Symfony2 - Redirection after successful login - authentication

Question

I've just started working through the Symfony 2 tutorials. I have created a bundle with a user class and have tried to follow the instructions to set up a login process. I think I am nearly there, however I'm currently falling at the last hurdle.
I have set up a bundle: Dan\AuthBundle, which contains my user class and another bundle: Dan\HelloBundle which I want to allow only logged in users to access.
My security.yml file is as follows:
security:
encoders:
Dan\AuthBundle\Entity\User: sha512
providers:
main:
entity: { class: Dan\AuthBundle\Entity\User, property: username }
administrators:
entity: { class: DanAuthBundle:User }
firewalls:
secured_area:
pattern: ^/*
form_login:
check_path: /login_check
login_path: /login
always_use_default_target_path: false
default_target_path: /hello
access_control:
- { path: ^/hello/.* }
The main routing.yml file looks like this:
DanAuthBundle:
resource: "#DanAuthBundle/Resources/config/routing.yml"
prefix: /auth/
DanHelloBundle_homepage:
pattern: /hello/
defaults: { _controller: DanHelloBundle:Default:index }
login:
pattern: /login
defaults: {_controller: DanAuthBundle:Default:login }
login_check:
pattern: /login_check
I have created several instances of my user class manually.
If I try to access the url /hello, I correctly get redirected to the login page. If I enter incorrect details, I get the correct message(s) delivered in the template, however, when I log in with the correct details, I receive a 324 (empty response) error (at this time, the url displayed in the browser is login_check).
From reading the documentation, I thought I should be redirected to the page I was originally trying to access?
http://symfony.com/doc/current/book/security.html#using-a-traditional-login-form
By default, if the submitted credentials are correct, the user will be
redirected to the original page that was requested (e.g. /admin/foo).
If the user originally went straight to the login page, he'll be
redirected to the homepage. This can be highly customized, allowing
you to, for example, redirect the user to a specific URL.
Also, if I try to access the page after entering the correct details, I once again get redirected to the login page.
Can anyone see if I've missed anything obvious?
This is from my log file:
[2012-06-18 18:33:47] doctrine.DEBUG: SELECT t0.id AS id1, t0.username
AS username2, t0.salt AS salt3, t0.hashed_password AS hashed_password4

Any advice appreciated.
Thanks.

Answer 1

// if you're using Symfony 2.0
$key = '_security.target_path';
// if you're using Symfony 2.1 or greater
// where "main" is the name of your firewall in security.yml
$key = '_security.main.target_path';
// try to redirect to the last page, or fallback to the homepage
if ($this->container->get('session')->has($key)) {
$url = $this->container->get('session')->get($key);
$this->container->get('session')->remove($key);
} else {
$url = $this->container->get('router')->generate('homepage');
}
return new RedirectResponse($url);

Answer 2

You need 2 listeners.
One to set in session last page
Second to redirect after succesfull login

Answer 3

just use getUser check in your respective action (where you are rendering the login form view) as below:
if($this->getUser()){
return $this->redirect($this->generateUrl('your-redirect-path-alise'));
}
