How to use KNPPaginatorBundle to paginate results using Doctrine Repository?

Question

I\'m working on a Symfony2 project and I decided to use KNPPaginatorBundle to build an easy pagination system. So I created a Product entity and I want to add the paginator to i

In our project we want to avoid using Doctrine queries in controllers. We have also separate layers. Controllers must not access the database. So I included pagination in the Repository.

Here my code in controller:

public function indexAction(Request $request)
{
    $userRepository = $this->get('user_repository');
    $page = intval($request->query->get('page', 1));
    $pages = 0;
    $users = $userRepository->findAllPaginated($pages, $page - 1, 10);

    return $this->render('User:index.html.twig', array(
        'users' => $users,
        'page' => $page,
        'pages' => $pages,
    ));
}

And here is the important code in my repository:

use Doctrine\ORM\Tools\Pagination\Paginator;
class UserRepository extends EntityRepository
{
    /**
     * @return User[]
     */
    public function findAllPaginated(&$pages, $startPage = 0, $resultsPerPage = 5)
    {
        $dql = 'SELECT u FROM CoreBundle:User u';
        $query = $this->getEntityManager()->createQuery($dql)
            ->setFirstResult($startPage * $resultsPerPage)
            ->setMaxResults($resultsPerPage);

        $paginator = new Paginator($query);
        $count = $paginator->count();
        $pages = floor($count/$resultsPerPage);

        return $paginator; // on $paginator you can use "foreach", so we can say return value is an array of User
    }
}
