しかし、私はMongoDBの接続が正常であることを確認しますこの問題？ settings.py

DATABASES = { 
'default': { 
    'ENGINE': 'django.db.backends.dummy', 
} 
} 

_MONGODB_USER = 'marcin' 
_MONGODB_PASSWD = '1234' 
_MONGODB_HOST = 'localhost' 
_MONGODB_NAME = 'znaczki' 
_MONGODB_DATABASE_HOST = \ 
    'mongodb://%s:%s@%s/%s' \ 
    % (_MONGODB_USER, _MONGODB_PASSWD, _MONGODB_HOST, _MONGODB_NAME) 

mongoengine.connect(_MONGODB_NAME, host=_MONGODB_DATABASE_HOST) 

で

あなたsettings.pyファイルには、次のものが含まれている必要があります

import mongoengine 

# ... 

# DATABASES section should be: 
DATABASES = { 
    'default': { 
     'ENGINE': '', 
    }, 
} 

SESSION_ENGINE = 'mongoengine.django.sessions' 

_MONGODB_USER = 'db_user' 
_MONGODB_PASSWD = 'db_password' 
_MONGODB_HOST = 'db_host' 
_MONGODB_NAME = 'db_name' 
_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', 
) 

`あなた` settings.py`ファイルにDATABASES`セクションでどのように
