'WSGIRequest'对象在Google App Engine中没有属性'user'

Question

我是django和Google App Engine的新手，并且在使用数据存储时遇到问题。每次我做一个查询，如

db.GqlQuery("SELECT * FROM Listing ORDER BY date DESC LIMIT 10") 

我收到的错误：

'WSGIRequest' object has no attribute 'user' 

这个错误似乎Django的核心内context_processors.py产生。现在，我在互联网上发现的建议表示要评论用户相关的INSTALLED_APPS和MIDDLEWARE_CLASSES，但这似乎没有帮助。我的代码如下所示：

MIDDLEWARE_CLASSES = (
# 'django.middleware.common.CommonMiddleware', 
# 'django.contrib.sessions.middleware.SessionMiddleware', 
# 'django.contrib.auth.middleware.AuthenticationMiddleware', 
# 'django.middleware.doc.XViewMiddleware', 
) 

INSTALLED_APPS = (
# 'django.contrib.auth', 
    'django.contrib.contenttypes', 
# 'django.contrib.sessions', 
    'django.contrib.sites', 
) 

我的清单对象定义为以下（它有一个author属性较早，但这种情况正在注释掉和对象用新名称重新定义）：

class Listing(db.Model): 
    #author = db.UserProperty() 
    address = db.StringProperty() 
    date = db.DateTimeProperty(auto_now_add=True) 
    coords = db.GeoPtProperty() 

有谁知道是什么原因导致这个错误，以及如何解决它？这可能是不得不重置设置的情况吗？

UPDATE

通过sdolan提出的解决方案似乎是以下内容添加到应用程序的settings.py：

TEMPLATE_CONTEXT_PROCESSORS =（ “django.core.context_processors.debug”， “django.core.context_processors.i18n”）

这有效地除去第三默认处理器，django.core.context_processors.auth（其不应该存在是因为AppEngine我们不需要Django的auth组件）。

谢谢sdolan的解决方案！希望别人也可以使用它。 :)

@Nick，我认为这是值得把这个约CONTEXT_PROCESSORS金片教程（http://code.google.com/appengine/articles/django.html）

（原后续的问题）

有同样的问题，寻找为解决方案....所有当settings.py包含

DEBUG工作正常=真

但这个错误弹出（和杀死我的动机与学习进行）当我切换到

DEBUG =假
