Apache2 Passenger 重启时不更新 Ruby on Rails 类

Question

请原谅我，因为我对此有点陌生，但我继承了一个运行在 Apache2 Passenger 上的 Ruby On Rails web 应用程序。 我试图对在 DEV 上成功运行的应用程序做一些小改动，所以我已经部署到我们的 PROD 环境中。 但是，在部署并重新启动 Apache2 之后，我的所有更改都没有生效。 如果我改变

config.cache_classes = true

在 config/environments/production.rb 中设置为 false 然后一切都很好，但是我读到的所有内容都应该只在开发中设置为 false。

这让我相信一旦 Apache2 启动，缓存就不会被刷新。 关于这可能是什么的任何想法？ 我在 Apache2 错误日志（调试级别设置）中没有看到任何错误，下面是重新启动的片段。

Answer 1

我设法找出问题所在，在部署我的编码更改时，我在同一目录中备份了原始文件，只是在其上附加了一个日期，例如，我的 personnel_controller.rb 被重命名为 personnel_controller_20220926.rb 并且修改了 personnel_controller.rb 来自 dev被搬过来了。 无论出于何种原因，Rails（或者可能是 Apache）仍在中断旧文件而不是新文件。 一旦我将旧文件移动到应用程序目录之外的新位置并重新启动 Apache 一切正常。 总的来说，我对 Ruby on Rails 还是个新手，所以如果有人能解释为什么会这样，我很想知道。
