User 클래스의 get 메서드를 FOSUserBundle에서 상속 받고 싶습니다. 내 CONTROLER에서

Fatal error: Call to a member function getNom() on a non-object.

내 사용자 클래스 :하지만 난 오류가 당신이 메소드를 호출 할 수

public function invitationAction($token) 
{ 
    $em = $this->getDoctrine()->getEntityManager(); 
    $entity = $em->getRepository('OlrLoanBundle:User')->findBy(array('salt'=>$token)); 

    return $this->render('OlrLoanBundle:Tribu:invitation.html.twig', 
     array('nom'=>$entity->getNom(), 
       'prenom'=>$entity->getPrenom(), 
      )); 
} 

Answer 1

findBy()는 array 반환합니다.
