如何修复这些错误？

Question

我有一个 sqlite3 数据库 django 应用程序。我试图使用 djongo 切换到 MongoDB Atlas。但我不知道如何修复这些错误

我安装了 djongo

DATABASES = {
    'default': {
        'ENGINE': 'djongo',
        'NAME': 'test',
        'HOST': 'mongodb+srv://<username>:<password>@cluster0-bs91f.mongodb.net/test?ssl=true&ssl_cert_reqs=CERT_NONE&retryWrites=true&w=majority',
        'USERNAME': '<username>',
        'PASSWORD': '<password>',
    }
}

这是我在 settings.py 中唯一改变的地方

我不断收到这些错误。我不知道如何解决它们

Answer 1

您需要使用 urllib.parse 包解析您的密码（可能还需要登录）才能与 Pymongo 连接：

'password': urllib.parse.quote_plus("<password>")

Answer 2

如果您在密码中使用特殊字符，则会出现错误。请使用parse 或更改您的密码
