Get ROLE of a user not logged in TWIG Symfony2

Question

I would like to know how can i know if a user is granted when it\'s not the current user in twig.

I use this code for the current user:

{% if is_gran

I think it would be much easier if you implemented an isGranted function in the User entity:

Class User implements UserInterface {
    ...
    public function isGranted($role)
    {
        return in_array($role, $this->getRoles());
    }
}

You can now easily check for granted roles in every layer of your application. In PHP:

$user->isGranted("USER_ADMIN")

Or in Twig:

user.granted("USER_ADMIN")

If you need to check a role for the current user, you can do this in Twig:

app.user.granted("USER_ADMIN")

Note: the variable "app" is globally defined.

Note 2: this code may throw an exception if you use it outside the secured area of your app, since app.user would be NULL.
