问题描述
我有一个Rails应用程序，我使用docker卷使代码持久化。每当我在本地进行任何更改时，代码都会反映在docker容器中，但这些更改会反映在浏览器中。我不确定是否遗漏了任何东西。
现在，每次代码更改时，我都在重新启动容器，这不是正确的方法。 以下是我的docker-compose文件
data = {'dates': ['01.05.2020','01.05.2020','02.05.2020','03.05.2020','03.05.2020'],'amount' : [500,1000,2000,3000,4000,2300],'state' : ['ABC','ERT','ABC','XYZ','ZEQ','ERT']}
这是我的dockerfile

解决方法
通常，Rails不会在生产中对代码进行热重装（出于很好的原因，包括安全性，稳定性和速度），因此我会考虑切换到开发Rails环境。
接下来要警惕的是，docker可能不会以Rails会“注意到”文件已更改的方式（甚至在development中）接收更改。为此，请添加一行：
config.file_watcher = ActiveSupport::FileUpdateChecker
到您的production.rb文件（或在切换到development.rb的情况下）。
