Ruby on rails “论点错误”；“插入空字符串”；轨道

突然开始在我正在处理的项目中的某个特定控制器的所有操作上得到一个“实习空字符串”。这是工作正常，然后我开始改变一些位，它坏了，我似乎无法修复它现在。在进行任何更改之前，我已经将所有代码回滚到github版本，但这似乎并没有解决问题

任何帮助都将不胜感激

错误：

ArgumentError in Equipment itemsController#index

interning empty string

视图（我认为不太重要，因为代码在呈现页面时没有做到这一点）：

你好，世界

我在这个问题上已经讨论了好几个小时，错误似乎就在代码响应之后和操作“结束”之前呈现的操作结束时出现。

您的模板目录中有什么？您的一个模板似乎有一个空的区域设置，这导致模板引擎崩溃。

我认为Ruby 1.9允许插入空字符串，但Ruby 1.8不允许。虽然这似乎不是您的问题，但这可以解释为什么某些人会突然出现错误。

您用于访问导致错误的页面的确切URL是什么？谢谢。我有“_form..html.erb”。注意双点。我知道这一定很简单。
