使用mongoengine登录django站点时出现错误配置错误

Question

我使用mongoengine将Django与MongoDB结合使用。我正在关注https://docs.djangoproject.com/en/1.7/intro/tutorial02/上的教程，因此想创建一个超级用户并登录。创建工作毫无问题。但是，当我尝试登录时，我受到以下网站的欢迎：

我想这与我使用settings.py中的虚拟数据库初始化数据库有关。但是有人告诉我，使用mongoengine需要这样做，并且它不会导致问题。无论如何：这是我的settings.py

的内容

Answer 1

请在setting.py文件中配置以下设置

import mongoengine
DATABASES = {
    'default': {
        'ENGINE': '',
    },
}

SESSION_ENGINE = 'mongoengine.django.sessions' # optional

_MONGODB_USER = 'mongouser'
_MONGODB_PASSWD = 'password'
_MONGODB_HOST = 'thehost'
_MONGODB_NAME = 'thedb'
_MONGODB_DATABASE_HOST = \
    'mongodb://%s:%s@%s/%s' \
    % (_MONGODB_USER, _MONGODB_PASSWD, _MONGODB_HOST, _MONGODB_NAME)

mongoengine.connect(_MONGODB_NAME, host=_MONGODB_DATABASE_HOST)

AUTHENTICATION_BACKENDS = (
'mongoengine.django.auth.MongoEngineBackend',
)

我希望上述解决方案可以解决您的问题。

Answer 2

what to do if database-engine not needed

  

默认数据库由某些默认身份验证API使用   用于Middleware-Apps。

尝试按如下方式制作MIDDLEWARE_APPS元组：

MIDDLEWARE_CLASSES = (
  'django.contrib.sessions.middleware.SessionMiddleware',
  'django.middleware.common.CommonMiddleware',
  'django.middleware.csrf.CsrfViewMiddleware',
  # 'django.contrib.auth.middleware.AuthenticationMiddleware',
  # 'django.contrib.auth.middleware.SessionAuthenticationMiddleware',
  'django.contrib.messages.middleware.MessageMiddleware',
  'django.middleware.clickjacking.XFrameOptionsMiddleware',
)

我只是一个初学者，所以如果有任何更多错误，请发表评论。

此解决方案打破了Django提供的默认管理面板后端。我正试图找到同样的工作。

  

在urls.py中重定向到管理页面的其他视图可能会有所帮助   虽然
