'WSGIRequest'對象在Google App Engine中沒有屬性'user'

Question

我是django和Google App Engine的新手，並且在使用數據存儲時遇到問題。每次我做一個查詢，如

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

我收到的錯誤：

'WSGIRequest' object has no attribute 'user' 

這個錯誤似乎Django的核心內context_processors.py產生。現在，我在互聯網上發現的建議表示要評論用戶相關的INSTALLED_APPS和MIDDLEWARE_CLASSES，但這似乎沒有幫助。我的代碼如下所示：

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', 
) 

我的清單對象定義爲以下（它有一個author屬性較早，但這種情況正在註釋掉和對象用新名稱重新定義）：

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

有誰知道是什麼原因導致這個錯誤，以及如何解決它？這可能是不得不重置設置的情況嗎？

UPDATE

通過sdolan提出的解決方案似乎是以下內容添加到應用程序的settings.py：

TEMPLATE_CONTEXT_PROCESSORS =（ 「django.core.context_processors.debug」， 「django.core.context_processors.i18n」）

這有效地除去第三默認處理器，django.core.context_processors.auth（其不應該存在是因爲AppEngine我們不需要Django的auth組件）。

謝謝sdolan的解決方案！希望別人也可以使用它。 :)

@Nick，我認爲這是值得把這個約CONTEXT_PROCESSORS金片教程（http://code.google.com/appengine/articles/django.html）

（原後續的問題）

有同樣的問題，尋找爲解決方案....所有當settings.py包含

DEBUG工作正常=真

但這個錯誤彈出（和殺死我的動機與學習進行）當我切換到

DEBUG =假

@Nick約翰遜，這裏的堆棧跟蹤：
