I've found that adding a git pre–commit hook which compiles and packs assets, then adds them to the current commit comes in handy in this case.

rake barista:brew
git add public/assets/*
git add public/javascripts/*

Like this all your assets will be packed for you and you don't have to worry anymore about it.
