Django Form Wizard to Edit Model

Question

I have a Django form wizard working nicely for creating content of one of my models. I want to use the same Wizard for editing data of existing content but can\'t find a good ex

Answer 1

I had to edit this a bit to get it working in Django 1.11 with django-formtools 2.1.

class ProjectWizard(SessionWizardView):
    def get_form_initial(self, step):
        if 'project_id' in self.kwargs:
            return {}
        return self.initial_dict.get(step, {})

    def get_form_instance(self, step):
        if not self.instance_dict:
            if 'project_id' in self.kwargs:
                project_id = self.kwargs['project_id']
                return Project.objects.get(id=project_id)
        return None

The get_form_instance method now expects either an object or None to be returned.
