Question

我收到 TypeError：强制转换为Unicode：需要字符串或缓冲区，找到int

这是我的models.py：

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

    def __unicode__(self):
            return self.person

当我在我的视图中检索 FollowingModel 中的值时

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)

但没有用，我仍然得到同样的错误。有谁能指导我？

谢谢！

更新

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

u = unicode(self)
TypeError: coercing to Unicode: need string or buffer, int found

Answer 1

__unicode__ method should return just that, unicode：

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