Symfony2: How to access to service from repository

Question

I have class ModelsRepository:

class ModelsRepository extends EntityRepository
{}

And service

container_data:
 class:               


        

Answer 1

I strongly agree that this should only be done when absolutely necessary. Though there is a quite simpler approach possible now (tested with Symfony 2.8).

1. Implement in your repository "ContainerAwareInterface"
2. Use the "ContainerAwareTrait"
3. adjust the services.yml

RepositoryClass:

namespace AcmeBundle\Repository;

use Doctrine\ORM\EntityRepository;
use Symfony\Component\DependencyInjection\ContainerAwareInterface;
use Symfony\Component\DependencyInjection\ContainerAwareTrait;
use AcmeBundle\Entity\User;

class UserRepository extends EntityRepository implements ContainerAwareInterface
{

    use ContainerAwareTrait;

    public function findUserBySomething($param)
    {
        $service = $this->container->get('my.other.service');
    }

}

services.yml:

acme_bundle.repository.user:
    lazy: true
    class: AcmeBundle\Repository\UserRepository
    factory: ['@doctrine.orm.entity_manager', getRepository]
    arguments:
        - "AcmeBundle:Entity/User"
    calls:
        - method: setContainer
          arguments:
            - '@service_container'

Are you sure that is a good idea to access service from repo?

Repositories are designed for custom SQL where, in case of doctrine, doctrine can help you with find(),findOne(),findBy(), [...] "magic" methods.

Take into account to inject your service where you use your repo and, if you need some parameters, pass it directly to repo's method.
