Symfony simple login - symfony

Question

i to do login in my webpage about symfony documentation example and i have a little problem. It's work but work a second time, after i clear cache. In first time i catch error with your session time out or you disabled cookie.
it's base.html.twig
{% if is_granted('ROLE_USER') %}
<div class="content">
<div class="starter-template">
{% block body %}{% endblock %}
</div>
</div>
{% else %}
<div class="container">
<div class="row">
<div class="col-md-offset-5 col-md-3">
<div class="form-login">
<h4>Welcome back.</h4>
<form action="{{ path('login') }}" method="post">
<input type="text" name="_username" id="userName" class="form-control input-sm chat-input" placeholder="username" />
</br>
<input type="password" name="_password" id="userPassword" class="form-control input-sm chat-input" placeholder="password" />
</br>
<div class="wrapper">
<span class="group-btn">
<button type="submit" href="#" class="btn btn-primary btn-md">login <i class="fa fa-sign-in"></i></button>
</span>
</div>
</form>
</div>
</div>
</div>
</div>
{% endif %}
and login action:
/**
* #Route("/login", name="login")
*/
public function loginAction(Request $request)
{
$authenticationUtils = $this->get('security.authentication_utils');
$error = $authenticationUtils->getLastAuthenticationError();
$lastUsername = $authenticationUtils->getLastUsername();
return $this->render('security/login.html.twig', array(
'last_username' => $lastUsername,
'error' => $error,
));
}
I try return redirect in this action but nothing helps me.
If login to do in /login page it's work okey. But I want use with which construction how in base.html

Answer 1

Try work on dev mode.
1) Go on web directory
2) Open app.php file
3) Change the code inside app.php to
$kernel = new AppKernel('dev', true);
$response = $kernel->handle($request);
$response->send();
$kernel->terminate($request, $response);
Remove from controller
/**
* #Route("/login", name="login")
*/
Finally try move route in routing file.
For example in routing.yml:
login:
path: /login
defaults: { _controller: YourNameBundle:NameYourController:login }
