为“ModelName”获取未定义的方法`param_key'：ActiveModel :: Name

Question

我的应用程序运行良好，使用ruby 1.9.2 -p290，rails 3.0.10 & refinerycms 1.0.9。 我已经使用acts_as_commentable gem进行评论。我添加了一个新的gem并运行软件包安装，之后我无法添加评论。投掷错误以下

undefined method `param_key' for "ModelName":ActiveModel::Name 

我也评论了新添加的gem和运行bundle安装。但问题仍然存在。以下是结果为 束秀

Answer 1

固定为起诉通过降级decent_exposure宝石。

由于将decent_exposure gem升级到其最新版本，此应用程序env不支持此问题并且由refinerycms在内部使用，因此引发此问题。

将gem明确添加到Gemfile中，其版本由我的应用程序环境支持。
