Django属性错误

Question

我在Django项目中遇到了麻烦。 Python 2.7，apache 2.2，mysql数据库; 这是models.py

from django.db import models 
from django.contrib import admin 

class Item(models.Model): 
    name = models.CharField(max_length=150) 
    description = models.TextField() 

    class Meta: 
     ordering = ['name'] 

    def __unicode__(self): 
     return self.name 

    def get_absolute_url(self): 
     return 'item_detail', None, {'object_id': self.id} 


class Photo(models.Model): 
    item = models.ForeignKey('Item') 
    title = models.CharField(max_length=100) 
    image = models.ImageField(upload_to='photos') 
    caption = models.CharField(max_length=250, blank=True) 

    class Meta: 
     ordering = ['title'] 

    def __unicode__(self): 
     return self.title 

    def get_absolute_url(self): 
     return 'photo_detail', None, {'object_id': self.id} 


class PhotoInline(admin.StackedInline): 
    model = Photo 


class ItemAdmin(admin.ModelAdmin): 
    inlines = [PhotoInline] 


admin.site.register(Item, ItemAdmin) 
admin.site.register(Photo) 

的代码时，我尝试在管理面板创建对象的项目是给我一个错误

我刚刚在我的一个项目中试过了你的代码片段，它的工作方式就像一个魅力，我没有看到任何问题，你确定，你仍然得到这个错误。如果是这样，请检查您的数据库，并看到你有设置文件中的媒体设置python路径。
