Linking failure in stylesheet_link_tag in production mode with asset pipeline enabled

Hey,

in my `application.html.erb`, I have this line:

    <%= stylesheet_link_tag 'application' %>

which should compile through the asset pipeline and link to the application.css (which does a `require_tree .`). In development mode, I'd expect a

    <link ... href="/assets/application.css" />

This file is actually delivered by, for example, the thin webserver.

When starting thin in production mode (even after `rake assets:precompile`), the `application.css` is still link'ed – here I'd expect the `/assets/application-md5hash.css` which is generated in the public directory. Even further: in the SCSS files, the `image_url` helper does not resolve the correct paths (cp. Module: Sass::Rails::Helpers — Documentation for sass-rails (3.1.0)),

   background: image_url('foo.png');

compiles to

   background: url(/assets/foo.png);

instead of

  background: url(/assets/foo-md5hash.png);

Or am I just missing something!?

Got it.

In my config/enviroments/production.rb, the following lines were missing:

    config.assets.compress = true     config.assets.compile = true     config.assets.digest = true

I actually was upgrading a 3.0 application and obviously missed some configs. Sorry for the noise!

(coincidentally, today's Railscast covers this issue – #282 Upgrading to Rails 3.1 - RailsCasts)
