Rails Assets custom manifests are not precompiling

Question

I have a scenario as follows. I've built a "themed" site using the asset pipeline. There are a variety of manifests:

application.scss
application_light.scss
application_dark.scss

When I run rake assets:precompile, only application.scss gets compiled and created as application.css.

I have no trouble with these assets in development, it is only in production pre-compilation that they fail.

I have tried:

config.assets.precompile += %w( application_light.scss )

This also does not work, it simply does not precompile anything past application.scss

Answer 1

I found the answer here:

Precompiling a .scss manifest file using Rails 3.1's asset pipeline

Turns out I just needed to change the precompile to css from scss.
