我无法在本地运行我的 Django 服务器。我正在尝试设置我的djongo数据库而不是默认的sqlite3 .db

在这里，我在 python设置上按照以下 djongo djongo 的 URL

在这里，我包含了我的 setting.py 供您参考。

DATABASES = {
  'default' : {
    'ENGINE' : 'djongo',
    'NAME' : 'my_database'
  }
}

INSTALLED_APPS = [
    'polls',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
]

连接数据库时是否包含了USERand ？PASSWORD由于错误是connection refused，您可能需要将凭据包含到您的数据库设置中，例如USER和PASSWORD。

例如，

DATABASES = {
    'default' : {
        'ENGINE' : 'djongo',
        'NAME' : 'my_database',
        'USER' : 'db-username',
        'PASSWORD': 'db-password'
    }
}

如果没有，可以参考下面的Pymongo一直拒绝连接在27017
