可安装的引擎安装在什么路径上 [英] What path is a mountable engine mounted on

问题描述

我需要从可安装引擎的布局内部了解它当前正在安装的路径。

I need to know, from inside of a layout of a mountable engine, what path it's currently being mounted on. What would be the way to do it?

例如我的routes.rb包含以下行：

E.g. my routes.rb contains the following line:

  mount BackendCore::Engine => "/backend"

从BackendCore内部，我需要访问 / backend的值。

From inside of the BackendCore, I need the access to the value of "/backend".

推荐答案

更新：这可能仅适用于Rails 3！

UPDATE: this probably applies to Rails 3 only!

我找到了解决方案：

Rails.application.routes.named_routes[:backend_core].path #=> "/backend"
