Hi Keith,

Looks like o.__setattr__(f, data[f]) is not doing it's job for the
field down_payment_assets. You might want to print or log what's in
'data' before you iterate over it.
Also, are you aware that Django's built-in ModelForm provides similar
functionality to what you seem to be trying to achieve above?
