如何使用 Devise 根据用户的角色重定向用户的主(根)路径? [英] How can I redirect a user's home (root) path based on their role using Devise?

问题描述

我正在开发一个项目管理应用程序，在该应用程序中，我有project_managers 和客户.我正在使用 Devise 和 CanCan 进行身份验证/授权.

I'm working on a project management app, and in the app, I have project_managers and clients. I'm using Devise and CanCan for authentication/authorization.

登录后我应该在什么时候将用户重定向到他们自己的特定控制器/布局/视图?有没有办法检查 routes.rb 中的 current_user.role 并根据他们是项目经理还是客户来设置根(或重定向)?这是我可以在 Devise 的某个地方做出的改变吗?

At what point after login should I be redirecting the user to their own specific controller/layout/views? Is there a way to check for current_user.role in routes.rb and set the root (or redirect) based on whether or not they're a project manager or a client? Is this a change I can make in Devise somewhere?

在此先感谢您的帮助！--马克

推荐答案

你的 routes.rb 文件不知道用户拥有什么角色，所以你将无法使用它分配特定的根路由.

Your routes.rb file won't have any idea what role the user has, so you won't be able to use it to assign specific root routes.

您可以做的是设置一个控制器(例如，passthrough_controller.rb)，它可以读取角色并重定向.像这样:

What you can do is set up a controller (for example, passthrough_controller.rb) which in turn can read the role and redirect. Something like this:

# passthrough_controller.rb
class PassthroughController < ApplicationController
  def index
    path = case current_user.role
      when 'project_manager'
        some_path
      when 'client'
        some_other_path
      else
        # If you want to raise an exception or have a default root for users without roles
    end

    redirect_to path     
  end
end

# routes.rb
root :to => 'passthrough#index'

这样，所有用户都将有一个入口点，然后根据他们的角色将他们重定向到适当的控制器/操作.

This way, all users will have one point of entry, which in turn redirects them to the appropriate controller/action depending on their role.
