Question

我可以使用由某些硬件收集的数据访问巨型MongoDB数据库。当前在远程服务器上。我需要使用Django进行开发（最好）。

我可以使用直接的pymongo很好地进行迭代，但是我想使用Django的内置功能来做更多的事情。我绝对喜欢Django处理数据的方式，而不是运行mongodb查询。所以我安装了Djongo-Django的连接器。

有了Pymongo，我就这样使用它

client = MongoClient('ipaddress',
                     username='ronald',
                     password='password',
                     authSource='scanning',
                     authMechanism='SCRAM-SHA-1')

db = client["scanning"]

collection = db["some_collection"]

这很好，我可以毫无问题地连接到收藏夹。

所以继续前进到Djongo，我想我也可以类似地连接到它，但是，我一直在超时。这是我在Settings.py

中的数据库设置

DATABASES = {
    'default': {
        'ENGINE': 'djongo',
        'ENFORCE_SCHEMA': False,
        'NAME': 'some_collection',
        'HOST': 'ipaddress',
        'PORT': 27017,
        'USER': 'ronald',
        'PASSWORD': 'password',
        'AUTH_SOURCE': 'scanning',
        'AUTH_MECHANISM': 'SCRAM-SHA-1',
    }
}

这会在启动服务器时不断超时。

是否有可能这样做？

我是否最好将数据库转储到本地并将其存储在针对Django优化的干净的MongoDB中？

我应该只接受品尝，只运行mongo查询吗？

任何建议将不胜感激。

谢谢
