Django管理外键下拉字段列表只有"测试对象"

Question

我有这两个类:

class Test(models.Model):
    id = models.AutoField(primary_key=True)
    user = models.ForeignKey(User)
    groups = models.ManyToManyField(Group)

class TestSubjectSet(models.Model):
    id =  models.AutoField(primary_key=True)
    test = models.ForeignKey(Test)
    subject = models.ManyToManyField(Subject)

TestSubjectSet表单测试列表仅显示字符串"test object".

Answer 1

您必须在模型类中添加__unicode__(self)或__str__(self)方法.

Answer 2

有同样的问题。添加

def __str__(self):
    return self.user

解决了这个问题。
