Apache2 Passenger 重啟時不更新 Ruby on Rails 類

Question

請原諒我，因為我對此有點陌生，但我繼承了一個運行在 Apache2 Passenger 上的 Ruby On Rails web 應用程序。 我試圖對在 DEV 上成功運行的應用程序做一些小改動，所以我已經部署到我們的 PROD 環境中。 但是，在部署並重新啟動 Apache2 之后，我的所有更改都沒有生效。 如果我改變

config.cache_classes = true

在 config/environments/production.rb 中設置為 false 然后一切都很好，但是我讀到的所有內容都應該只在開發中設置為 false。

這讓我相信一旦 Apache2 啟動，緩存就不會被刷新。 關於這可能是什么的任何想法？ 我在 Apache2 錯誤日志（調試級別設置）中沒有看到任何錯誤，下面是重新啟動的片段。

Answer 1

我設法找出問題所在，在部署我的編碼更改時，我在同一目錄中備份了原始文件，只是在其上附加了一個日期，例如，我的 personnel_controller.rb 被重命名為 personnel_controller_20220926.rb 並且修改了 personnel_controller.rb 來自 dev被搬過來了。 無論出於何種原因，Rails（或者可能是 Apache）仍在中斷舊文件而不是新文件。 一旦我將舊文件移動到應用程序目錄之外的新位置並重新啟動 Apache 一切正常。 總的來說，我對 Ruby on Rails 還是個新手，所以如果有人能解釋為什么會這樣，我很想知道。
