Searchkick多模型查询

Question

我正在尝试运行一个查询来查找给定位置中的所有项目。我有一个Item.rb & Location.rb模型，其中有searchkick。在我的items控制器中，我有以下逻辑：

if params[:item_name].present?
    @items = Item.search(params[:query], index_name: [Item.searchkick_index.item_name, Location.searchkick_index.city])

(:item_name用于捕获参数)

Ant日志如下：

Parameters: {"utf8"=>"✓", "item_name"=>"test", "city"=>"Memphis", "commit"=>"Search"}
  User Load (0.2ms)  SELECT  "users".* FROM "users" WHERE "users"."id" = ? LIMIT 1  [["id", 12]]
  CACHE (0.0ms)  SELECT  "users".* FROM "users" WHERE "users"."id" = ? LIMIT 1  [["id", 12]]
Completed 500 Internal Server Error in 3ms

NoMethodError (undefined method `item_name' for #<Searchkick::Index:0x007fb43858d4e8>):
app/controllers/items_controller.rb:9:in `index'

我已经尝试重新索引位置和项目，重新启动服务器，但都没有用。

如何在两个/n模型上构建搜索？

Answer 1

我认为您只需要指定索引的名称，例如

if params[:item_name].present?
    @items = Item.search(params[:query], index_name: [Item.searchkick_index.name, Location.searchkick_index.name])

然后，Searchkick将在您在SearchKick配置中为这些模型定义的任何字段中搜索项目和位置模型。
