rails-jquery-autocomplete 和acts_as_taggable 表单路由

Question

Acts_as_taggable 工作正常。我执行以下操作将rails-jquery-autocomplete 添加到我的网络应用程序中。我在生产中使用 Rails 4.2.2/Heroku。

add gem 'rails-jquery-autocomplete' to gem file
bundle install
heroku run bundle install

updated my application.js file to 

//= require jquery
//= require jquery_ujs
//= require jquery-ui/autocomplete
//= require autocomplete-rails
//= require bootstrap
//= require turbolinks
//= require_tree .

and pushed to Heroku

// Model
class Photo < ActiveRecord::Base
  acts_as_taggable_on :tags
end

// Controller
class PhotosController < ApplicationController
  autocomplete :tag, :name, :class_name => 'ActsAsTaggableOn::Tag'
  ...
private
  def photo_params
    params.require(:photo).permit(:picture, :title, :tag_list)
  end
end

// Routes
get 'tags/:tag', to: 'photos#index', as: :tag
resources :photos do
    get :autocomplete_tag_name, :on => :collection
end

//View  

<% form_for :photo, url: photos_path, html: {multipart: true } do |form| %>
  <%= f.file_field :picture %>
  <%= f.text_field :title %> 
  <%= form.label :tag_list, "Tags" %>
  <%= form.autocomplete_field :tag_list, autocomplete_tag_name_photos_path, :"data-delimiter" => ', ' %>
<% end %>

表单已保存，标签和照片已添加到数据库中，但自动完成功能根本不起作用。

我经历过thesetopics，但他们没有帮我找到答案。

我忘记添加 gem 'jquery-ui-rails'。
