如何将 Devise 和 ActiveAdmin 用于相同的用户模型？

Question

我有 ActiveAdmin 和 Devise 与用户合作。我想使用 Devise 登录具有相同用户模型的常规非管理员用户。我怎样才能做到这一点？ （我想在 User 模型中有一个 admin 标志，仅供管理员使用。）我尝试将第二行添加到 routes.rb

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

但是当我尝试列出路线时它给出了错误

>rake routes
DL is deprecated, please use Fiddle
rake aborted!
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

我创建了一个仅检查user.admin == true 的授权适配器，它对ActiveAdmin 来说工作正常。 https://github.com/activeadmin/activeadmin/blob/master/docs/13-authorization-adapter.md

Answer 1

我找到了这个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

设计 3.4.1
ActiveAdmin 1.0.0.pre1
导轨 4.2.1

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

config/initializers/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。）

app/models/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
