rails设计登录模型的检查类

Question

I have multiple models which are using devise like Admin, Student and Counselor

I don't want to use roles as it 'll complicate things in this case.

I want to use one layout and show menus etc. depending upon class of model like

= render "shared/#{resource.class}_menu"

Is there way that I can get class of logged in object without if else conditions like we do in after_sign_in_path_for etc.

So what I do in this case where you want to have different areas for Admin, Student and Counselor

you can namespace each role or log in like this

#config/routes.rb
Rails.application.routes.draw do

  devise_for :admins, :controllers => { registrations:  'admins/registrations',
                                       sessions:        'admins/sessions',
                                       passwords:       'admins/passwords',
                                       confirmations:   'admins/confirmations'
  }
  authenticate :admin do
    namespace :admins do
      ....
      root :to => 'something#index'
    end
  end

  devise_for : students, :controllers => { registrations:   'students/registrations',
                                           sessions:        'students/sessions',
                                           passwords:       'students/passwords',
                                           confirmations:   'students/confirmations'
  }
  authenticate :student do
    namespace :students do
      ....
      root :to => 'something#index'
    end
  end

Now you can create the devise model for each namespace.

#app/controllers/admin_controller.rb
class AdminController < ApplicationController
  before_filter :authenticate_admin!

end

For Devise controllers you can use them like tihs

#app/controllers/users/sessions_controller.rb
class Users::SessionsController < Devise::SessionsController

end

For basic application controllers, you can use them like this.

#app/controllers/users/somethings_controller.rb
class Users::SomethingsController < UserController
...
end

I hope that this is able to help you
