Symfony - 調用數組上的成員函數

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，它返回以下錯誤：

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()]);
    }

請問有誰能解決這個問題嗎？

先感謝您

Answer 1

請嘗試以下方法：

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

編輯：看看var_dump輸出你應該試試這個：

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

Answer 2

方法findNewbieAllData使用數組findNewbieAllData水合數據。

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

在這里查看getArrayResult方法：

https://github.com/doctrine/doctrine2/blob/master/lib/Doctrine/ORM/AbstractQuery.php

請改用getResult方法。
