Rails 3.2 development environment asset issue

I just tracked down and dealt with an issue I was having after upgrading to rails 3.2. After the upgrade assets (css, javascript) were not updating unless I restarted the server process. Took me a while to track down the issue but I finally tracked it down to asset fingerprinting. Asset fingerprinting is off by default in the development environment but I had turned it on to debug an issue a long time ago.

If you are having similar problems make sure that you have the following line in "config/environments/development.rb"

  config.assets.digest = false
