Question

我试图在运行时将Django项目连接到MongoDB集群：

py manage.py runserver

或

py manange.py migrate

它一直显示相同的错误：

Watching for file changes with StatReloader

System check identified no issues (0 silenced).

pymongo.errors.OperationFailure: unsupported type in filter

我的setting.py配置为：

DATABASES = {
'default': {
    'ENGINE': 'djongo',
    'NAME': 'database_django',
    'HOST': 'mongodb+srv://xxxxxx:aaaaaa@isssgeneral-sfm0v.mongodb.net/test?retryWrites=true&w=majority',
    'PORT': 27017,
    'USERNAME': 'xxxxxx',
    'PASSWORD': 'aaaaaa' 
}
}

我的python环境如下：

pymongo            3.7.0
Django             2.2.2 
djongo             1.2.32
sqlparse           0.2.4
dnspython          1.16.0

我已经尝试过使用this post解决方案，该解决方案建议将pymongo降级到3.5.1版本，该版本已经尝试过但没有用。实际上，该项目以前在pymongo == 3.7版本中工作（我目前在环境中拥有该版本）。

我已经将此Django项目配置为连接到本地服务器，并且可以正常工作，显然主机名有些不适合。集群配置没有问题（我认为），因为我有一个直接连接到同一集群的Jupyter Notebook。

真的不知道我的项目发生了什么，突然停止了与我的Mongodb集群的连接。谁能帮助我找到解决该问题的方法？

谢谢社区。
