如何以编程方式列出 Rails 中的所有控制器 [英] How to programmatically list all controllers in Rails

问题描述

我正在尝试构建一个 RESTful 应用程序来实际管理许多类型的可配置对象，因此有大量的资源"类型，因此有很多控制器.我仍处于 POC 阶段，所以如果我能在第一个导航页面中显示所有控制器会很好，所以有什么简单的方法(可编程)来做到这一点?

I'm trying to build a RESTful app to actually manage many kind of configurable objects, so there are a large amount of "resource" types, and hence a lot of controllers. I'm still at the POC phase, so it will be nice if I can show all controllers in a first navigation page, so any easy way (programmable) to do that?

推荐答案

在 Rails 3.1+ 中:

In Rails 3.1+:

Rails.application.routes

如果你的 routes.rb 文件中有它们的路径，这将为你提供所有控制器、动作和它们的路由.

This will give you all the controllers, actions and their routes if you have their paths in your routes.rb file.

例如:

routes= Rails.application.routes.routes.map do |route|
  {alias: route.name, path: route.path, controller: route.defaults[:controller], action: route.defaults[:action]}
end

更新:对于Rails 3.2，日志引擎路径改变了，所以代码变成:

Update: For Rails 3.2, Journal engine path changed, so the code becomes:

routes= Rails.application.routes.routes.map do |route|
  {alias: route.name, path: route.path.spec.to_s, controller: route.defaults[:controller], action: route.defaults[:action]}
end

更新:仍在为 Rails 4.2.7 工作.要提取控制器列表(根据实际问题)，您只需提取控制器和 uniq

Update: Still working for Rails 4.2.7. To extract the list of controllers (per actual question), you can simply extract the controller and uniq

controllers = Rails.application.routes.routes.map do |route|
  route.defaults[:controller]
end.uniq
