Path to web directory and assets in .js files in symfony2

Question

I'm googling and googling and can't find what I need.

How to get path to "web" directory in symfony2 in

• action [no idea, i only found solution for older versions of symfony:
  $sf_relative_url_root = sfContext::getInstance()->getRequest()->getRelativeUrlRoot();
  I've tried also $this->get('security.context')->getRequest()->getRelativeUrlRoot(), but it doesn't work]

• .js file

In case of .js file I do for now in twig template something like that:

<script type="text/javascript">
var asset_url="{{asset(' ')}}"; 
asset_url = asset_url.substr(0, asset_url.length-1);
</script>
<script href="{{asset('js/script.js')}}" type="text/javascript"></script>

is a better way?

If I understood your question correctly, then what you're looking for is $this->getRequest()->getUri() in a controller class.

Take a look at Symfony\Component\HttpFoundation\Request class if it's not, you will most likely find it there.
