Answer 1

You have to specify a subject_id to redirect since you have a <int:subject_id> in the path and the get method requires it.
#method_decorator(login_required, name='dispatch')
class Sections(View):
def post(self, request, subject_id):
sections =request.POST.get('section')
print(sections)
return redirect('subjects:section', subject_id=subject_id)
