尝试创建新客户端时,Mongoid无法找到名称的客户端配置:'default'

Question

我添加了生产数据库如下:

production:
  sessions:
    default:
      uri: <%= ENV['MONGOHQ_URL'] %>
      options:
        consistency: :strong
        max_retries: 1
        retry_interval: 0

取决于以下文档.

我MONGOHQ_URL通过以下命令创建:

heroku config:add MONGOHQ_URL=mongodb://user:pass@server.mongohq.com:port/db_name

但当我打开控制台时heroku run rails c.我得到以下内容:

There is a configuration error with the current mongoid.yml.

message:
  No clients configuration provided.
summary:
  Mongoid's configuration requires that you provide details about each client that can be connected to, and requires in the clients config at least 1 default client to exist.
resolution:
  Double check your mongoid.yml to make sure that you have a top-level clients key with at least 1 default client configuration for it. You can regenerate a new mongoid.yml for assistance via `rails g mongoid:config`.

 Example:
   development:
     clients:
       default:
         database: mongoid_dev
         hosts:
           - localhost:27017

Loading production environment (Rails 4.2.4) 

如何在mongoid.yml文件中添加生产配置以使用heroku进行部署？

他们更新了Mongoid 5中mongoid.yml文件的格式.而不是sessions它需要clients.还有其他一些变化,我知道user并且password现在嵌套在不同于之前的选项中.有关详细信息,请参阅Mongoid文档.

production:
  clients:
    default:
      ...
