django - pymongo.errors.OperationFailure : Authentication failed

Question

我正在尝试在 Django 中使用 MongoDB 数据库。为此，我将我的设置更改为此，我在这里使用 mlab。

settings.py

DATABASES = {
    'default': {
        'ENGINE': 'djongo',
        'NAME': 'crud-django',
        'HOST': 'mongodb://adityakmr:password1@ds231956.mlab.com:31956/',
        'USER': 'adityakmr',
        'PASSWORD': 'password1'
    }
}

但每次我尝试运行迁移时，我都会遇到这样的错误。我不知道它来自哪里我已经提供了正确的用户名和密码。我还使用 pip 安装了 djongo。

在最新版本中使用客户端连接到数据库。我希望以下数据库配置能够解决您的问题。

DATABASES = {
    'default': {
        'ENGINE': 'djongo',
        'ENFORCE_SCHEMA': True,
        'LOGGING': {
            'version': 1,
            'loggers': {
                'djongo': {
                    'level': 'DEBUG',
                    'propogate': False,                        
                }
            },
         },
        'NAME': 'my_db',
        'CLIENT': {
            'host': '127.0.0.1',
            'port': 27017,
            'username': 'XXXXXXXXXX',
            'password': "XXXXXXXXXXXXX",
            'authSource': 'admin',
            'authMechanism': 'SCRAM-SHA-1'
        }
    }
}
