添加了輪胎搜索寶石，如何添加多個索引？

Question

我有一個song.rb模型和genre.rb模型，我希望能夠搜索。

由於某種原因，輪胎只返回歌曲而非流派的搜索結果。

的代碼：

genre.rb 

class Genre < ActiveRecord::Base 
    has_many :genre_songs, :dependent => :destroy 
    has_many :songs, through: :genre_songs 

    include Tire::Model::Search 
    include Tire::Model::Callbacks 


end 

song_controller SNIPPIT

def index 
    if params[:query].present? 
     @songs = Song.search(params[:query], load: true) 
    elsif params[:genre] 
     @songs = Song.tagged_with(params[:genre]).paginate(:page => params[:page], :per_page => 15) 
     get_last_song 
    else  
     @songs = Song.order('id').order('plusminus desc nulls last').paginate(:page => params[:page], :per_page => 15) 
     #@songs = Song.tally.paginate(:page => params[:page], :per_page => 15) 
     get_last_song 
    end 
    end 

song.rb SNIPPIT

include Tire::Model::Search include Tire::Model::Callbacks 

個index.html.erb SNIPPIT

<%= form_tag songs_path, method: :get do %> 
    <p> 
    <%= text_field_tag :query, params[:query] %> 
    <%= submit_tag "Search", name: nil %> 
    </p> 
<% end %> 

Answer 1

在控制器：

@songs = Song.search(params) 

在歌曲模式：

def self.search(params) 
    tire.search(load: true, page: params[:page], per_page: 15) do 
     query { string params[:query], default_operator: "AND" } if params[:query].present? 

    end 
    end 

    def to_indexed_json 
    to_json(methods: [:genre_names]) 
    end 

    def genre_names 
    genres.map{ |g| g.name} 
    end
