在ActiveAdmin中自定义“查看”动作

Question

我是新来的红宝石在轨道上和红宝石轨道上使用第4版工作的项目。现在我正在改变活动管理员中的订单视图，但我收到错误。

ActiveAdmin.register Order do 
    permit_params :id, :order_completed, :approved 

    # changing the visual of view action, so admin user can able to see complete order details 
    show do |order| 
     attributes_table do 
      row :id # Order ID 
      row 'Name' params[:user].first_name # its not working, not showing the user first_name assiated with order id 
      # It should be user name. although user first_name is in users table and User model is availble. 
      row 'Adress' params[:user].address # its not working, not showing the user address assiated with order id 
      # It should be user address. although user first_name is in users table and User model is availble. 
     end 
    end 

    controller do 
     def show 
      order_id = Order.find(params[:id]).user_id 
      params[:user] = User.find(order_id) 
      show! 
     end 
    end 
end 

我的目标是显示订单相关联的用户的详细信息，如地址，名称等

Order表由

- id 
- user_id 
- order_completed (boolean) 
- approved 
- order_status (string) [in process, done] 

用户表组成的

- id 
- first_name 
- last_name 
- address 
- membership_id

我会假设你已经在他们各自的模型中建立了类“订单”和类“用户”之间的关系。 （belongs_to的和的has_many方法如果您需要更多这方面的帮助，让我知道。） 然后你也必须申报Activeadmin这种关系，当你注册的类，所以试试这个：

app/admin/order.rb: 
    ActiveAdmin.register Order do 
     permit_params :id, :order_completed, :approved 
     belongs_to :user # Declaring that order belongs to user here 

     # changing the visual of view action, so admin user can able to see complete order details 
     show do |order| 
      attributes_table do 
       row :id # Order ID 
       row 'Name' do 
        @order.user.first_name 
       end 
       row 'Address' do 
        @order.user.address 
       end 
      end 
     end 

     controller do 
      def show 
       @order = Order.find(params[:id]) 
       show! 
      end 
     end 
    end`
