ruby-on-rails - 如何在 ActiveScaffold Rails 3 中实现搜索

Question

我在 activescaffold 列表页面中的正常搜索不起作用。

我有 ListLocations 表，其中有字段 id | list_id | wiki_location_id。
我有以下模型关系

       class List < ActiveRecord::Base
         validates_presence_of :name
         has_many :list_locations, :dependent => :destroy
       end


       class WikiLocation < ActiveRecord::Base
         has_many :list_locations, :dependent => :destroy
       end

       class ListLocation < ActiveRecord::Base
         belongs_to :list
         belongs_to :wiki_location

         def wiki_location_title
           WikiLocation.find(wiki_location_id).title if wiki_location_id
         end

         def wiki_location_title= (title)
           wiki_location = WikiLocation.find_by_title(title)
           self.wiki_location_id = wiki_location.id if wiki_location
         end
       end

我的 Controller 是

      class Admin::ListsController < Admin::AdminController
        active_scaffold :list do |conf|
          conf.columns = [:name, :list_order, :enabled]
          conf.columns[:enabled].form_ui = :checkbox 
          conf.columns[:enabled].inplace_edit = true
          list.sorting = {:list_order => 'asc'}
        end
      end


      class Admin::WikiLocationsController < Admin::AdminController
        active_scaffold :wiki_location do |conf|
          conf.columns = [:title, :street]
          list.per_page = 10
        end
      end 


     class Admin::ListLocationsController < Admin::AdminController  
       active_scaffold :list_location do |conf|
         conf.columns = [:list, :wiki_location]
         conf.columns[:list].form_ui = :select
         conf.search.columns << :list
       end
     end

我还为 List_Locations 表中的 wiki_location 字段实现了 Search as you type(SAYT) 功能

我的观点看起来像





我已经按照以下指定链接 Activescaffold autocomplete 中的说明实现了自动完成功能

现在我的问题是当我在事件脚手架的列表页面中使用正常搜索时，我没有得到任何结果

我从控制台得到的查询是

 SELECT `list_locations`.`id` AS t0_r0, `list_locations`.`list_id` AS t0_r1, 
 `list_locations`.`wiki_location_id` AS t0_r2, `list_locations`.`created_at` AS t0_r3,
 `list_locations`.`updated_at` AS t0_r4, `lists`.`id` AS t1_r0, `lists`.`name` AS t1_r1,
 `lists`.`list_order` AS t1_r2, `lists`.`enabled` AS t1_r3, `lists`.`created_at` AS 
  t1_r4, `lists`.`updated_at` AS t1_r5 FROM `list_locations` LEFT OUTER JOIN `lists` ON 
 `lists`.`id` = `list_locations`.`list_id` WHERE ((((`lists`.`id` LIKE '%museum%'))))
  ORDER BY `list_locations`.`id` ASC LIMIT 15 OFFSET 0

它看起来像是在 lists.id 字段而不是 list.name 上搜索

为什么会这样。我怎样才能让它搜索list.name。我还需要搜索 wiki_locations.title 列。如何才能做到这一点。请帮忙。

尝试设置:

conf.columns[:list].search_sql = 'list.name'
