Rails 中 RESTful 路由的更新操作(PATCH 或 PUT) [英] update action of a RESTful route in Rails (PATCH or PUT)

问题描述

我是 Ruby on Rails 的新手.为什么 Rails 中 RESTful 路由的更新操作映射到两个 HTTP 动词，即 PATCH 和 PUT?

I am a newbie to Ruby on Rails.why is the update action of a RESTful route in Rails is mapped to two HTTP verbs i.e, PATCH and PUT?

   PATCH  /articles/:id(.:format)      articles#update
   PUT    /articles/:id(.:format)      articles#update

更新资源时调用这两者中的哪个方法(一般CRUD)?

Which Method among the two is called when I update a resource(general CRUD )?

推荐答案

请求类型遵循 HTTP 标准.

It's done to follow HTTP standard for request types.

@Mikhail 如何从概念上提到:

How @Mikhail mentioned, conceptually:

• PATCH 是合适的请求类型，当您只想更新部分你的对象
• PUT 是一种标准方式，当您喜欢完全覆盖您的对象时新数据

• PATCH is a proper request type, when you want to update only part of your object
• PUT is a standard way when you like fully overwrite your object with new data

虽然在 Rails 中，这两个操作都可以通过单个 update 操作轻松完成，区别仅在于传递的 params，然后 Rails 使两条路线来覆盖标准，但实际上没有必要为此制作 2 个不同的控制器操作.

While in Rails both of this can be easily done with single update action and the difference is just in passed params, then Rails makes two routes to cover standards, but there is no real need in making 2 different controller action for that.

据我所知，Rails 默认使用 PUT，但您可以使用其中任何一个.只需遵循提到的概念规则

As I know Rails uses PUT as default, but you can use any of them. Just follow mentioned conceptual rule
