我刚刚跑了rails g active_admin:install，标准是它在我的 rails 应用程序上生成并安装了一堆文件。当我运行时，我得到了这个
/Users/judyngai/.rvm/gems/ruby-2.0.0-p195/gems/actionpack-4.0.0/lib/action_dispatch/routing/route_set.rb:409:in `add_route': Invalid route name, already in use: 'admin_root' (ArgumentError)
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
这就是我的路线现在的样子
Lintong::Application.routes.draw do
devise_for :admin_users, ActiveAdmin::Devise.config
ActiveAdmin.routes(self)
#get 'signup', to: 'students#signup'
root :to => 'students#signup'
resources :students #may not be necessary
devise_for :students
ActiveAdmin.routes(self)
# The priority is based upon order of creation: first created -> highest priority.
# See how all your routes lay out with "rake routes".
# You can have the root of your site routed with "root"
# Example of regular route:
# get 'products/:id' => 'catalog#view'
# Example of named route that can be invoked with purchase_url(id: product.id)
# get 'products/:id/purchase' => 'catalog#purchase', as: :purchase
# Example resource route (maps HTTP verbs to controller actions automatically):
# resources :products
# Example resource route with options:
# resources :products do
# member do
# get 'short'
# post 'toggle'
# end
#
# collection do
# get 'sold'
# end
# end
# Example resource route with sub-resources:
# resources :products do
# resources :comments, :sales
# resource :seller
# end
# Example resource route with more complex sub-resources:
# resources :products do
# resources :comments
# resources :sales do
# get 'recent', on: :collection
# end
# end
# Example resource route with concerns:
# concern :toggleable do
# post 'toggle'
# end
# resources :posts, concerns: :toggleable
# resources :photos, concerns: :toggleable
# Example resource route within a namespace:
# namespace :admin do
# # Directs /admin/products/* to Admin::ProductsController
# # (app/controllers/admin/products_controller.rb)
# resources :products
# end
end
我不能做rails s
我得到这个，同样的错误。我对路线不太熟悉，将继续阅读。我希望有人可以向我解释我做错了什么以及如何解决这个问题。
