Guide to write test for django model, view and forms

[noobplusplus]

I am new to BDD, but having fair amount of experience in writing unittest and functional test(selenium). I want to try hands on lettuce with django. I could not find a decent getting started for django forms, models and views. What would be a good way to start of with and go ahead, let me know the resources/docs. 

Also would be good, if people tell me some good libraries to use alongside. 

I have read the following: http://lettuce.it/recipes/django-lxml.html
