ruby-on-rails – 如何在同一用户模型中使用Devise和ActiveAdmin

devise_for :users,ActiveAdmin::Devise.config
devise_for :users

>rake routes

ArgumentError: Invalid route name,already in use: 'new_user_session'
You may have defined two routes with the same name using the `:as` option,or you may be overriding a route already defined by a resource with the same naming. For the latter,you can restrict the routes created with `resources` as explained here:
http://guides.rubyonrails.org/routing.html#restricting-the-routes-created

我发现这个 http://dan.doezema.com/2012/02/how-to-implement-a-single-user-model-with-rails-activeadmin-and-devise/

但我最终这样做了

Devise 3.4.1
ActiveAdmin 1.0.0.pre1
Rails 4.2.1

的routes.rb

devise_for :admin_users,{class_name: 'User'}.merge(ActiveAdmin::Devise.config)
  ActiveAdmin.routes(self)

  devise_for :users
  resources :users

application_controller.rb

def access_denied(exception)
    redirect_to root_path,alert: exception.message
  end

配置/初始化/ active_admin.rb

config.authorization_adapter = ActiveAdminAdapter
config.on_unauthorized_access = :access_denied

(并将所有方法从_user更改为admin_user.)

应用程序/模型/ active_admin_adapter.rb

class ActiveAdminAdapter < ActiveAdmin::AuthorizationAdapter
  def authorized?(action,subject = nil)
    user.admin == true
  end
end

和

rails generate migration add_admin_to_users admin:boolean
