[FIXED] Symfony grabbing data from proxy object

Issue

I have the following code to grab an array with 1 App\Entity\Player inside of it. I want to get the name property of the club. Which gives me an error: App\Entity\Player::getClub(): Return value must be of type Club, Proxies_CG_\App\Entity\Club returned. How am I able to grab the club name for instance?

        $player_data = array();

        $em = $this->getDoctrine()->getManager();
        $query = $em->createQuery("SELECT p FROM App\Entity\Player p  WHERE p.user = :id");
        $query->setParameter('id', $user_id);
        $player = $query->getResult();
        array_push($player_data, $player[0]->getClub()->getName());

When I dump the $player object I get the following: Note the Proxies_CG_\App\Entity\Club

HomeController.php on line 37:
array:1 [▼
  0 => App\Entity\Player {#727 ▼
    -id: 7

Solution

Doctrine Proxy automatically extends your entity (App\Entity\Club). But in the return type of your method getClub() on Player entity you have \Club (without namespace at all). It is not the same as App\Entity\Club (namespace App\Entity). You need to change this type (and others in the file) to use right namespace.

To get namespace App\Entity\Club in return type you need use \App\Entity\Club (with leading slash) or Club (without leading slash)
