可捕获的致命错误:传递给控制器的参数 1::__construct() 必须是 DoctrineORMEntit

        //$em = $this->getDoctrine()->getManager();
        return new Response(json_encode("hi")); 
 }
}

在树枝文件中

 {% set notification_html = render(controller('MainAdminBundle:Notification:notificationlist',{"notification_for":"organization","notification_to":"1","lang_id":"1"})) %}

基本控制器

class BaseController extends Controller{
public function __construct()
{
    date_default_timezone_set("Asia/Calcutta");
 }
}

我在使用 Twig file( as above ) 调用通知列表操作时收到此错误

可捕获的致命错误:参数 1 传递给控制器::__construct() 必须是 Doctrine''ORM''EntityManager 的实例,没有给出,称为

如果我删除实体管理器,那么我在创建操作中出现错误 喜欢

错误:对非对象上的成员函数 has() 的调用

因为我用这个调用这个创建操作

$notification = new NotificationController($em);
$notification_id = $notification->notificationcreateAction('appointment_book','New  Appointment');

所以我必须添加实体管理器.

首先,解决这个特定的错误情况。如果您的问题包含整个 NotificationController,则似乎不需要定义构造函数将元素管理器存储在类变量中 - 您的 notificationcreateAction 从 doctrine 中获取实体管理器实例,并且不使用类变量。即完全删除构造函数和类变量:

class NotificationController extends BaseController
{
    protected $session;
    /**
     * @Route("/Notification1/{salon_id}",defaults={"salon_id":""})
     * @Template()
     */
    public function indexAction($salon_id)
    {
        return array("j"=>"jj");
    }
    // and so forth...

并更新您在控制器上使用的代码,以便:

$notification = new NotificationController();
$notification_id = $notification->notificationcreateAction('appointment_book','New  Appointment');

更笼统地回答这个问题

不应在不同的控制器中实例化控制器。相反,您应该为公共代码创建一个可以从所有控制器调用的服务。更多关于symfony服务:服务容器
