I clearly must be Doing Something Wrong here. I'm wrestling with the asset pipeline (again). I have a custom font, and it seems to me to get everything to compile properly I need to use asset_path() in multiple places, but it's having an unexpected effect.
I realize there are several ways to do this, but here's what I have currently:
In application.css.scss.erb:
@import "<%= asset_path("my-font.css") %>";
my-font.css's source file is app/assets/stylesheets/my-font.css.erb (it needs to be an .erb because I am also using asset_path() there as well).
In application.rb I am adding my-font.css to the precompile list.
config.assets.precompile << 'my-font.css'
When I clean out public/assets and run rake assets:precompile Everything's getting compiled, with digests, but the digest applied to the actual file is not the same as the digest calculated and put in to application.css.
The resulting file is
public/assets/my-font-2f25682a1ea904a866ef9f44101a5a2e.css but in public/assets/application-bba2edaee36771f4bdb5c89b8ec90aaf.css the reference to it is:
@import url(/assets/my-font-ed843d3b174ca427edf963e473ad9e9b.css);
I realize I'm probably using asset_path() more than I should, and also importing files via url() instead of requiring them, but this has gotten me the closest to having things working.
I suspect one of the digests is being calculated on my-font.css before it goes through ERB, and the other after, but I don't understand why nor how to fix it.
Suggestions?

The asset pipeline provides a framework to concatenate and minify or compress JavaScript and CSS assets. It also adds the ability to write these assets in other languages such as CoffeeScript, Sass and ERB. Prior to Rails 3.1 these features were added through third-party Ruby libraries such as Jammit and Sprockets.
The Rails asset pipeline provides an assets:precompile rake task to allow assets to be compiled and cached up front rather than compiled every time the app boots. There are two ways you can use the asset pipeline on Heroku. Compiling assets locally. Compiling assets during slug compilation.
The require_tree directive tells Sprockets to recursively include all JavaScript files in the specified directory into the output. These paths must be specified relative to the manifest file.
I would guess that you're cleaning your assets just by emptying public/assets. That's not enough, you'll also need to empty your tmp/cache/assets, or just run rake assets:clobber to do both.
