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;
}

遗憾地返回以下错误：

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()]);
    }

有人会知道如何解决这个问题吗？

提前谢谢

Answer 1

请尝试以下方法：

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

修改：查看var_dump输出，您应该尝试这样做：

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

Answer 2

方法findNewbieAllData使用数组来水合数据。

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

在这里查看getArrayResult方法：

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

改为使用getResult方法。

Symfony - 调用数组上的成员函数
