AttractionCommentsController extends CoasterCmsAppController
{
    public function index()
    {

        $this->Paginator->settings = array(
            'AttractionComment' => array(
                'conditions' => array(
                    'Attraction.id' => $this->request->params['named']['attraction_id'],
                    'AttractionComment.deleted' => null
                ),
                'order' => array(
                    'AttractionComment.created' => 'DESC',
                    'AttractionComment.id' => 'ASC'
                ),
                'limit' => 15
            )
        );        
        $comments = $this->Paginator->paginate('AttractionComment');
       
        $this->set('comments', $comments);
    }

?>

Thx 4 helping!
