如何将PGSeaerch结果链接到嵌套资源中的索引页？ [英] How to Link PGSeaerch results to Index Page in Nested Resources?

问题描述

我终于想出了如何实现pg_search的多重搜索功能。

但是我在制作一个显示链接的可用搜索页面时遇到了麻烦返回到适当的嵌套页面。

But I'm having trouble making a usable search page that displays links back to the appropriate nested pages.

如何传递正确的ID，以便可以链接到嵌套视图。

How can I pass the proper id so I could link to the nested views.

所以类似于此link_to

myapp.com/artists/1/albums

到目前为止，我收到此错误（我似乎无法通过艺术家ID）

So far I get this error(i cant seem to pass the artist id)

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

控制器

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

视图

<% 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

SCHEMA

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

推荐答案

这是我的解决方案链接到索引页面。如果有人有更简单的解决方案，那有点混乱。请发表评论：）

This was my solution to linking to the index page. Kind of messy, if someone has an easier solution. please leave a comment :)

 <% @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 %>
