activerecord信誉系统gem阻止保存新对象

我正在跟踪railscast添加一个活动记录声誉系统。（）我有一件模型衬衫，我希望用户能够投票。我用以下内容更新了我的文件：

gem 'activerecord-reputation-system', require: 'reputation_system'

我运行了一个bundle安装并重新启动了服务器。现在，当我尝试创建一件新衬衫时，我收到一个通知，即即使我输入了一个名称，衬衫仍缺少一个名称，并且我无法创建一件新衬衫。一旦我移除gem并运行bundle安装，一切都会恢复正常，我就能够毫无问题地创建一件衬衫。知道这是怎么回事吗

以下是日志：

使用以下gem解决了这个问题

gem 'activerecord-reputation-system', github: 'NARKOZ/activerecord-reputation-system', branch: 'rails4'

---

由于3.0版activerecord信誉系统支持Rails 4，并且该漏洞已在3.0.1版中修复，因此建议使用原始的

activerecord信誉系统

，因为它现在支持Rails 4，并且该漏洞已修复。
