django - django.core.exceptions.ImproperlyConfigured: name は basestring のインスタンスでなければなりません

Question

で使用しようとMongodbしていDjangoます。

以下に接続設定がありますsettings.py

DEBUG = True
TEMPLATE_DEBUG = DEBUG

ADMINS = (
    # ('Your Name', 'your_email@example.com'),
)


MANAGERS = ADMINS



DATABASES = {
    'default': {
        'ENGINE': 'django_mongodb_engine', 
        'NAME': '',                      
        'USER': '',                      
        'PASSWORD': '',                  
        'HOST': 'localhost',                      
        'PORT': 27017,                      
    }
}

実行しようとするとpython manage.py syncdb、次のようなエラーが発生します。

django.core.exceptions.ImproperlyConfigured: name must be an instance of basestring

私はジャンゴ1.3を使用しています

前もって感謝します
