Ok...on to a new problem. I'm able to add stuff to my session and
also delete the entire sesssion. However, I'm not sure how to delete
a particular entry into my session variable. This is how i add stuff
to my session
cart = request.session.get('cart', [])
cart.append({'style': s, 'choice': c})
What method do I use on request.session to delete only one "row" in my
cart dictionary? Does cart have an id field that I can access?
Thanks
