Question

I setup a listener class where i’ll set the ownerid column on any doctrine prePersist. My services.yml file looks like this …

services:
my.listener:
    class: App\SharedBundle\Listener\EntityListener
    arguments: ["@security.context"]
    tags:
        - { name: doctrine.event_listener, event: prePersist }

and my class looks like this …

use Doctrine\ORM\Event\LifecycleEventArgs;
use Symfony\Component\Security\Core\SecurityContextInterface;

class EntityListener
{

protected $securityContext;

public function __construct(SecurityContextInterface $securityContext)
{
    $this->securityContext = $securityContext;
}


/**
 *
 * @param LifecycleEventArgs $args 
 */
public function prePersist(LifecycleEventArgs $args)
{

    $entity = $args->getEntity();
    $entityManager = $args->getEntityManager();

    $entity->setCreatedby();

}
}

The result of this is the following error.

ServiceCircularReferenceException: Circular reference detected for service “doctrine.orm.default_entity_manager”, path: “doctrine.orm.default_entity_manager -> doctrine.dbal.default_connection -> my.listener -> security.context -> security.authentication.manager -> fos_user.user_manager”.

My assumption is that the security context has already been injected somewhere in the chain but I don’t know how to access it. Any ideas?

I had similar problems and the only workaround was to pass the whole container in the constructor (arguments: ['@service_container']).

use Doctrine\ORM\Event\LifecycleEventArgs;
use Symfony\Component\DependencyInjection\ContainerInterface;

class MyListener
{
    protected $container;

    public function __construct(ContainerInterface $container)
    {
        $this->container = $container;
    }

    // ...

    public function prePersist(LifeCycleEventArgs $args)
    {
        $securityContext = $this->container->get('security.context');

        // ...
    }
}
