Catchable Fatal Error: Argument 1 passed to Controller::__construct() must be an instance of Doctrine\ORM\EntityManager, none given, called

Notification controller 

<?php
namespace Main\AdminBundle\Controller;
/* included related namespace */
use Symfony\Component\PropertyAccess\PropertyAccess;
use Doctrine\ORM\EntityManager;
use Doctrine\ORM\Query;

use Main\AdminBundle\Entity\Notificationmaster;

class NotificationController extends BaseController
  {
      protected $session;
       protected  $em;

public function __construct(EntityManager $em)
{
    $this->em = $em;
}

/**
 * @Route("/Notification1/{salon_id}",defaults={"salon_id":""})
 * @Template()
 */
public function indexAction($salon_id)
{
        return array("j"=>"jj");
}

/**
 * @Route("/Notification/create/{notification_type}/{notification_title}",defaults={"notification_type":"","notification_title":""})
 */
public function notificationcreateAction($notification_type,$notification_title)
{
    //$this->em = $em;

        $notificationmaster = new Notificationmaster();     
        $notificationmaster->setNotification_type($notification_type);
        $notificationmaster->setNotification_title($notification_title);
        $em = $this->getDoctrine()->getManager();
        $em->persist($notificationmaster);
        $em->flush();           
        return $notificationmaster->getNotification_master_id();    
}   
/**
 * @Route("/Notification/List/{notification_for}/{notification_to}/{lang_id}",defaults={"notification_for":"","notification_to":"","lang_id":""})
 */
 public function notificationlistAction($notification_for,$notification_to,$lang_id)
 {
        //$em = $this->getDoctrine()->getManager();
        return new Response(json_encode("hi")); 

 }
}

in twig file 

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

Base Controller

class BaseController extends Controller{

public function __construct()
{
    date_default_timezone_set("Asia/Calcutta");
 }
}

i got this error while i m calling notification list action using Twig file( as above )

Catchable Fatal Error: Argument 1 passed to Controller::__construct() must be an instance of Doctrine\ORM\EntityManager, none given, called

if i remove entity manager , then i got an error in create action Like

Error: Call to a member function has() on a non-object

because i call this create action using this 

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

so i have to add entity manager .

First of, to address this particular error case. If you question contains the whole NotificationController, there doesn't seem to be any need to define a constructor nor having the element manager stored in class variable - your notificationcreateAction fetches the entity manager instance from doctrine and doesn't use the class variable. I.e. just remove the constructor and class variable completely:

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...

And update your the code you use on your controller to:

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

To answer the question more generically

You shouldn't be instantiating controllers in different controllers. Instead you should create a service for your common code that you can call from all of your controllers. More about symfony services: Service Container
