在Django中訪問與模型具有OneToOne關系的對象

Question

我有以下模型，這些模型取決於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')
    ...

如何獲得與Teacher相關的User對象的QuerySet ？

Answer 1

User.objects.exclude(teacher=None)
