ruby-on-rails - Elasticsearch 和轮胎

Question

您好，我正在尝试在我的项目中使用tire和elasticsearch。

我能够索引模型并查询每个模型，但是我很难使用联接表。

我的模特

class Item < ActiveRecord::Base
attr_accessible :category_id, :description, :name, :rating
belongs_to :category
has_and_belongs_to_many :posts
include Tire::Model::Search
include Tire::Model::Callbacks
after_save do
  update_index
end

tire.mapping do
  indexes :name,  :analyzer => 'snowball', :boost => 100
  indexes :posts
end
end



class Post < ActiveRecord::Base
include Tire::Model::Search
include Tire::Model::Callbacks
has_and_belongs_to_many :tags
has_and_belongs_to_many :items


attr_accessible :posted_at, :text, :thread_id, :username

tire.mapping do
  indexes :id, type: 'integer'
  indexes :text, :analyzer => 'snowball', :boost => 100
  indexes :thread_id, type: 'integer'
  indexes :posted_at, type: 'date'
end
end

如您所见，我在Item和Post之间有一个联接表

如果我有商品名称，该如何通过 Elasticsearch 或Item.search(name).posts来搜索Post.search(属于该商品的帖子)？

可能最好的办法就是从这里开始:

然后看http://railscasts.com/episodes/307-elasticsearch-part-2
然后从上到下浏览轮胎http://karmi.github.io/retire/
