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

问题描述

我开发一个Ruby on Rails的网站，我有一个建筑的问题：我的应用程序需要一些参数，我想知道哪里来存储它们

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.

在具体而言，我的应用接收的评估，然后发送一些请求。因此，请求模型必须有关于这些治疗方法属性：验证状态和发送状态。例如，验证状态可以是接受，拒绝的或等的。 发送状态可以是发送，等，发送的过程中错误或类似的东西。我要存储这些状态codeS参数的地方，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.

我可以创建为每一个模型，并将其存储在数据库中（并具有实例的活动记录模式ValidationStatus），但：不会是一咬牙过度创建用于存储这样的数据的数据库/模式？

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?

我也可以只使用他们在code没有储存起来，我可以将它们存储在YAML文件...

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：你怎么应对的RoR应用程序的参数

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

推荐答案

有许多全局配置的插件，其中大部分围绕在某些时候加载YAML文件的想法。检查此页面，的这个插件即使这样的 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.
