Symfony 2 FosUser: Authenticate after registration - symfony

Question

I'm using FOSUserBundle together with NnmMultiUserBundle.
When a user register, using my form_handler, the User entity is created, and should automatically login this new user.
I haven't been able to make that automatic login works.
My Controller:
public function registerAction()
{
$discriminator = $this->container->get('nmn_user_discriminator');
$discriminator->setClass('Travelyo\UserBundle\Entity\UserFrontend');
$form = $discriminator->getRegistrationForm();
//$form = $this->container->get('fos_user.registration.form');
$formHandler = $this->container->get('fos_user.registration.form.handler');
$confirmationEnabled = $this->container->getParameter('fos_user.registration.confirmation.enabled');
$process = $formHandler->process($confirmationEnabled, array(User::ROLE_CUSTOMER));
if ($process) {
$user = $form->getData();
if ($confirmationEnabled) {
$this->container->get('session')->set('fos_user_send_confirmation_email/email', $user->getEmail());
$route = 'fos_frontend_registration_check_email';
} else {
$this->authenticateUser($user);
$route = 'fos_frontend_registration_confirmed';
}
$this->setFlash('fos_user_success', 'registration.flash.user_created');
$url = $this->container->get('router')->generate($route);
return new RedirectResponse($url);
}
return $this->container->get('templating')->renderResponse('TravelyoUserBundle:Registration:user_frontend.form.html.' . $this->getEngine(), array('form' => $form->createView(),));
}
Athenticate method:
protected function authenticateUser(UserInterface $user)
{
try {
$this->container->get('fos_user.user_checker')->checkPostAuth($user);
} catch (AccountStatusException $e) {
// Don't authenticate locked, disabled or expired users
return;
}
$providerKey = $this->container->getParameter('fos_user.firewall_name');
$token = new UsernamePasswordToken($user, null, $providerKey, $user->getRoles());
$this->container->get('security.context')->setToken($token);
}
After calling athenticate the controller redirects to ConfirmedAction, where it tries to get the "logged in" user:
public function confirmedAction()
{
$user = $this->container->get('security.context')->getToken()->getUser();
if (!is_object($user) || !$user instanceof UserInterface) {
throw new AccessDeniedException('This user does not have access to this section.');
}
return $this->container->get('templating')->renderResponse('FOSUserBundle:Registration:confirmed.html.'.$this->getEngine(), array(
'user' => $user,
));
}
Error message:
Fatal error: Call to a member function getUser() on a non-object in /Data/Web/Local/travelyo/vendor/bundles/FOS/UserBundle/Controller/RegistrationController.php on line 115
If I then try to login using the login form it works fine (meaning that the creation of the user is working). But I can't understand why this token cannot be retrieved from security.context.

Answer 1

Security context is (as described in symfony 2 doc) not shared across firewall.
My registration form was in the "public firewall" => /register.
When authenticating the user (right after the user is registered), the token is saved for the public security.context.
I was then redirected to my actual "account" firewall => /account, and no token was found in the security.context as the token had never been defined for that firewall.
In order to solve it I simply moved my registration process under the same firewall, and it now works like a charm.
But I would still assume it should be possible to set a token for another security.context, if anyone know how it might be useful.
Thanks!
