Symfony - 调用数组上的成员函数

Question

我有以下功能:

public function getUserMediaAction(Request $request)
{
    $data = $this->decodeToken($request);
    $username = $data['email'];
    $user = $this->getDoctrine()->getRepository('ApplicationSonataUserBundle:User')
                 ->findOneBy(['email' => $username]);
    $idUser = $user->getId();
    $media = $this->getDoctrine()->getRepository('ApplicationSonataUserBundle:User')
                  ->findNewbieAllData($idUser);

    return new JsonResponse(['media' => $media->getPath()]);
}

findNewbieAllData:

public function findNewbieAllData($id_newbie)
{
    $sql = "SELECT m
            FROM ApplicationSonataUserBundle:User u
            JOIN ApplicationSonataUserBundle:Media m
            WHERE u.id=?1";

    $query = $this->getEntityManager()

                    ->createQuery($sql)
                    ->setParameter(1, $id_newbie);

    $result = $query->getArrayResult();
    return $result;
}

不幸的是,它返回以下错误:

Call to a member function getPath() on array

Stack Trace

in src\CoolbirdBundle\Controller\UserController.php at line 97   -
        $media = $this->getDoctrine()->getRepository('ApplicationSonataUserBundle:User')
                      ->findNewbieAllData($idUser);
        return new JsonResponse(['media' => $media->getPath()]);
    }

请问有谁能解决这个问题吗？

先感谢您

请尝试以下方法：

return new JsonResponse(['media' => $media[0]->getPath()]);

编辑：查看输出，var_dump您应该尝试以下操作：

return new JsonResponse(['media' => $media[0]['path']]);
