This is a test case for something tht puzzles me. I want to be able to create an application that has a set of STI models. I want to be able to create a select field with a choice of the types. If I just use "Parent.subclasses_of(Parent)", it fails. If I use the derived types, then use the same call, I see them. This is probably something to do with lazy loading of models... maybe. To see the problem, install the app, run the server and navigate to http://localhost:3000/parents to see the single defined view for this application. It has two variables, one holding the types seen before using them (none, in my case) and one holding the types seen after using them (both of them). I find this confusing. I probably don't know enough...
