When is a cached stylesheet refreshed in Rails ?

Question

In a Rails application, if I group several stylesheets into one using caching, will the resulting file be automatically refreshed when one of the stylesheets is updated ?

stylesheet_link_tag "style1.css", "style2.css", :cache => "mystyles"

And, if not, how can I expire the resulting file ?

Answer 1

For production environments, just delete all.css from your stylesheets driectory as part of your deployment to have it regenerated using the new files.

In development mode, ActionController::Base.perform_caching is false by default so no caching will happen.
