Ruby on rails 关于将Mongoid Gem更新为版本5的警告问题

我已经将mongoid gem从mongoid-4 on rails 4应用程序更新为5。我在应用程序重启时面临以下警告

W, [2017-02-15T13:59:49.356541 #14483]  WARN -- : MONGODB Unsupported client option 'max_retries'. It will be ignored.

W, [2017-02-15T13:59:49.356739 #14483]  WARN -- : MONGODB 
Unsupported client option 'retry_interval'. It will be ignored.

如何更新Mongoid Yml以删除警告

这也是当前的YML文件

staging:
    clients:
      default:
         database: chillr_api
         hosts:
            - localhost:27017
      options:
        read:
          mode: :nearest
    # In the test environment we lower the retries and retry interval to
    # low amounts for fast failures.
          max_retries: 1
          retry_interval: 0
          username: 'username'
          password: 'username'

好的。看来最大重试次数和重试间隔是Moped配置。由于Mogoid 5中删除了轻便摩托车，因此可以将其从配置中删除。Yml示例

只需删除该选项？不，我想知道如何在Mogoid 5中启用该选项。我想。最大重试次数：1和重试间隔是Moped配置，在mongoid 5中删除
