使用自定义存储库填充表单中的实体字段，而不是使用查询构建器

Question

I have a form that consist of an entity field like bellow

$builder->add('rating', 'entity', array(
         'class' => 'MyBundle:Rating',
         'query_builder' => function(EntityRepository $er) {
                return $er->createQueryBuilder('u')
                    ->orderBy('u.id', 'ASC');
            },      

In this form I can use a query builder to have a custom selection of Rating entity. But since I have a custom repository for Rating entity like bellow, I want to use the loadAllRoots() method in the RatingRepository class for filling the rating entity in my form instead of using query builder.

class RatingRepository extends EntityRepository 
{

    public function loadAllRoots()
    {
        return $this->getEntityManager()
            ->createQuery('SELECT r FROM MyBundle:Rating r WHERE  r.parent IS NULL')
        ->getResult();
    }

Best

Ok, a solution would be defining my forms as a service and then injecting the entity manager. Then I can use my repositories.
