Re: Need help to catch "cart_id" based on session.

I would try request.session.get('cart_id', None) instead of
request.session['card_id'].

Both act the same if the key exist in the dict. When the key is
missing, the first return the second value (None in this case) while
the second raise a Key Error exception.
