Question

我在炼油厂扩展中遇到STI错误。我有两个扩展名：“reservation_items”和“items” 现在我需要表“items”继承“reservation_items”。我用炼油厂生成器

生成了两个扩展


rails generate refinery:engine reservation_item date_from:date date_to:date people_min:integer people_max:integer price_1:float price_2:float price_3:float type:string --skip-frontend
rails g refinery:engine item item_type:integer

我在预订_items扩展程序中的模型：


module Refinery
  module ReservationItems
    class ReservationItem extends Refinery::Core::BaseModel
      self.abstract_class = true
      self.table_name = 'refinery_reservation_items'

      attr_accessible :date_from, :date_to, :people_min, :people_max, :price_1, :price_2, :price_3, :type, :position

      validates :type, :presence => true, :uniqueness => true
    end
  end
end

我将“items”扩展模型更改为：


module Refinery
  module Items
    class Item extends Refinery::ReservationItems::ReservationItem

      self.table_name = 'refinery_items'

      attr_accessible :item_type, :position

      # def title was created automatically because you didn't specify a string field
      # when you ran the refinery:engine generator. Refinery CMS.
      def title
        "Override def title in vendor/extensions/items/app/models/refinery/items/item.rb"
      end
    end
  end
end

我也试过了：


module Refinery
  module Items
    class Item extends ReservationItem

我不知道自己的坏事。我如何继承这两个表？

//请为“＆lt;”替换单词“extends”在代码中。

已解决：类“Item”不能包含“self.table_name”！
