Dynamic SASS is a Rails Engine (so only rails 2.3 and above) that renders your SASS templates on each request. This is handy for platforms like heroku which have a read only file system, but run behind a caching proxy server anyway.
- Install the plugin, you should know how to do that by now.
- Make sure it loads immediately after haml (it has to undo some of HAML's work).
Add the following lines to your environment.rb near the end of the initializer block:
config.gem "cwninja-dynamic_sass", :source => "http://gems.github.com/", :lib => false
config.plugins = ["haml", "cwninja-dynamic_sass", :all]
And your done.
You should ensure that all generated css is removed when testing, and is not generated during testing.
