Get entityManager inside an Entity

Question

I\'d like to use, something like:

$em = $this->getEntityManager();

Inside a Entity.

I understand I should do this as a s

What I think you should do is, instead of using the Entity Manager inside your entity, is to create a custom repository for your entity.

In your entity ORM file, add an entry as follows (or in your entity class annotations if not using YML):

App\Bundle\Profils: 
# Replace the above as appropiate
    type: entity
    table: (your table)
    ....
    repositoryClass: App\Bundle\CustomRepos\ProfilsRepository
    # Replace the above as appropiate. 
    # I always put my custom repos in a common folder, 
    # such as CustomRepos

Now, create a new PHP class that has the namespace above:

//Your ProfilsRepository.php
getEntityManager();
       $qb = $em->createQueryBuilder();
       $qb->select... (your logic to retrieve the profil object);

       $query = $qb->getQuery();
       $result = $query->getResult();

       return $result;
    }
}

Finally, in your Controller:

// Your controller
;
   ...
   use App\Bundle\CustomRepos\ProfilsRepository;
   use Symfony\Bundle\FrameworkBundle\Controller\Controller;
   ...
   class YourClassNameController extends Controller
   {
      public function yourAction()
      {
         $userId = ;
         // Pass the name of your entity manager to the 
         // getManager function if you have more than one and
         // didn't define any default
         $em = $this->getDoctrine()->getManager();
         $repo = $em->getRepository('Profils');
         $avatar = $repo->getUserProfile($userId);
         ...

      }
   }
