rails 3.1.1自动完成

我正在尝试在Rails 3.1下运行自动完成功能 .

https://github.com/crowdint/rails3-jquery-autocomplete

我一直在关注这个完整的应用程序示例并更改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），解压缩并将js复制到我的app / assets / javascript目录中，将css＆images目录复制到app / assets / stylesheets中 .

然后我 Build 了一个链接，所以我可以将它作为jquery-ui引用

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中添加了一个指向我的css的链接

*= require_self
 *= require jquery-ui
 *= require_tree .

我创建了品牌模型并迁移并添加了种子数据，例如示例 .

然后我根据教程向欢迎控制器添加了以下行：

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工作的表单，我的服务器输出中也没有错误：

我在这里错过了什么？是否有更新的Rails 3.1插件或更好的教程？
