Ruby 是否将activerecord上的访问器方法映射到activeresource上的属性?,ruby,ruby-on-rails-3,activerecord,model,activeresource,Ruby,Ruby On Rails 3,Activerecord,Model,Activeresource,ActiveModel中指定的一些属性是非db属性,它们只是定义为getter setter。问题是这些属性值并没有反映在客户端的activeresource记录上 #server side code class Item < ActiveRecord::Base #not null name attribute defined on db end class SpecialItem < ActiveRecord::Base

ActiveModel中指定的一些属性是非db属性,它们只是定义为getter setter。问题是这些属性值并没有反映在客户端的activeresource记录上

    #server side code
    class Item < ActiveRecord::Base
       #not null name attribute defined on db 
    end

   class SpecialItem < ActiveRecord::Base
      #nullable item_name attribute defined on db

      #association many to one for item defined here

      #name accessor 
      def name
         if !item_name.nil?
           return item_name
         else
           return item.name
         end 
      end  
   end

   #client side code
   class SpecialItem < ActiveResource::Base
        schema do
      attribute 'name', 'string'
        end
   end
#服务器端代码
类项
我在客户端上为SepcialItem记录的属性名获取nil值。基本上,我正在尝试将访问器方法名称映射到客户端的name属性

    #server side code
    class Item < ActiveRecord::Base
       #not null name attribute defined on db 
    end

   class SpecialItem < ActiveRecord::Base
      #nullable item_name attribute defined on db

      #association many to one for item defined here

      #name accessor 
      def name
         if !item_name.nil?
           return item_name
         else
           return item.name
         end 
      end  
   end

   #client side code
   class SpecialItem < ActiveResource::Base
        schema do
      attribute 'name', 'string'
        end
   end

什么是可能的解决方案?

ActiveResource是一种与RESTful服务通信的方法,需要定义类变量
site
,即

   class SpecialItem < ActiveResource::Base
     self.site = 'http://example.com/'
     self.schema = { 'name' => :string}
   end
class SpecialItem:string}
结束
这将利用默认的Rails集合和元素约定。因此,对于SpecialItem.find(1)的调用,ActiveResource将路由到
GEThttp://example.com/specialitems/1.json
