Question

class BasicInfo(models.Model):
  username = models.OneToOneField(User, on_delete=models.CASCADE)
  email = models.EmailField(max_length=250)
  abstratct=True

class Student(Basicinfo):
   #Student class definition

当我查询时：

user=user.objects.get(user="name")
student=Student.objects.get(username=user)

但是：

user.student_set.all() gives error

'用户'对象没有属性'student_set'??

Answer 1

只需将related_name添加到学生模型即可访问： https://docs.djangoproject.com/en/1.11/ref/models/fields/#django.db.models.ForeignKey.related_name

“用户”对象没有属性“student_set”
