Django Model Form not displaying information stored in session
My views.py file class multi_form(View): model=Customer template_name='index.html' def get(self, request): form=RegForm() if request.session.has_key('pan_card_number'): first_name=request.session['first_name'] last_name=request.session['last_name'] personal_email=request.session['personal_email'] official_email=request.session['official_email'] permanent_address=request.session['current_address'] current_address=request.session['permanent_address'] pan_card_number=request.session['pan_card_number'] aadhar_card_number=request.session['aadhar_card_number'] loan_amount=request.session['loan_amount'] context = {'form': form} return render(request, 'customer/index.html', context) def post(self, request): form=RegForm() if request.method=='POST': form=RegForm(request.POST, request.FILES) if form.is_valid(): request.session['first_name']=form.cleaned_data['first_name'] request.session['last_name']=form.cleaned_data['last_name'] request.session['personal_email']=form.cleaned_data['personal_email'] request.session['official_email']=form.cleaned_data['official_email'] request.session['current_address']=form.cleaned_data['current_address'] request.session['permanent_address']=form.cleaned_data['permanent_address'] request.session['pan_card_number']=form.cleaned_data['pan_card_number'] request.session['aadhar_card_number']=form.cleaned_data['aadhar_card_number'] request.session['loan_amount']=form.cleaned_data['loan_amount'] form.save() messages.success(request, "Your Response has been recorded") return render(request, 'customer/index.html') context = {'form': form} return render(request, 'customer/index.html', context) What I want is the form to auto populate the fields filled earlier with those I have saved in django session variables.

Django: too many values to unpack (excpected 2) error (.objects.filter)
I am trying to remake the project alone that I've already finished with my team. What i want to do is to make the project almost the same with the one we've done. We worked with 3 apps-User, Product, Order-so this time again, I'll go with those 3 apps. And I decided to do it with the DB(going to call it 'old DB') that we've already built because whole environment of this project setting is just the same with the previous one. After connecting the old DB on settings.py, I wrote User app's views.py to try SignUp and SignIn API, and it didn't work. I realised that I didn't write other apps' models.py to make old DB work fine(because the old DB consists of info from all the apps we made-all three apps' models.py are connected to each other with foreign keys). So, I wrote every piece of models.py of all the apps(User, Product, Order) to figure out this issue. However, the same error occurs.
