You can try below code to get exact thing you want

>>> from django.db.models import Min

(u'First1', 10)

If you pass the Min as positional argument, then the field's name is price__min. Otherwise, if you pass it as keyword argument, i.e. aggregate(my_min=Min('price')), then it will be available with the same name as the argument, in this case my_min. Docs
