I'm having a Rails 3.1 rc6 app on Heroku's cedar stack (ruby 1.9.2).
I precompile assets using rake assets:precompile RAILS_ENV=production locally on my development machine.
The problem is the generated md5 fingerprints in the precompiled filenames don't match the ones generated by the rails helpers (like asset_path) in production on Heroku.
Does anyone have a clue why this is? How can I fix it? I can't precompile on Heroku, as they have a read only filesystem.
