ruby-on-rails-3 – 如何在Rails中路由[OPTIONS]？

resources :users
  match '/users',:controller => 'users',:action => 'options',:consTraints => {:method => 'OPTIONS'}

我能够[GET]我的用户.我想更新我的用户,我收到一个错误：

ActionController::routIngError (No route matches [OPTIONS] "/users/1"):

当我运行耙子路线这里是我给的路线：

users GET    /users(.:format)          users#index
          POST   /users(.:format)          users#create
 new_user GET    /users/new(.:format)      users#new
edit_user GET    /users/:id/edit(.:format) users#edit
     user GET    /users/:id(.:format)      users#show
          PUT    /users/:id(.:format)      users#update
          deletE /users/:id(.:format)      users#destroy
                 /users(.:format)          users#options {:method=>"OPTIONS"}

有人可以告诉我如何修复我的路由,@R_226_9447@做任何形式的REST调用？谢谢.
