Symfony: Variable "user" does not exist - php

Question

I get the variable does not exist error everytime I try to access a site on my blog.
the twig template:
{% extends '::base.html.twig' %}
{% block body %}
<div class="panel panel-default">
<div class="panel-heading">
<h3 class="panel-title text-center">All Users</h3>
</div>
<table class="table table-striped">
<thead>
<tr>
<th>Username</th>
<th>Email Address</th>
<th>Password</th>
</tr>
</thead>
<tbody>
{% for user in userlist %}
<tr>
<td>{{ user.username }}</td>
<td>{{ user.email }}</td>
<td>{{ user.password }}</td>
</tr>
{% endfor %}
</tbody>
</table>
</div>
<button type="button" class="btn btn btn-info">
Edit profile
</button>
{% endblock %}
the Controller :
<?php
// src/BlogBundle/Controller/UserController.php
namespace BlogBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Security;
use BlogBundle\Entity\Blog;
use BlogBundle\Entity\User;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpFoundation\Request;
class UserController extends Controller
{
/**
*#Security("has_role('ROLE_ADMIN')")
* #Route("/users", name="users", requirements={"page": "\d+"})
*/
public function listAction()
{
$user = $this->getDoctrine()->getRepository('BlogBundle:User')->findBy(array(), array('username' => 'DESC'));
dump($user);
return $this->render('BlogBundle:user:userlist.html.twig', [
'userlist' => $user
]);
}
/**
* #Route("/users/edit/{id}", name="edit", requirements={"id" = "\d+"}, defaults={"id" = 0})
*#Security("has_role('ROLE_ADMIN')")
*/
public function editAction(Request $request, User $user) {
$em = $this->getDoctrine()->getManager();
$user = $em->getRepository('BlogBundle:User')->find($username);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$em->persist($user);
$em->flush();
return $this->render('BlogBundle:user:userlist.html.twig', array(
'user' => $user,
'form' => $form->createView(),
'success' => true
));
}
return $this->render('FOSUserBundle:Profile:edit.html.twig');
}
public function configureOptions(OptionsResolver $resolver) {
$resolver->setDefaults([
'data_class' => 'BlogBundle\Entity\User'
]);
}
}
?>
and finally the User Entity:
<?php
// src/BlogBundle/Entity/User.php
namespace BlogBundle\Entity;
use FOS\UserBundle\Model\User as BaseUser;
use Doctrine\ORM\Mapping as ORM;
/**
* #ORM\Entity
* #ORM\Table(name="fos_user")
*/
class User extends BaseUser
{
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
public function __construct()
{
parent::__construct();
}
/**
* Get the value of Id
* #return mixed
*/
public function getId() {
return $this->id;
}
}
What I'm trying to do is, create a page that only the admin can access which displays a list of all users from my doctrine database. --> listAction()
next to that I would like to have the possibility to edit all the users information --> editAction()
any ideas?
the error occurs in the twig template line: "{{ path('edit', {'id':user.id}) }} ...

You put the button outside your loop, so yes, the variable user doesn't exist, simply put put
<button type="button" class="btn btn btn-info">
Edit profile
</button>
in the for loop
