Django request.POST.get does not save to model field - django

Question

I am trying to save data from request.POST dictionary. I would like to get the the 'name' value from request.POST which should correspond to the prefix. However, it does not happen and nothing gets saved to Name model. Also, I get no error. Could you please kindly advise how to solve this case? Thank you.

Answer 1

You should also pass "name=name" and "value={{formset.prefix}}" in your HTML form.
<input type="hidden" id={{formset.prefix}} name="name" value="{{formset.prefix}}" />

Answer 2

I figured out. The reason is that instance of the model was not created. Code should be as follows:
for form in formset:
assumption_data = form.save(commit=False)
assumption_data.Name = request.POST['name']
assumption_data.save()
where assumptions_data is an instance of Assumptions model. Thank you everyone for insights provided.
