ruby-on-rails - 如何将 PGSeaerch 结果链接到嵌套资源中的索引页？

Question

我终于想出了如何实现 pg_search 的多搜索功能。

但是我在制作一个可用的搜索页面时遇到了问题，该搜索页面显示返回到适当嵌套页面的链接。

如何传递正确的 ID，以便链接到嵌套 View 。

所以像这个 link_to

myapp.com/artists/1/albums

到目前为止我得到这个错误(我似乎无法传递艺术家 ID)

No route matches {:controller=>"albums", :artists=>nil}

Rails 新手请帮忙:)

控制者

class ResultsController < ApplicationController

  def index
    @results = PgSearch.multisearch(params[:query]).paginate( :page => params[:page] )
    @artists = PgSearch.multisearch(params[:query]).where(searchable_type: "Artist")
    @albums = PgSearch.multisearch(params[:query]).where(searchable_type: "Album")
  end

end

观点

<% if @results.any? %>

<% if @artists.any? %>

      <div class="maintitle">Artists</div>

      <% @results.each do |pg_results| %>
        <% if pg_results.searchable_type == "Artist" %>
          <div class="span3">

            #### How can I link to the Albums index page
            <%= link_to pg_results.searchable.name, 
                artist_albums_path(@artists) %>


          </div>       
        <% end %>
      <% end %>

<% end %>

<% if @albums.any? %> 

    <div class="maintitle">Albums</div>

    <div class="row">
      <% @results.each do |pg_results| %>
        <% if pg_results.searchable_type == "Album" %>

          ####How can I link to the Albums index page
          <%= link_to pg_results.searchable.name,  %>       

      <% end %>
    <% end %>
  </div>

<% end %>

<% end %>

模型

class Artist < ActiveRecord::Base
  attr_accessible :name

  has_many :albums
  has_many :songs, :through => :albums

  include PgSearch
  multisearchable :against => [:name],
    using: {tsearch: {dictionary: "english"}}

end

class Album < ActiveRecord::Base
  attr_accessible :name, :artist_id

  belongs_to :artist
  has_many :songs

  include PgSearch
  multisearchable :against => [:name],
    using: {tsearch: {dictionary: "english"}}
    associated_against: {artist: [:artist_id, :name]}

end

路线

Music::Application.routes.draw do

resources :artist do
  resources :albums
end

resources :results

end

架构

create_table "pg_search_documents", :force => true do |t|
  t.text     "content"
  t.integer  "searchable_id"
  t.string   "searchable_type"
  t.datetime "created_at",      :null => false
  t.datetime "updated_at",      :null => false
end

Answer 1

这是我链接到索引页的解决方案。有点乱，如果有人有更简单的解决方案。请发表评论:)

 <% @results.each do |pg_results| %>
    <% if pg_results.searchable_type == "Artist" %>
      <div class="span3">

        #### This is how I linked to the ALBUMS INDEX
        <%= link_to pg_results.searchable.name, 
        {:action => "index", controller => "albums", :artist_id => => pg_results.searchable}


      </div>       
    <% end %>
 <% end %>
