To share code between models, you have the same two choices that you have for sharing code between *any* classes (remember, there's nothing magical about models): 1. Put it in a module and include it in the models you want to use it, or 2. Create a subclass of ActiveRecord, put the code there, and have the models inherit from that.

You just need to remember that inheritance and module inclusion are fundamental Ruby tricks that should be on your radar.
