This seems like it should be really obvious, but I'm clearly missing something. I have a model in a rails app, and I want to quickly run through a method using breakpoints etc. If I simply debug the ruby script that is my model, the environement doesn't load so I get an error. If I switch to the development config the server loads and then nothing happens and I can't figure out how to just step through my model? This seems like it'd be the simplest thing but I can't figure it out.
