Question

我有两张桌子。这是我的数据模式。

 create_table "comments", force: true do |t|
    t.integer  "movie_id"
    t.string   "user_comment"
    t.string   "user"
    t.datetime "created_at"
    t.datetime "updated_at"
  end

  create_table "movies", force: true do |t|
    t.string   "title"
    t.integer  "year"
    t.text     "cast"
    t.string   "director"
    t.string   "category"
    t.datetime "created_at"
    t.datetime "updated_at"
    t.integer  "like"
    t.integer  "dislike"
    t.string   "genre"
    t.integer  "rating"
  end

end

我有两个模特，电影＆amp;评论模型/ movie.rb

class Movie < ActiveRecord::Base
    has_many :comments
    include Tire::Model::Search
    include Tire::Model::Callbacks
    after_touch() { tire.update_index }
    mapping do
        indexes :title,boost: 100
        indexes :year,:analyzer => 'snowball'
        indexes :cast,:analyzer => 'snowball'
        indexes :user_comment
    end

    def self.search(params)
        tire.search(load: true) do |s|
            s.query {string "*#{params[:query]}*"} if params[:query].present?
            s.filter :range,year: {lte: 2004}
           end
    end

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

  def user_comment
    movie.comments.user_comment
  end
 end

模型/ comment.rb

class Comment < ActiveRecord::Base
    belongs_to :movie,touch: true
end

搜索控制器以搜索查询。控制器/ search_controller.rb

class SearchController < ApplicationController
  def index
    if(params[:query]).present?
    @results=Movie.search(params)
    else
    @results=[]
    end
  end
end

视图/搜索/ index.html.erb

<h1>Search#index</h1>
<p>Find me in app/views/search/index.html.erb</p>


    <%= form_tag search_index_path, method: :get do %>
      <p>
        <%= text_field_tag :query, params[:query] %>
        <%= submit_tag "Search", name: nil %>
      </p>
    <% end %>
    <% if @results %>
    <% @results.each do |fetchresults| %>
    <%= fetchresults.title %> 
    <%= fetchresults.year %>
    <%= fetchresults.director %>

    <br/>
    <% end %>
    <% end %>

我正在尝试使用轮胎在电影控制器中搜索评论。当我试图运行命令时： - rake environment tire：import CLASS =“Movie”FORCE =“true”

显示错误： -

[IMPORT] Deleting index 'movies'

任何人都可以帮助我。我的任务是从评论表中搜索评论。＆安培;还有一件事是如何在我的视图中获得该评论的电影ID。感谢。

Answer 1

似乎问题在于您的方法

  def user_comment
    movie.comments.user_comment
  end

应该是

  def user_comment
    comments.user_comment
  end

如何使用轮胎弹性搜索搜索活动记录关系。（has_many，belongs_to）
