You want the values() queryset call (http://docs.djangoproject.com/en/dev/ref/models/querysets/#values-fields ). Your query would probably look like User.objects.values('first_name'), or if you wanted a plain list (values usually returns a dictionary), you can use values_list() with the 'flat' parameter.
