ruby on rails - ActionView::Template::Error (960.css isn't precompiled)

Question

I have an iframe which renders a partial and is not part of the main application layout or asset pipeline.

I'd like to include some style sheets, however I am getting this error:

 ActionView::Template::Error (960sm.css isn't precompiled):

Rails 3.1 Heroku

Answer 1

Style sheets that are not included in a manifest (directly by name or indirectly via require_tree) are not precompiled, so will not accessible in production.

You need to add the sheet to the list of items to precompile in the environment application.rb.

config.assets.precompile += ['960sm.css']

And then access it in the view:

stylesheet_link_tag('960sm')
