How to get a Respository from an Entity?

Question

I have an Entity called Game with a related Repository called GameRepository:

/**
 * @ORM\\Entity(repositoryClass=\"...\\GameReposi

You actually can get the repository in your entity and only during a lifecycle callback. You are very close to it, all you have to do is to receive the LifecycleEventArgs parameter.

Also see http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/reference/events.html

use Doctrine\ORM\Event\LifecycleEventArgs;

/**
 * @ORM\Entity(repositoryClass="...\GameRepository")
 * @ORM\HasLifecycleCallbacks()
 */
class Game {
    /**
     * @ORM\prePersist
     */
    public function setSlugValue( LifecycleEventArgs $event ) {
        $entityManager = $event->getEntityManager();
        $repository    = $entityManager->getRepository( get_class($this) );

        $this->slug = $repository->createUniqueSlugForGame();
    }
}

PS. I know this is an old question, but I answered it to help any future googlers.
