How to assign roles on successful registration? - symfony

Question

I'm using fos user bundle and pugx multi user bundle.
I've read all the documentation and I'm new to Symfony.
In the pugx multi user bundle there's a sample on every point but one: sucessful registration.
Samples of overriding controllers for generating forms => ok
Samples of overriding templates for generating forms => ok
Samples of overriding successful registration sample => nothing.
Here's my code:
class RegistrationController extends BaseController
{
public function registerAction(Request $request)
{
$response = parent::registerAction($request);
return $response;
}
public function registerTeacherAction()
{
return $this->container
->get('pugx_multi_user.registration_manager')
->register('MyBundle\Entity\PersonTeacher');
}
public function registerStudentAction()
{
return $this->container
->get('pugx_multi_user.registration_manager')
->register('MyBundle\Entity\PersonStudent');
}
}
The problem is with ->get('pugx_multi_user.registration_manager') which returns a manager. In the fos user overring controllers help, they get either a form or a form.handler. I'm having hard times to "link" those with the pugx_multi_user manager.
What code should I put in the registerTeacherAction() to set roles for teacher, and in registerStudentAction() to set roles for student on a successful registration?

Solution 1 (Doctrine Listener/Subscriber)
You can easily add a doctrine prePersist listener/subscriber that adds the roles/groups to your entities depending on their type before persisting.
The listener
namespace Acme\YourBundle\EventListener;
use Doctrine\ORM\Event\LifecycleEventArgs;
use Acme\YourBundle\Entity\Student;
class RoleListener
{
public function prePersist(LifecycleEventArgs $args)
{
$entity = $args->getEntity();
$entityManager = $args->getEntityManager();
// check for students, teachers, whatever ...
if ($entity instanceof Student) {
$entity->addRole('ROLE_WHATEVER');
// or
$entity->addGroup('students');
// ...
}
// ...
}
}
The service configuration
# app/config/config.yml or load inside a bundle extension
services:
your.role_listener:
class: Acme\YourBundle\EventListener\RoleListener
tags:
- { name: doctrine.event_listener, event: prePersist }
Solution 2 (Doctrine LifeCycle Callbacks):
Using lifecycle callbacks you can integrate the role-/group-operations directly into your entity.
/**
* #ORM\Entity()
* #ORM\HasLifecycleCallbacks()
*/
class Student
{
/**
* #ORM\PrePersist
*/
public function setCreatedAtValue()
{
$this->addRole('ROLE_WHATEVER');
$this->addGroup('students');
}
Solution 3 (Event Dispatcher):
Register an event listener/subscriber for the "fos_user.registration.success" event.
