Symfony2相当于before_filter？

Question

Just wondering if Symfony2 has an equivalent to before_filter from Rails? I want to alter the layout of my application based on the type of user that is viewing it. Thanks a lot.

EDIT: I should clarify my question. I want to alter the layout of my application based on a URL parameter. So ultimately all the before_filter equivalent has to do is make every template rendered by the controller inherit from a different base template based on that URL parameter. I should add I already have over 50 controller actions that render templates so ideally the solution should be something that is easy to enable application-wide without having to edit every controller action.

I don't know that function but you can try {% if is_granted('ROLE_XXX') %} in twig templates or $this->get('security.context')->isGranted('ROLE_ADMIN') in the controller

You'll find more information in http://symfony.com/doc/current/book/security.html.

Hope this helps.
