Hi Matt, Well the problem is that I require all the files (classes) in the user's folder at once so I don't know which one depends on the other. What I have seen is that when I copy them to the rails lib folder and start the server there are no problems loading the files and dependencies, that's why I want to know how rails does it.
What I'm doing is an app where users, as you guessed, can create their own ruby classes and write their code online. I know there are a lot of issues that may arise, can you give me any good approach I can take (not only for this but for what I stated above).
