使用OneToOne关系访问Django中的模型

Question

我有以下模型，这些模型取决于django.contrib.auth.models.User。

from django.db import models
from django.contrib.auth.models import User

class Teacher(models.Model):
    user = models.OneToOneField(User, related_name='teacher')
    ...

class Student(models.Model):
    user = models.OneToOneField(User, related_name='student')
    ...

如何获得与QuerySet相关的User Teacher个对象？

Answer 1

User.objects.exclude(teacher=None)
