Python的Unicode

Question

我有以下内容：

from django.db import models

class Category(models.Model):
    name = models.CharField(max_length=200)

    def _unicode_(self):
        return self.name

class Item(models.Model):
    category = models.ForeignKey(Category)
    dateadded = models.DateTimeField('date added')
    name = models.CharField(max_length=200)
    description = models.TextField()
    quantity = models.IntegerField()

我的问题是def _unicode_(self)不起作用。有什么想法吗？在
