【问题描述】：
我正在尝试在 Rails 3.1 下实现自动完成功能。
https://github.com/crowdint/rails3-jquery-autocomplete
我一直在关注这个完整的应用示例并更改 Rails 3.1 的相关部分，但它仍然无法正常工作。
https://github.com/crowdint/rails3-jquery-autocomplete-app
这是我的 applicaion.js 文件
//= require jquery
//= require jquery_ujs
//= require jquery-ui
//= require autocomplete-rails
//= require_tree .
我已经下载了 jquery 1.8.16（勾选了自动完成功能），解压缩并将 js 复制到我的 app/assets/javascript 目录中，并将 css 和图像目录复制到 app/assets/stylesheets 中。
然后我创建了一个链接，以便我可以将其引用为 jquery-ui
ln -s jquery-ui-1.8.16.custom.min.js jquery-ui.js
与 CSS 相同
ln -s jquery-ui-1.8.16.custom.css jquery-ui.css
然后我在 application.css 中放了一个指向我的 css 的链接
*= require_self
*= require jquery-ui
*= require_tree .
我创建了品牌模型并像示例一样迁移并添加了种子数据。
然后我按照教程将以下行添加到我的欢迎控制器中：
autocomplete :brand, :name
我修复了 routes.rb 文件并编辑了表单。
我得到的是没有自动完成功能的表单，我的服务器输出也没有错误：

我在这里缺少什么？ 是否有更新的 Rails 3.1 插件或更好的教程？
