Web application guide?

Hi,
Is there anything like a web application guide for xTuple? I am developing a web app in the python framework django. I've been able to set install the proper libraries to connect to postgresql and run a database introspection. This reverse engineers the tables into django Model classes (an object-relational mapping). So I have that to start with, but I've been advised that the best way to write apps for xTuple is to use the db views. I'm a little new to that, so I'm wondering if there's a guide somewhere to get me started.

Thanks,
JoeC

ps. If anyone else has used python/django in this way, would love to get connected!
