Rails 控制器生命周期 [英] Rails controller lifecycle

问题描述

我想了解一下 Rails 中的对象生命周期，我可以指望每个请求都有新实例吗?说每个 Web 请求都会创建一个新的控制器实例是真的吗?(默认情况下)

I want to know a little about the object lifecyle in rails, can I count on new instance per request?, Is it true to say that each web request creates a new controller instance?(by default)

推荐答案

是的，您可以为每个请求依赖一个新的控制器实例.

Yes, you can rely on a fresh controller instance per request.

RailsGuides:

当您的应用程序收到请求时，路由将确定运行哪个控制器和动作，然后 Rails 创建一个实例该控制器并运行与操作同名的方法.

When your application receives a request, the routing will determine which controller and action to run, then Rails creates an instance of that controller and runs the method with the same name as the action.
