Django class-based CreateView and UpdateView with multiple inline formsets

Question

I have been trying to do Django class-based CreateView and UpdateView with multiple inline formsets

CreateView works fine but UpdateView is not working properly, If

Answer 1

My guess is that you can't do

self.object = None

on overwritten post method in a UpdateView. So, try

self.object = self.get_object()

instead, once you already have an object instance in this case.
