In that case, what must I add to `models.py`? If this was pure Django, it 
seems I'd need to add a dictionary of fields, including `form_ptr`. But 
what's the correct way in Mezzanine?

[mezzanine-users] Re: No Payment step when $0

[Josh B]

If someone comes across this in the future the solution we came up with is 
as follows:
1. If the cart is a $0 cart
2. Hide the payment fields and use javascript to populate them with fake 
data. This way the form will pass validation.
3. Add a check in the payment process step to no process the card if the 
cart is $0
