Fix object has no attribute 'object_list' when post create duplicate in Django-Tables2 ListView

views.py

class mylist(SingleTableMixin, FilterView):
  ...
  
  def get_context_data(self, **kwargs):
        queryset = kwargs.pop('object_list', None)
        if queryset is None:
            self.object_list = self.model.objects.all()
        ...
        return super().get_context_data(**kwargs)
          
  def post(self, request, *args, **kwargs):
        form = self.get_form()
        if form.is_valid():
            instance = form.save(commit=False)
            ...
            instance.save()

            return self.form_valid(form)
        else:

            return self.form_invalid(form)

This saved a lot of headaches. Thanks

Yes, it's solved... Thank you! 🙏

I've got the same issue no object_list appears on ListView.
I tried the above code, and I expected, there would be duplicates, as I am working on both: Django.views.generic.base import TemplateView, and: Django.views.generic.list import ListVies. the problem is not resolved! unfortunetaly
