connect(

，并更改settings.py

编辑我的代码，但仍然得到同样的错误数据库= {} 从mongoengine进口连接连接（ DB = '聚甲醛'，用户名= '根'，密码= '根'，主机=“localhost”的） –

主机需要给予像我给什么，用户/本地主机 – Exprator

我仍然得到同样的错误连接（ DB =“聚甲醛”，用户名=“管理员”，密码= 'root'， host ='mongodb：// admin：root @ localhost/po m' ） –

答

的DATABASES到DATABASES = {}节。如果你不想因为你使用mongoengine，而不是配置的数据库，然后删除DATABASES完全取决于您的设置，或将其更改为空字典。

DATABASES = {}

如果您在您的DATABASES字典的任何项目，那么他们必须包括ENGINE，否则你会得到ImproperlyConfigured错误。

DATABASES = { 
    'default': { 
     'ENGINE': 'django.db.backends.sqlite3', 
     ... 
    }, 
}

我得到同样的错误空字典DATABASES = {}。和第二个选项的问题是，我有mongodb作为数据库是有效的使用sqllite3引擎？ –

我认为它与引擎错误相关。其实我在这个项目中用mongodb数据库替换sql，所以首先我试图在django和mongodb数据库之间建立连接，但是它给了我这个错误 –

我[不确定mongoengine是否支持Django]（https：// github.com/MongoEngine/django-mongoengine），所以我无法帮助。我只能说你的原始问题中的'ENGINE'：''，'绝对无效。 – Alasdair

Django1.8和Mongoclient settings.DATABASES配置不正确。
