“装载"是什么? Rails路由中的指令意思是什么? [英] What does the "mount" instruction mean in Rails routing?

问题描述

我在铁路网路由系统.

我已设置 Mercury 在我的Rails应用程序中使用.它将这一行添加到我的routes.rb配置文件中:

I have set up Mercury to use within my Rails application. It added this line to my routes.rb config file:

Appname::Application.routes.draw do
  mount Mercury::Engine => '/'

mount关键字是什么意思?

What does the mount keyword mean?

推荐答案

安装相当于Unix mount.
它实际上告诉应用程序该位置存在另一个应用程序(通常是 Rack 应用程序).

Mount within the Rails routes does the equivalent of a Unix mount.
It actually tells the app that another application (usually a Rack application) exists on that location.

它主要用于Rails引擎.

It is used mostly for Rails Engines.
