Issue
I am trying to add a set of inline forms, but when I try to save the information of the forms it throws me this error
views.py
The intention is to create more orders for a particular client, for that reason I focus on the "createOrder" function to achieve it.

delivered_value = orders_value.filter(status='Delivered').count()

Exception Type: AttributeError at /create_order/1
Exception Value: 'WSGIRequest' object has no attribute 'get'
I think it has to do with the way the information is managed from the template, but I'm not really sure. Can someone help me?
Solution
Change:
OrderFormSet(request, instance=customer)
to:
OrderFormSet(request.POST, instance=customer)
The formset requires the post data, not the request object.
