Python Mongo+；博士后&x2B；Django测试错误-多个数据库（Django MongoDB引擎）

我一直在尝试让我的django测试为我正在构建的API工作。我是Python新手，已经在这方面停留了一段时间

一些快速的事实：

• 我正在使用两个数据库——一个用于我的用户的postgresql数据库和一个用于其他一切的mongo数据库
• 我使用的是TastyPie、Django MongoDB引擎、Django工具箱、Django Non-rel、Pymongo和psycopg2
• 我已成功连接到数据库。当我从shell中保存auth_用户时，它将保存到sql数据库，并将模型从我的应用程序保存到mongoDB

我必须将其与另一个API集成，因此仅限于数据库和库的选项

我最大的问题是测试-我无法让它工作。

当我尝试使用./manage.py test运行Django的测试时，我不断遇到以下错误：

pymongo.errors.OperationFailure: command SON([('authenticate', 1), ('user', u'test'), ('nonce', u'blahblah'), ('key', u'blahblah')]) failed: auth fails

经过广泛的搜索，我仍然不知道它是什么。我知道很明显有什么东西试图通过我的MongoDB进行身份验证，但它不允许这样做。我不介意使用这个数据库进行测试，因为它是一个测试数据库

请帮忙！下面是我的配置和错误消息

感谢您的帮助

想更新一下我是如何解决这个问题的-我认为这是一个读/写问题（auth失败的问题），但事实并非如此

如果您看到此错误，则是身份验证问题-您的用户名、密码、数据库名称或集合名称不正确

pymongo.errors.OperationFailure: command SON([('authenticate', 1), ('user', u'test'), ('nonce', 
u'blahblah'), ('key', u'blahblah')]) failed: auth fails

Django在设置测试数据库时，会在数据库名称的开头添加“test”。因此，我的主数据库maindb被创建为“test_maindb”

您可以在以下位置查看有关此的信息：

确保您可以写入一个单独的数据库，该数据库名为您的数据库名，并在名称后面附加“test”

另外-另一种解决方案是在数据库设置中定义测试数据库设置。这可以通过在任何数据库属性中附加“TEST_3;”来完成。例如：

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'maindb',
        'USER': os.environ['RDS_USERNAME'],
        'PASSWORD': os.environ['RDS_PASSWORD'],
        'HOST': os.environ['RDS_HOSTNAME'],
        'PORT': os.environ['RDS_PORT'],
        'TEST_NAME': 'my_test_sql',
        'TEST_USER': 'test_sql_user',
        'TEST_PASSWORD': 'password'
    },
    'mongo': {
        'ENGINE': 'django_mongodb_engine',
        'NAME': 'mongodb',
        'USER': os.environ['MONGO_USERNAME'],
        'PASSWORD': os.environ['MONGO_PASSWORD'],
        'HOST': os.environ['MONGO_HOSTNAME'],
        'PORT': os.environ['MONGO_PORT'],
        'TEST_NAME': 'my_test_mongodb',
        'TEST_USER': 'test_mongo_user',
        'TEST_PASSWORD': 'password'
    }
}
