Python model列相等查找django需要怎么处理，pythondjango,数据表中有2个字段都指向

数据表中有2个字段都指向一个外键

class Student(models.Model):  old_school = model.ForeignField(School)  school = model.ForeignField(School)

我想找出所有old_school == school的行，请问这个怎么处理？
我试过了用：

Student.objects.all().exclude(old_school = school)Student.objects.all().exclude(old_school__id = school__id)Student.objects.all().exclude(old_school = self.school)

都不行。

from django.db.models import FStudent.objects.filter(old_school=F(“school”))
