当试图创建新的客户端，Mongoid找不到名称的客户端配置：“默认”

Question

我补充生产数据库，如下所示：

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

取决于以下docs。

我用以下命令创建MONGOHQ_URL：

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

但是当我通过heroku run rails c打开控制台。我有以下几点：

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) 

我怎样才能在mongoid.yml文件中添加生产配置中使用Heroku的部署？

Answer 1

他们更新了Mongoid 5中mongoid.yml文件的格式。而不是sessions它需要是clients。还有一些其他的变化，我知道user和password现在嵌套在选项之下不像以前。有关详细信息，请参阅Mongoid docs。

production: 
    clients: 
    default: 
     ...
