在哪里是存储应用程序参数的最佳位置：数据库，文件，代码...？ [英] Where is the best place to store application parameters : database, file, code...?

问题描述

我在开发一个Ruby on Rails网站，我有一个架构问题：我的应用程序需要一些参数，我想知道在哪里存储它们。

I am developing a Ruby on Rails website and I have an "architectural" question : my application needs some parameters and I'm wondering where to store them.

具体来说，我的应用程序接收一些请求，然后评估然后发送。因此，请求模型必须具有有关这些处理的属性：验证状态和发送状态。例如，验证状态可以接受，拒绝或等待。 发送状态可能是发送，等待，我必须将这些状态代码参数存储在某个地方，但我不知道什么是最好的解决方案。

In concrete terms, my application receive some requests which are evaluated and then sent. So, the Request model must have attributes concerning these treatments : a validation status and a sending status. For instance, validation status can be "accepted", "rejected" or "waiting". Sending status can be "sent", "waiting", "error during sending" or stuff like that. I have to store those status codes parameters somewhere, but I don't know what is the best solution.

我可以为每个模型创建一个模型，并将它们存储在数据库（例如，具有活动记录模型ValidationStatus），但是：创建用于存储这样的数据的数据库/模型是否会过多？

I could create a model for each one and store them in the database (and having an active record model ValidationStatus for instance) but : wouldn't it be a bite excessive to create a database/model for storing data like that?

I也可以只在代码中使用它们而不存储它们，我可以将它们存储在YAML文件中...

I could also just use them in the code without "storing" them, I could store them in a YAML file...

所以，一个更简单的问题：处理你的应用程序参数在RoR？

So, a more simpler question: how do you deal with your application parameters in RoR?

推荐答案

有很多全局配置插件，大多数是围绕加载的想法一个YAML文件在某点。检查此网页，此插件，甚至 Railscast 。

There are lots of global configuration plugins, most of them revolve around the idea of loading a YAML file at some point. Check this page, this plugin and even this Railscast.
