form_for soulève une "RoutingError"

[My Hotel]

Oui, pour le nom du modèle, je me suis aussi dit que ça allait foutre la merde, mais j'avais aucune inspiration... Bref, si tu as un nom alternatif à me proposer

Sinon, au niveau de mon routes.rb, ça donne ça :

root :to => "pages#home"

match '/signup',  :to => 'users#new'

match '/signin',  :to => 'sessions#new'

match '/signout', :to => 'sessions#destroy'

resources essions

resources :users

resources :news

resources :comments

Et voici le résultat de rake routes :

comments_new GET    /comments/new(.:format)      {:controller=>"comments", :action=>"new"}

sessions_new GET    /sessions/new(.:format)      {:controller=>"sessions", :action=>"new"}

        root        /(.:format)                  {:controller=>"pages", :action=>"home"}

      signup        /signup(.:format)            {:controller=>"users", :action=>"new"}

      signin        /signin(.:format)            {:controller=>"sessions", :action=>"new"}

     signout        /signout(.:format)           {:controller=>"sessions", :action=>"destroy"}

    sessions GET    /sessions(.:format)          {:action=>"index", :controller=>"sessions"}

    sessions POST   /sessions(.:format)          {:action=>"create", :controller=>"sessions"}

 new_session GET    /sessions/new(.:format)      {:action=>"new", :controller=>"sessions"}

edit_session GET    /sessions/:id/edit(.:format) {:action=>"edit", :controller=>"sessions"}

     session GET    /sessions/:id(.:format)      {:action=>"show", :controller=>"sessions"}

     session PUT    /sessions/:id(.:format)      {:action=>"update", :controller=>"sessions"}

        news GET    /news/:id(.:format)          {:action=>"show", :controller=>"news"}

        news PUT    /news/:id(.:format)          {:action=>"update", :controller=>"news"}

        news DELETE /news/:id(.:format)          {:action=>"destroy", :controller=>"news"}

    comments GET    /comments(.:format)          {:action=>"index", :controller=>"comments"}

    comments POST   /comments(.:format)          {:action=>"create", :controller=>"comments"}

 new_comment GET    /comments/new(.:format)      {:action=>"new", :controller=>"comments"}

edit_comment GET    /comments/:id/edit(.:format) {:action=>"edit", :controller=>"comments"}

     comment GET    /comments/:id(.:format)      {:action=>"show", :controller=>"comments"}

     comment PUT    /comments/:id(.:format)      {:action=>"update", :controller=>"comments"}

     comment DELETE /comments/:id(.:format)      {:action=>"destroy", :controller=>"comments"}

Merci de te pencher sur mon problème, bye
