Chartjs-Django admin/ Chart js error – super() takes at least 1 argument (0 given)

The problem is that you use Python Version: 2.7.9 and author of your artical use Python 3.7.3

You can try use this for fix

return super(admin.ModelAdmin, self).changelist_view(request, extra_context=extra_context)

But i gues this is not the only place where you’ll get errors
