symfony2 form is not displaying

Question

I am learning symfony2 and i have created one form in controller which is as bellow. the controller file as DefaultController.php

namespace Banner\TestBundle\Controller;

use Banner\TestBundle\Entity\Contact;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Banner\TestBundle\Entity\Task;
use Symfony\Components\HttpFoundation\Request;

class DefaultController extends Controller
{
public function newAction(Request $request)
{

 echo "The controller is called ";
 $task = new Task();
 $task->setTask("Write a blog Post ");
 $task->setDueDate(new DateTime('tomorrow'));

 $form =  $this->createFormBuilder($task)
            ->add('task','text  ')
            ->add('duedate','date')
            ->getForm();
    return $this->render('BannerTestBundle:default:zoo.html.twig',array('form'=>$form->createView()));

}
}

my routing file is as below. routing.yml

task_new:
pattern:  /task/{request}
defaults: { _controller: BannerTestBundle:Default:new}

and the zoo.html.twig file is as bellow.

{% extends '::page.html.twig' %}
    {% block title %}The Zoo{% endblock %}

    {% block content %}

        <form action="{{ path('task_new') }}" method="post" {{ form_enctype(form) }}>
                {{ form_widget(form) }}
            <input type="submit">   
        </form> 

    {% endblock %}

as i am passing the "task/GET" in my url it will shows the 'Request does not exist. error 500'.

what i basically want to do is when i pass the url the zoo.html.twig will be called. i want to display the form in zoo.html.twig.

You don't need to pass $request to your action and you don't need to put it in your route. The request object is available in global context. So

task_new:
    pattern:  /task-new
    defaults: { _controller: BannerTestBundle:Default:new}

You can either leave it this way

public function newAction(Request $request)

or have

public function newAction()

and access request object like this

$request  = $this->getRequest();

Your routing file is not properly indented so the yaml will not parse properly. Try:

task_new:
    pattern:  /task/{request}
    defaults: { _controller: BannerTestBundle:Default:new}

Also:

It is probably a bad idea to override request that way
You don't appear to be doing anything with request in your controller
