Symfony2: How to access to service from repository

Question

I have class ModelsRepository:

class ModelsRepository extends EntityRepository
{}

And service

container_data:
 class:        ProjectName\MyBundle\Common\Container
 arguments:    [@service_container]

I want get access from ModelsRepository to service container_data. I can't transmit service from controller used constructor.

Do you know how to do it?

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'

Answer 2

I tried some versions. Problem was solved follows

ModelRepository:

class ModelRepository extends EntityRepository
{
    private $container;

    function __construct($container, $em) {
        $class = new ClassMetadata('ProjectName\MyBundle\Entity\ModelEntity');
        $this->container = $container;

        parent::__construct($em, $class);
    }
}

security.yml:

providers:
    default:
        id: model_auth

services.yml

model_auth:
    class: ProjectName\MyBundle\Repository\ModelRepository
    argument

As a result I got repository with ability use container - as required. But this realization can be used only in critical cases, because she has limitations for Repository. Thx 4all.
