如何在Rails 3中创建动态根？ [英] How to create a dynamic root in Rails 3?

问题描述

我的网络应用中有管理员和普通用户。我想根据他们是谁来使他们的根（/）不同。可以从许多不同的页面访问根目录，因此，如果可以在routes.rb文件中进行此操作，将更加容易。这是我当前的文件。

I have admins and normal users in my webapp. I want to make their root (/) different depending on who they are. The root is accessed from many different pages, so it would be much easier if I could make this happen in the routes.rb file. Here is my current file.

ProjectManager::Application.routes.draw do
  root :to => "projects#index"
end

有人可以将我链接到一个示例，该示例可以显示我要进去的方向吗？有什么方法可以将逻辑放入路由文件中？感谢您的所有帮助。

Can someone please link me to an example that can show me the direction to go in? Is there any way to put logic into the routes file? Thanks for all the help.

推荐答案

您只需为根路由创建控制器。

You can just create controller for root route.

class RoutesController < ActionController::Base
  before_filter :authenticate_user!

  def root
    root_p = case current_user.role
      when 'admin'
        SOME_ADMIN_PATH
      when 'manager'
        SOME_MANAGER_PATH
      else
        SOME_DEFAULT_PATH
      end

    redirect_to root_p
  end
end

在您的route.rb中：

In your routes.rb:

  root 'routes#root'

PS该示例期望使用 Devise ，但您可以根据需要对其进行自定义。

P.S. example expects using Devise, but you can customize it for your needs.
