This might be a retarded question but how do I access things other than Models in rails console, such as Controller methods, engines etc.? I wouldn't mind seeing a video dedicated to console and the extent on what you can look up.
This page on the rails guide shows more things you can do
It looks like you have access to the app and helper methods as well.
What Andrew said! For some of the controller methods, you can sometimes just instantiate the class like any other normal object. The trouble will be that you don't have request objects to work with to pass in.
