我正在关注教程http://fuelyourcoding.com/getting-started-with-jquery-mobile-rails-3/ http://fuelyourcoding.com/getting-started-with-jquery-mobile-rails-3/将直接搭建的 Rails 3 应用程序中的视图转换为 jquery 移动前端。
创建新记录后，我将传递到显示视图，并实际看到显示视图的结果，如显示的记录的两个新创建的字段一样，但是，URL 是http://localhost:3000/货币 http://localhost:3000/currencies在浏览器中。当我查看源代码时，源实际上是索引视图而不是浏览器中呈现的显示视图，这相当奇怪。有什么想法为什么会发生这种情况吗？
