[Answer]-Django queryset filter model attribute against other model attribute

I’m not sure if it will work in this case, but generally you can use F() objects for this.

from django.db.models import F
qs = InstanceItemEvaluation.objects.filter(
    user=user, 
    instance=instance, 
    factor__is_active=True, 
    measure__is_active=True).exclude(
    factor__measure=None).filter(
    factor__measure=F('measure_id'))
