我刚刚运行rails g active_admin:install
,标准是它生成并在我的rails应用程序上安装了一堆文件。当我跑步时,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
现在这是我的路线的样子
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
我做不到rails s
我得到了这个,同样的错误。我对路线不是很熟悉,并会阅读它。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。

听起来像是你大部分时间 - 只需仔细检查你的步数和输出
从一开始你就可以看到你在这个过程中的位置。
添加到您的gemfile
gem 'activeadmin'
安装
bundle install
运行安装生成器
rails generate active_admin:install
运行它应该吐出数据,告诉你在你的应用程序中创建了哪些文件。它看起来像:
invoke devise
generate No need to install devise, already done.
invoke active_record
create db/migrate/20130829160843_devise_create_admin_users.rb
create app/models/admin_user.rb
invoke rspec
create spec/models/admin_user_spec.rb
invoke factory_girl
create spec/factories/admin_users.rb
insert app/models/admin_user.rb
route devise_for :admin_users
gsub app/models/admin_user.rb
gsub config/routes.rb
insert db/migrate/20130829160843_devise_create_admin_users.rb
create config/initializers/active_admin.rb
create app/admin
create app/admin/dashboard.rb
create app/admin/admin_user.rb
insert config/routes.rb
generate active_admin:assets
create app/assets/javascripts/active_admin.js
create app/assets/stylesheets/active_admin.css.scss
create db/migrate/20130829160852_create_admin_notes.rb
create db/migrate/20130829160853_move_admin_notes_to_comments.rb
只要您看到该字符串,您就拥有了入门所需的文件。此时,您的路由中只有一个条目用于ActiveAdmin
现在迁移
bundle exec rake db:migrate
重新启动服务器,您应该能够登录。
现在设置模型
rails generate active_admin:resource ModelNameHere
答案 1 :(得分:0)
在您的路线文件中,您已添加ActiveAdmin.routes(self)
两次
尝试删除额外的一个并再次运行
可能是
的原因答案 2 :(得分:0)
我有同样的问题。通过在迁移活动管理员更改后重新启动我的服务器来修复它。
