奇異路由服務參數：object_id而不是：id

Question

假設我有一個名爲invoice的對象。在routes.rb我

resources :invoices do 
    get "pay" 
end 

當我運行rake routes，路線作爲

invoice_pay GET /invoices/:invoice_id/pay(.:format) invoices#pay 

生成和參數是:invoices_id而不是:id

如果我用一根火柴聲明：

match "invoices/:id/pay" => "invoices#pay", :via => :get 

我得到：

GET /invoices/:id/pay(.:format)   invoices#pay 

在我看來，該航線應該是pay_invoice_path(@invoice)，但是，我還沒有找到適合此文檔。有什麼建議麼？

Answer 1

我認爲你正在試圖做的是

resources :invoices do 
    get "pay", :on => :member 
end
