NameError: name 'QuerySet' is not defined

Question

I'm getting the NameError: name 'QuerySet' is not defined error in below line.

QuerySet(query=MappingTraineeQ.objects.filter(date__range=(startdate,enddate)).query, model=MappingTraineeQ)

I'm not getting the problem, do I need to import anything for this? or I missed something.

please help me with the above.

Thanks

What are you trying to do? It looks like an import problem, but I have never seen querysets used like that. — wobbily_col, Jun 14 '17 at 11:19
I'm trying to implement group by using querysets. ref: https://stackoverflow.com/a/629600/5180613 — piyush singh, Jun 14 '17 at 11:21
@DanielRoseman yes, it's not working. I was trying but not succeed yet. I was following this https://stackoverflow.com/questions/629551/how-to-query-as-group-by-in-django/629600#629600. — piyush singh, Jun 14 '17 at 12:07

You could import Queryset like,

from django.db.models.query import QuerySet
