Question

我是django和Google App Engine的新手，我在使用数据存储时遇到了麻烦。每次我进行查询，例如

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

我收到错误：

'WSGIRequest' object has no attribute 'user'

这个错误似乎是在django核心的context_processors.py中生成的。现在，我在互联网上发现的建议是评论用户相关的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',
)

我的列表对象定义如下（它之前有一个作者属性，但现在已注释掉，并且使用新名称重新定义了对象）：

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

有谁知道导致此错误的原因，以及如何解决？是否可能需要以某种方式重置设置？

<强>更新

sdolan建议的解决方案似乎是将以下内容添加到app的settings.py中：

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

这有效删除第三个默认处理器django.core.context_processors.auth（不应该存在，因为对于AppEngine我们不需要Django的auth组件）。

谢谢你，sdolan，解决方案！希望其他人也可以使用它。：）

@Nick ，我认为值得在教程中提出关于CONTEXT_PROCESSORS的这篇黄金文章（http://code.google.com/appengine/articles/django.html）

（问题的原始跟进）

遇到同样的问题，寻找解决方案....当settings.py包含

时，一切正常

DEBUG = True

但是当我切换到

时，会弹出这个错误（并且会影响我继续学习的动力）

DEBUG = False

“WSGIRequest”对象在Google App Engine中没有“用户”属性
