这在我的道路上。 rb file:

resources :orders do
  member do
    get  confirm 
    get  cancel 
  end
end

Of course I wrote the confirm and cancel actions in my orders_controller.rb:

def confirm
  @order = Order.find(params[:id])
  #...
end

def cancel
  @order = Order.find(params[:id])
  #...
end

并且在我的“申请/调查/命令/”文件夹中创建了“confirm.html.erb”和“cancel.html.erb”。

但当我试图访问confirm_order_url或cancel_order_url时。 我总是犯这一rou错:

No route matches {:action=>"confirm", :controller=>"orders"}

Can t figure out what s missing! Any idea please?

PS: I m, using RoR v.3.1.0

EDIT#1: It seems the routes are set properly:

$ rake routes
[..]
 confirm_order GET    /orders/:id/confirm(.:format) {:action=>"confirm", :controller=>"orders"}
  cancel_order GET    /orders/:id/cancel(.:format)  {:action=>"cancel", :controller=>"orders"}
        orders GET    /orders(.:format)             {:action=>"index", :controller=>"orders"}
               POST   /orders(.:format)             {:action=>"create", :controller=>"orders"}
     new_order GET    /orders/new(.:format)         {:action=>"new", :controller=>"orders"}
    edit_order GET    /orders/:id/edit(.:format)    {:action=>"edit", :controller=>"orders"}
         order GET    /orders/:id(.:format)         {:action=>"show", :controller=>"orders"}
               PUT    /orders/:id(.:format)         {:action=>"update", :controller=>"orders"}
               DELETE /orders/:id(.:format)         {:action=>"destroy", :controller=>"orders"}
[...]

EDIT#2: Maybe when I call confirm_order_url Rails doesn t know how to generate the route which should be like "orders/:id/confirm" because @order.id hasn t been assigned yet. But I am calling this method after @order.save. Namely, here:

  if @order.save
  response = PAYPAL_EXPRESS_GATEWAY.setup_purchase(@order.price_in_cents,
  :ip                => @order.ip_address,
  :return_url        => confirm_order_url,
  :cancel_return_url => cancel_order_url 
  )
  redirect_to PAYPAL_EXPRESS_GATEWAY.redirect_url_for(response.token)

So this leads to a subquestion: is @order.id set after the call to @order.save? And if not, how can I set it properly before calling an helper method such ad confirmation_order_url?

SOLUTION Thanks to Jayendra Patil i fixed my code this way:

  if @order.save
  response = PAYPAL_EXPRESS_GATEWAY.setup_purchase(@order.price_in_cents,
  :ip                => @order.ip_address,
  :return_url        => confirm_order_url(@order),
  :cancel_return_url => cancel_order_url(@order) 
  )
  redirect_to PAYPAL_EXPRESS_GATEWAY.redirect_url_for(response.token)

我错误地认为,铁路可以猜测,而I号令称之为“成员”,因此,答案是把“顺序”作为成员路线的理由。 谢谢。
