我对 Rails 3.2 有一个非常奇怪的问题。我对“app/assets/javascripts”所做的任何编辑都不会对我的应用产生任何影响。我什至从该目录中完全删除了所有文件，并且脚本（应该已经消失）继续像以前一样运行。

这是我从“app/assets/javascripts”中删除所有 js 文件后的服务器日志

如您所见，javascript 资产没有被提供，但它们继续在应用程序中运行。这是怎么回事？？？

我尝试清空浏览器缓存，但没有帮助。

还有一件事。当文件存在时，我想要编辑的 javascript 动画看起来像是在工作两次。当我完全删除它时，它似乎只动画一次。

您可能已经预编译了资产并在开发中加载了两次，一次来自 root/app/assets，第二次来自 root/public/assets

但是假设您希望能够预编译资产（以在将它们部署到服务器之前测试它们是否会被编译）并且不想在每次进行预编译时都删除它们，您可以重命名预编译资产文件夹的前缀和：

config.assets.prefix = "/assets_dev"

把它放在你的 development.rb 中，你可以运行 assets_precompile 但它们不会加载到应用程序中。

资产的 URL 将显示<link href="/assets_dev/bootstrap....并且不会查看assets文件夹。
