Unsubscribe users in FOSUserBundle - symfony

Question

I'm redesigning a website in symfony2, where users must be able to unsubscribe.
When they do, for database integrity reasons, we have to de-activate their account, and not completely delete it. We must also keep track of their personnal information, like email adress, for a certain time (legal obligation).
I'm using FOSUserBundle, and I initially thought a simple way to deactivate accounts of people who unsubscribed, would be to set the User property "enabled" to false.
But when a user is not enabled, if he tries to register again with the same email adress, he sees : "The email is already used". And I would like he could register again and create a new account (or reactivate the old one).
Is there a way to do this ?
Is there a best practice to handle unsubscriptions with FOSUserBundle ?
Thanks for your help.

Answer 1

You need to override the main registration process with, the easyextendbundle, you could have a look at the documentation at this url:
https://sonata-project.org/bundles/user/2-2/doc/reference/installation.html
Then in your extended controller, you have to create a new action to activate or deactivate your user, this action must be public in the security rules.
In this method, you could use the services to activate or deactivate a user:
fos:user:deactivate Deactivate a user
fos:user:activate Activate a user
You could inspire yourself from this earlier post : Symfony2: List Users with Option to Deactivate Each User

Answer 2

Another possibility is to update your User class with the property $subscribed as below:
/**
* #ORM\Column(name="subscribed", type="boolean")
*/
protected $subscribed;
public function setSubscribed($subscribed)
{
$this->subscribed = $subscribed;
}
public function isSubscribed($)
{
return $this->subscribed;
}
public function changeSubscribed()
{
$this->subscribed = !$this->subscribed;
}
This avoids e-mail address conflicts without adding another third-party bundle.
Edit (note also set method above)
in YourBundle\EventListener
use FOS\UserBundle\FOSUserEvents;
use FOS\UserBundle\Event\FormEvent;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
class RegistrationListener implements EventSubscriberInterface
{
public static function getSubscribedEvents()
{
return array(
FOSUserEvents::REGISTRATION_SUCCESS => 'onRegistrationSuccess',
);
}
/**
* Persist organization on staff registration success.
*
* #param \FOS\UserBundle\Event\FormEvent $event
*/
public function onRegistrationSuccess(FormEvent $event)
{
/** #var $user \FOS\UserBundle\Model\UserInterface */
$user = $event->getForm()->getData();
$user->setSubscribed(true);
}
}
also, add to app/config/services.yml:
your_bundle.regisration.listener:
class: YourBundle\EventListener\RegistrationListener
tags:
- { name: kernel.event_subscriber }
