Django Queryset for no-operation

Question

Is there any way to specify a Django Queryset, which will do nothing but still be valid Queryset? Empty queryset should ideally not call DB and results would be empty.

Answer 1

Use MyModel.objects.none() which will return an EmptyQuerySet, which is a QuerySet subclass that always evaluates to an empty list.

For eg., if you have a model class Entry (or just use models.Model), you can simply create an EmptyQuerySet by:

>>> Entry.objects.none()
[]

Answer 2

Model.objects.none()

always gives you an empty queryset
