python - django - 类型错误 : coercing to Unicode

Question

我收到TypeError: coercing to Unicode: need string or buffer, int found

这是我的模型.py:

class FollowingModel(models.Model):
    user = models.ForeignKey(User)
    person = models.IntegerField(max_length=20, blank=False)

    def __unicode__(self):
            return self.person

当我像这样在我的 View 中检索 FollowingModel 的值时

g = FollowingModel.objects.all()
g[0] -----> I'm getting that error

我尝试将 def __unicode__(self): 更改为

def __unicode__(self):
    return str(self.person)

但是没有用，我仍然得到同样的错误。谁能指导我？

谢谢!

更新

>>>g = FollowingModel.objects.all()
>>>g

u = unicode(self)

Answer 1

__unicode__ method should return just that, unicode :

def __unicode__(self):
    return unicode(self.person)
