我按照本教程中讨论的设计在我的本地主机上工作的每一步 - http://www.slideshare.net/wleeper/devise-and-rails upto page 8 of 22并且我期待与上面提到的相同的用户登录表单第 8 页，但除此之外，我收到此错误 -
如果我保留在 routes.rb 文件中的评论，
# 匹配 ':controller(/:action(/:id))(.:format)'
然后这个消息标志 -
当我取消注释此行时，它会显示此错误-
因为我来自 PHP 背景，所以对 Rails 的了解很少，但在理论之前仍然尝试一些实际测试，所以让我知道我到底做错了什么。
我的 routes.rb 文件 -
Prjmgt::Application.routes.draw do
devise_for :users
# The priority is based upon order of creation:
# first created -> highest priority.
# Sample of regular route:
# match 'products/:id' => 'catalog#view'
# Keep in mind you can assign values other than :controller and :action
# Sample of named route:
# match 'products/:id/purchase' => 'catalog#purchase', :as => :purchase
# This route can be invoked with purchase_url(:id => product.id)
# Sample resource route (maps HTTP verbs to controller actions automatically):
# resources :products
# Sample resource route with options:
# resources :products do
# member do
# get 'short'
# post 'toggle'
# end
#
# collection do
# get 'sold'
# end
# end
# Sample resource route with sub-resources:
# resources :products do
# resources :comments, :sales
# resource :seller
# end
# Sample resource route with more complex sub-resources
# resources :products do
# resources :comments
# resources :sales do
# get 'recent', :on => :collection
# end
# end
# Sample resource route within a namespace:
# namespace :admin do
# # Directs /admin/products/* to Admin::ProductsController
# # (app/controllers/admin/products_controller.rb)
# resources :products
# end
# You can have the root of your site routed with "root"
# just remember to delete public/index.html.
# root :to => 'welcome#index'
root :to => 'home#index'
# See how all your routes lay out with "rake routes"
# This is a legacy wild controller route that's not recommended for RESTful applications.
# Note: This route will make all actions in every controller accessible via GET requests.
match ':controller(/:action(/:id))(.:format)'
end
只需运行一个rake routes命令并找到这个 -
