How can i get the model name for empty queryset?
EDIT:

回答1:
>>> students = Students.objects.all()
# The queryset's model class:
>>> students.model
project.app.models.Student
# Name of the model class:
>>> students.model.__name__
'Student'
# Import path of the models module:
>>> students.model.__module__
'project.app.models'
# Django app name:
>>> students.model._meta.app_label
'app'

students.model
Querysets have a model attribute that can be used to retrieve the model they are associated with.

You can do:
