How to use absolute path in twig functions

Question

I have an application with Symfony2 (2.2). When I want to send a mail, I\'m having trouble with the paths, which are all relative paths and obviously aren\'t working inside

Answer 1

It's possible to have http://test_site.com and https://production_site.com. Then hardcoding the url is a bad idea. I would suggest this:

{{app.request.scheme ~ '://' ~ app.request.host ~ asset('bundle/myname/img/image.gif')}}
