Symfony2: How to display admin-account name while impersonating user-account?

symfony, twig

Solution

With the idea you have proposed above,.. can you not just create a custom twig extension that encompasses your logic from your twig template so that you can just call `myCustomTwigFunction` within your twig template and it will output the original users name?

See http://symfony.com/doc/current/cookbook/templating/twig_extension.html for more info about custom twig extensions

The code you'd have in your Twig extension file would be...

$roles = $this->container->get('security.context')->getToken()->getRoles();
foreach ($roles as $role) {
    if (method_exists($role, 'getSource')) {
        return ($role->getSource()->getUser()->getUsername());
    }
}

Where $container is a class variable of the DI Container on your twig extension class

Problem

I want to display something like that: Case 1: "logged in as USER" @ UserName [ logout ] No problems here, i just do: @ {{ app.user.username}} [ <a href="{{ path("logout") }}">logout</a> ] Case 2: "logged in as ADMIN" @ AdminName [ logout ] The same works here: @ {{ app.user.username}} [ <a href="{{ path("logout") }}">logout</a> ] Case 3: "logged in as ADMIN impersonating a USER" AdminName @ UserName [ return ] Now thats a problem: {{ ??..what here..?? }} @ {{ app.user.username}} [ <a href="{{ (app.request.getRequestUri ~ '?_switch_user=_exit') }}">return</a> ] This is the only solution I know... it seems a lot of code for a sipmle displaying username :/ ``` {# iterating through user roles to find ROLE_PREVIOUS_ADMIN #} {% for role in app.security.token.roles %} {% if role.source is defined %} {{ role.source.user.username }} {% endif %} {% endfor %} @ {{ app.user.username }} [ <a href="{{ (app.request.getRequestUri ~ '?_switch_user=_exit') }}">return</a> ] ``` Is there any other way? I need a pure TWIG solution -> this is supposed to be part of my main twig template (that is extended by all other templates) -> I can't add controller code to all actions, just to display username.
