Hi, so I'm setting up some models and they are based off of 2 abstract base classes (or rather they used to be classes). After running into a lot of trouble with Datamapper's handling of STI for my use case, which appears to be an open bug on their lighthouse page, I decided instead to just do modules to define all the properties to keep...
