Symfony: How do I refresh the authenticated user from the database?

Question

Say for example I grant a new role to the currently authenticated user in a controller, like so:

$em = $this->getDoctrine()->getManager();
$loggedInUse

While an answer is accepted, Symfony actually has a native way to refresh the User object. Credit goes out to Joeri Timmermans for this article.

Steps for refreshing the User object:

1. Make your User entity implement the interface

Symfony\Component\Security\Core\User\EquatableInterface

2. Implement the abstract function isEqualTo:

public function isEqualTo(UserInterface $user)
{
    if ($user instanceof User) {
        // Check that the roles are the same, in any order
        $isEqual = count($this->getRoles()) == count($user->getRoles());
        if ($isEqual) {
            foreach($this->getRoles() as $role) {
                $isEqual = $isEqual && in_array($role, $user->getRoles());
            }
        }
        return $isEqual;
    }

    return false;
}

The code above refreshes the User object if any new roles are added. The same principle also holds true for other fields you compare.
