如何将Devise和ActiveAdmin用于相同的用户模型？
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模型中只为管理员设置一个admin标志。）我尝试将第二行添加到routes.rb
devise_for :users, ActiveAdmin::Devise.config devise_for :users
但是当我试图列出路线时，它给出了一个错误
>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
我已经创建了一个授权适配器，它只检查user.admin == true ，这对ActiveAdmin工作正常。 https://github.com/activeadmin/activeadmin/blob/master/docs/13-authorization-adapter.md
我发现了这个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
Rails 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
