如何在findAll（）的indexAction端使用findById？

Question

我试图编辑我的indexAction函数，我想为用户

找到BYOne

public function indexAction() {
    $em = $this->getDoctrine()->getManager();
    if ($this->isGranted('ROLE_ADMIN')) {
        $leaveRequests = $em->getRepository('AppBundle:LeaveRequest')->findAll();
    } else {
        $leaveRequests = $em->getRepository('AppBundle:LeaveRequest')->findOneBy(['id‌​' => $id]);
    }

    return $this->render('leaverequest/index.html.twig', array(
        'leaveRequests' => $leaveRequests,
    ));
}

我收到以下错误

  

注意：未定义的变量：id

我看过实体，但没找到任何东西。 这是我的实体：

编辑：从实体添加缺失的部分作为代码。在此先感谢任何人为此添加答案。

您正在尝试使用未定义的变量（如通知所说）

以下是您可以做的一个示例：

public function indexAction() {
    $user   = $this->getUser();
    $userId = $user->getId();
    $em = $this->getDoctrine()->getManager();
    if ($this->isGranted('ROLE_ADMIN')) {
        $leaveRequests = $em->getRepository('AppBundle:LeaveRequest')->findAll();
    } else {
        // I admit that in your LeaveRequest entity you have a relation with your User Entity which name is 'userId'
        $leaveRequests = $em->getRepository('AppBundle:LeaveRequest')->findOneBy(['userId​' => $userId]);
    }

    return $this->render('leaverequest/index.html.twig', array(
        'leaveRequests' => $leaveRequests,
    ));
}

此致
