destroy_user_session雖然routes.rb配置設計沒有destroy_user_session路線
# routes.rb #
devise_for :users, :controllers => { :omniauth_callbacks => "users/omniauth_callbacks" }
root :to => 'home#home'
和耙給
$ rake routes
user_omniauth_callback /users/auth/:action/callback(.:format) {:action=>/facebook/, :controller=>"users/omniauth_callbacks"}
root / {:controller=>"home", :action=>"home"}
events GET /events(.:format) {:action=>"index", :controller=>"events"}
POST /events(.:format) {:action=>"create", :controller=>"events"}
new_event GET /events/new(.:format) {:action=>"new", :controller=>"events"}
edit_event GET /events/:id/edit(.:format) {:action=>"edit", :controller=>"events"}
event GET /events/:id(.:format) {:action=>"show", :controller=>"events"}
PUT /events/:id(.:format) {:action=>"update", :controller=>"events"}
DELETE /events/:id(.:format) {:action=>"destroy", :controller=>"events"}
users GET /users(.:format) {:action=>"index", :controller=>"users"}
POST /users(.:format) {:action=>"create", :controller=>"users"}
new_user GET /users/new(.:format) {:action=>"new", :controller=>"users"}
edit_user GET /users/:id/edit(.:format) {:action=>"edit", :controller=>"users"}
user GET /users/:id(.:format) {:action=>"show", :controller=>"users"}
PUT /users/:id(.:format) {:action=>"update", :controller=>"users"}
DELETE /users/:id(.:format) {:action=>"destroy", :controller=>"users"}
posts GET /posts(.:format) {:action=>"index", :controller=>"posts"}
POST /posts(.:format) {:action=>"create", :controller=>"posts"}
new_post GET /posts/new(.:format) {:action=>"new", :controller=>"posts"}
edit_post GET /posts/:id/edit(.:format) {:action=>"edit", :controller=>"posts"}
post GET /posts/:id(.:format) {:action=>"show", :controller=>"posts"}
PUT /posts/:id(.:format) {:action=>"update", :controller=>"posts"}
DELETE /posts/:id(.:format) {:action=>"destroy", :controller=>"posts"}
這怎麼能是可能不會出現在我的路線？
