Will_paginate无法加载页面，错误的URL

标签： javascript jquery ruby-on-rails ruby will-paginate

我正在尝试在项目中使用AJAX无限滚动来实现will_paginate gem。尝试使用它时，我在JS控制台中收到以下错误。

  

[错误]无法加载资源：服务器响应状态为404（未找到）（过滤器，第0行）

     

[错误]无法加载资源：服务器响应状态为404（未找到）（过滤器，第0行）

我所知道的：

  • 我在另一个项目中使用了这个确切的代码，它运行得很完美。
  • 我的vehicle #index用范围过滤初始输入，我怀疑这是错误的原因。我不知道如何通过它。

这是堆栈跟踪：
