Ruby on rails 如何在mongoid.yml中的同一Rails环境中设置多个数据库（不同）连接？

（即，当在模型中明确定义时，一些模型将使用默认数据库，而其他模型将使用第二个数据库）

我找不到这方面的任何最新参考资料。 我想知道下面提到的类似事情是否可行

development:
  clients:
    default:
      uri: <%=ENV['DEFAULT_DB']%>
    mongo_db:
      uri: <%=ENV['SECOND_DB']%>

development:
  clients:
    default:
      uri: <%=ENV['DEFAULT_DB']%>
    mongo_db:
      uri: <%=ENV['SECOND_DB']%>

system_metric.rb

class GraphMetric
  include Mongoid::Document
  include Mongoid::Timestamps

  #Connects to default

  field :timestamp, type: DateTime

end

class SystemMetric
  include Mongoid::Document
  include Mongoid::Timestamps

  #Connect to mongo_db
   some method to establish_connection

  field :timestamp, type: DateTime

end

class GraphMetric
  include Mongoid::Document
  include Mongoid::Timestamps

  #Connects to default

  field :timestamp, type: DateTime

end

class SystemMetric
  include Mongoid::Document
  include Mongoid::Timestamps

  #Connect to mongo_db
   store_in client: :mongo_db

  field :timestamp, type: DateTime

end

store_in

client

会为您解决问题吗？
