管理Rails应用程序配置设置的最佳方式是否保留在数据库中？ [英] Best way to manage Rails application configuration settings persisted in a database?

问题描述

我希望有人能建议使用数据库配置Rails应用程序的最佳实践（即将配置设置保存到数据库而不是平面文件）。我的推理是，我有一个应用程序，将运行在多个服务器，有一些配置设置是相当动态，我想改变它们，而不必在每个服务器上进行更改。

I was hoping someone could suggest some best practices for configuring Rails applications using a database (i.e. persisting configuration settings to a database rather than a flat file). My reasoning for this is that I have an application that will run on multiple servers and there are some configuration settings that are fairly dynamic and I would want to change them without having to make a change on every server.

在其他语言中，我已经看到这一点，使用一个简单的配置表（如名称/值对）和一个单例，暴露配置数据并定期刷新。

In other languages, I've seen this done by using a simple configuration table (like name/value pairs) and a singleton that exposes the configuration data and periodically gets refreshed. Is there a similar - or better - way to do this with Rails?

提前感谢。

推荐答案

不是最漂亮的解决方案，我敢肯定，但我们为内部应用程序做了一件事是创建一个配置字段，它只是一个包含序列化哈希的文本字段。然后我们从db进行反序列化。

Not the prettiest solution I'm sure, but one thing we've done for our internal apps is create a 'config' field that is simply a text field containing a serialized hash. Then we deserialize on load from the db.
