There might be times where you want to test out how the hashing and cache busting of your asset files might effect things in your app. For me I needed to check if my localStorage caching of font style sheets would work like I expect.
It's not that hard to enable this in development. You just need to set a couple of flags in your
config.assets.compress = true config.assets.compile = true config.assets.digest = true
Then restart your server. Now you should have nice MD5 hashed file names!
