python - Django 无法连接到 mongoDB 地图集

问题描述

最近我开始了一个项目，使用 Django 后端和托管在其 Atlas 平台上的 mongoDB 数据库制作 Web 服务器，因此我不必担心在本地运行它。

我仍处于设置的早期阶段并遇到此错误：

pymongo.errors.ServerSelectionTimeoutError: localhost:27017: [WinError 10061] No connection could be made because the target machine actively refused it

可能还需要提及的是，我目前在数据库或模型上没有 Django 应用程序形式的文档，但我怀疑这是问题，因为当我运行时manage.py migrate我得到上述错误，而不是“没有带有标签的应用程序” “ 错误。

我的 settings.py 中的数据库配置当前如下所示：

DATABASES = {
    'default': {
        'ENGINE': 'djongo',
        'NAME': 'house-project',
        'HOST': 'mongodb+srv://<my-user-name>:<my-password>@house-project-9g5fo.gcp.mongodb.net/test?retryWrites=true&w=majority'
    }
}

我知道常见的错误之一是您的密码和用户名中有特殊字符，我已确保不包含任何字符或使用十六进制字符转义它们。我已确保在 Atlas 端添加我的 ip 和用户。我在网上查了一个现有的答案，但无济于事。我发现的最接近的问题是：如何将 Django ORM 连接到 mongo atlas？，但遗憾的是，这个解决方案对我不起作用。

在尝试解决此问题时，任何帮助都会非常有用，如果需要有关我的设置的任何其他信息，请告诉我，我很乐意提供。我还包括了一个堆栈跟踪，以防它在下面相关。

解决方案

Djongo 文档不正确或过时。我能够使用以下设置让我的 Django 应用程序连接到 mongodb：

DATABASES = {
    'default': {
        'ENGINE': 'djongo',
        'CLIENT': {
            'host': 'mongodb+srv://<URL>',
            'username': 'something',
            'password': 'somepass',
            'authMechanism': 'SCRAM-SHA-1'
        }
    }
}
