Using Symfony2 assetic results in 404 - php

Question

I can't seem to get assetic to work with me.
Here is my assetic config in my config.yml file
assetic:
debug: "%kernel.debug%"
use_controller: false
bundles: [ FOSUserBundle, MyUserBundle ]
filters:
cssrewrite: ~
I have created a bundle that extends the FOSUserBundle. I've overridden the registration template and am trying to include my own css.
// MyUserBundle/Resources/views/Registration/register_content.html.twig
{% block stylesheets %}
{% stylesheets 'bundles/myuser/css/*' filter='cssrewrite' %}
<link rel="stylesheet" href="{{ asset_url }}" />
{% endstylesheets %}
{% endblock %}
My bundle has the following structure:
/MyUserBundle
...
/Resources
...
/public
/css
signup.css
I always get a 404 though.
http://myproject.dev/css/494d9ed_part_1_signin_1.css 404 Not Found.
I get the following exception thrown:
No route found for "GET /css/494d9ed_part_1_signin_1.css"
I've published the assets so it also lives in
/MyProject
/web
/bundles
/myuser
/css
signin.css
What am I doing wrong?

Answer 1

Try with this syntax:
{% stylesheets filter='cssrewrite' '#MyUserBundle/Resources/public/css/*' %}
<link rel="stylesheet" type="text/css" href="{{ asset_url }}" />
{% endstylesheets %}
and then on the command line:
php app/console cache:clear
php app/console assets:install --symlink
php app/console assetic:dump
In the DEV environment it should work without the assetic:dump command.
