About FOSUserBundle User Manager

In order to be storage agnostic, all operations on the user instances are handled by a user manager implementing FOS\UserBundle\Model\UserManagerInterface. Using it ensures that your code will continue to work if you change the storage. The controllers provided by the bundle use the configured user manager instead of interacting directly with the storage layer.

If you configure the db_driver option to orm, this service is an instance of FOS\UserBundle\Doctrine\UserManager.

If you configure the db_driver option to mongodb, this service is an instance of FOS\UserBundle\Doctrine\UserManager.

If you configure the db_driver option to couchdb, this service is an instance of FOS\UserBundle\Doctrine\UserManager.

If you configure the db_driver option to propel, this service is an instance of FOS\UserBundle\Propel\UserManager.

Accessing the User Manager service

The user manager is available in the container as the fos_user.user_manager service.

$userManager = $container->get('fos_user.user_manager');

Creating a new User

A new instance of your User class can be created by the user manager.

$user = $userManager->createUser();

$user is now an instance of your user class.

Note:

This method will not work if your user class has some mandatory constructor arguments.

Retrieving the users

The user manager has a few methods to find users based on the unique fields (username, email and confirmation token) and a method to retrieve all existing users.

  • findUserByUsername($username)
  • findUserByEmail($email)
  • findUserByUsernameOrEmail($value) (check if the value looks like an email to choose)
  • findUserByConfirmationToken($token)
  • findUsers()

Updating a User object

To save a user object, you can use the updateUser method of the user manager. This method will update the encoded password and the canonical fields and then persist the changes.

<?php
//...
$user = $userManager->createUser();
$user->setUsername('John');
$user->setEmail('john.doe@example.com');

$userManager->updateUser($user);

Note:

To make it easier, the bundle comes with a Doctrine listener handling the update of the password and the canonical fields for you behind the scenes. If you always save the user through the user manager, you may want to disable it to improve performance.

In YAML:

# app/config/config.yml
fos_user:
    # ...
    use_listener: false

Or if you prefer XML:

# app/config/config.xml
<fos_user:config
    db-driver="orm"
    firewall-name="main"
    use-listener="false"
    user-class="MyProject\MyBundle\Entity\User"
/>

Warning:

The Propel implementation does not have such a listener so you have to call the method of the user manager to save the user.

Note:

For the Doctrine implementations, the default behavior is to flush the unit of work when calling the updateUser method. You can disable the flush by passing a second argument set to false. This will then be equivalent to calling updateCanonicalFields and updatePassword.

An ORM example:

<?php
public function MainController extends Controller
{
    public function updateAction($id)
    {
        $user = // get a user from the datastore

        $user->setEmail($newEmail);

        $this->get('fos_user.user_manager')->updateUser($user, false);

        // make more modifications to the database

        $this->getDoctrine()->getManager()->flush();
    }
}

Overriding the User Manager

You can replace the default implementation of the user manager by defining a service implementing FOS\UserBundle\Model\UserManagerInterface and setting its id in the configuration. The id of the default implementation is fos_user.user_manager.default

In YAML:

fos_user:
    # ...
    service:
        user_manager: custom_user_manager_id

Your custom implementation can extend FOS\UserBundle\Model\UserManager to reuse the common logic.

SecurityBundle integration

Although the built-in user managers also implement Symfony\Component\Security\Core\User\UserProviderInterface using the UserManager as user provider is deprecated and will trigger an error. Use 'FOS\UserBundle\Security\UserProvider' instead.

Something went wrong with that request. Please try again.
