Question

We can easily custom the powerful Symfony2 form component with an entity Field Type

use Doctrine\ORM\EntityRepository;
// ...

$builder->add('users', 'entity', array(
    'class' => 'AcmeHelloBundle:User',
    'query_builder' => function(EntityRepository $er) {
        return $er->createQueryBuilder('u')
            ->orderBy('u.username', 'ASC');
    },
));

Is there a way to inject a method using a custom Entitymanager (UserManager in this case) instead? I am thinking that in the case of long queries, it might be interesting to have the option to use custom methods from an EntityManager instead?

Answer 1

Each form can be described as a service in service container so you can specify any dependencies from any other services. I would say it’s a good idea to encapsulate queries inside repository/usermanager instead of using them inline. Ihmo symfony version does not matter in this case.
