Answer 1

The original post might have been true back in 2009, but now it is actually incorrect now, and no linking is even required for the stylesheet as I see mentioned in some of the other responses. Rails will now do this for you by default.

• Place any new sheet .css (or other) in app/assets/stylesheets
• Test your server with rails-root/scripts/rails server and you'll see the link is added by rails itself.

You can test this with a path in your browser like testserverpath:3000/assets/filename_to_test.css?body=1

Answer 2

Use the rails style sheet tag to link your main.css like this

<%= stylesheet_link_tag "main" %>

Go to

config/initializers/assets.rb

Once inside the assets.rb add the following code snippet just below the Rails.application.config.assets.version = '1.0'

Rails.application.config.assets.version = '1.0'
Rails.application.config.assets.precompile += %w( main.css )

Restart your server.
