Ruby 如何在Roda中划分嵌套管线

我使用Roda编写了一个应用程序。 我有一个这样的嵌套路由器：

   route 'chats' do |r|
      env['warden'].authenticate!
      r.is do
        @current_user = env['warden'].user

        r.get do
          # code is here
        end

        r.post do
          # code is here
        end
      end

      r.on :String do |chat_id|
        r.is 'messages' do
          # code is here

          r.get do
            # code is here
          end

          r.post do
            # code is here
          end
        end
      end
    end

route 'chats' do |r|
  # code is here
end
route 'chats/:chat_id/messages' do |r, chat_id|
  # code is here
end

我想将一个大代码块分成两条路径，如下所示：

   route 'chats' do |r|
      env['warden'].authenticate!
      r.is do
        @current_user = env['warden'].user

        r.get do
          # code is here
        end

        r.post do
          # code is here
        end
      end

      r.on :String do |chat_id|
        r.is 'messages' do
          # code is here

          r.get do
            # code is here
          end

          r.post do
            # code is here
          end
        end
      end
    end

route 'chats' do |r|
  # code is here
end
route 'chats/:chat_id/messages' do |r, chat_id|
  # code is here
end

请帮忙。如何正确操作？

您需要启用两个插件：

• -允许在单独的文件之间拆分路由
• -沿路线传递变量

然后，在最高级别声明路由，如下所示：

  # routes/root.rb
  class YourApp::Web
    route do |r|
      r.on('chats') do
        r.is do
          r.route 'chats'
        end

        r.is(String, 'messages') do |chat_id|
          shared[:chat_id] = chat_id
          r.route 'chats_messages'
        end
      end
    end
  end

之后，您可以将聊天和聊天信息放入单独的文件中：

  # routes/chats.rb
  class YourApp::Web
    route ('chats') do |r|
      r.get do
        # ....
      end

      r.post do
        # ....
      end
    end
  end

  # routes/chats_messages.rb
  class YourApp::Web
    route ('chats_messages') do |r|
      chat_id = shared[:chat_id]
      r.get do  
        # ....
      end

      r.post do  
        # ....
      end
    end
  end
