I' m noob to Django and was trying to run the app. I simply downloaded the app and getting the following error.

Environment:

On line 315 of quiz/models.py:

Replace:

question_set = question_set.values_list('id', flat=True) with question_set = [item.id for item in question_set]

I think the issue is that model_utils changed and that question_set is different. I am not sure though, and this got it working for me.

I faced the mentioned error even with this change above, however, this issue is resolved by updating django-model-utils (tested on version 2.5.2) pip install django-model-utils==2.5.2
