Question

I am currently working witn Rails 3.1. I need to use only one css file but the problem is that when I add the

<link href="http://mydomain.net/assets/some.css"></link>

it doesn’t exist. I need to get the css files from that particular css file and no other css files should be loaded.

How do I do that in Rails 3.1?

Update:

Adding this to production.rb:

config.assets.precompile += ['some.css']

causes the following error:

 ** [out :: domain.net] rake aborted!
 ** [out :: domain.net] stack level too deep
 ** [out :: domain.net] (in /home/deployer/apps/domain/releases/20120410204601/app/assets/stylesheets/some.css.scss)
 ** [out :: domain.net] 
 ** [out :: domain.net] Tasks: TOP => assets:precompile:primary
 ** [out :: domain.net] (See full trace by running task with --trace)

Update #2:

the filename for some.css is actually some.css.scss.

Update #3:

I just discovered the problem and it is caused by this:

Answer 1

As you are in production environment, all your assets must be precompiled, i.e. turned into static files and copied to /public.

In production all your individual files in app/assets are not directly accessible because they are not precompiled. Your individual css files are not precompiled when you run

rake assets:precompile

According to the asset pipeline documentation:

If you have other manifests or individual stylesheets and JavaScript
files to include, you can add them to the precompile array:

So for you, add a manifest header at the top of your css file:

/*
 *= require_self
 */

And then add in your config:

config.assets.precompile += ['some.css']

Then precompile your assets and access your css file as usual:

<%= stylesheet_link_tag 'some' %>

The answer is essentially correct if only sass-rails 3.1.5 didn’t have any issues. So I accepted the answer.
