Question

使用这样的模型设计：

class School(models.Model):
    name = models.CharField(max_length=50)

class Grade(models.Model):
    name = models.CharField(max_length=10)
    school = models.ForeignKey(School)

class Student(models.Model):
    name = models.CharField(max_length=100)
    grade = models.ForeignKey(Grade)

由于Student对象与School对象有直接关系，如何过滤django-admin以仅显示所选school的学生？

Answer 1

易

school_name = "your school name"
Students_in_school = Student.objects.filter(grade__school__name = school_name)
