Restores the generation of non-digest assets from Rails 3. This is essential for when those assets must be referenced outside of Rails. Maybe some of your app in in another language, or maybe some of your JavaScript is dynamically and conditionally loaded.
Compile your assets with the regular task:
rake assets:precompile
This appends the standard task so that after doing the normal compile it copies all the fingerprinted files to non-fingerprinted files restoring the behavior of Rails 3.
Place this file in lib/tasks/ (or any other directory where tasks are picked up).
Based on all of the good ideas above, I put this together. Quick 2-3 seconds to check for missing links, then 1/2 second to create each one. Should work well as long as you don't have a lot of change on each deploy. Good luck!
