I cannot find out why I've got this error. Any idea?

Django 1.10 seems to have introduced a change that is causing the error.

The get_form inside the view needs to change as below
def get_form(self, form_class=None): if form_class is None: form_class = self.get_form_class()

Hey,
I got the same problem while migrating to Django 1.11.13. Setting the default to None results in a TypeError 'NoneType' object is not callable.

This is the Traceback:

I tried fixing it by adding these lines in the view:

    if form_class is None:
        form_class = QuestionForm

which results in an AttributeError claiming:
'Question' object has no attribute 'get_answers_list'

Any advice is much appreciated. Thank you.

Django 1.10 seems to have introduced a change that is causing the error.

The get_form inside the view needs to change as below
def get_form(self, form_class=None): if form_class is None: form_class = self.get_form_class()

which function exactly? I am having the same challenge
