I'm working on techniques that help you safely refactor your Rails codebase. At the start I'm mostly focusing on the Rails controllers. You can sign up at http://rails-refactoring.com/ for free rails refactoring lessons. Meanwhile, please send me more examples of Rails controllers, so that I can discover better patterns. andrzejkrzywda@gmail.com
