Django: ModelForm doesn't submmit - django

Question

I've a 2 steps form. Actually these are 2 forms. The first one lets me capture size and quantity variables from rendered ChoiceFields and save them in session.
2nd Form: renders a FileField and a CharField; and on submit is supposed to retrieve the size and quantity stored in session.
So at the end I'm submitting a record of SizeQuantity model with 5 fields: product (ForeignKey to Product model), size, quantity, image (making this optional - null True / blank True to discard its causing any troubles), comment (optional).
However, my when I click on the form submit button, on StepTwoForm (2nd form and final) my form doesn't submit -and therefore does not save a record in DB, I don't see any entering by the admin (model is registered).
The page just stays there, and the if image is uploaded this field gets empty in the html.

In your get_initials function ,
def get_initials(self):
# pre-populate form if someone goes back and forth between forms
initial = super(StepOneView, self).get_initials() #mispelled
You have mispelled the function call in the super
