Rails3嵌套的路線，更新重定向到問題

Question

我試圖讓我的路由在更新發票後正常工作。

我有很多發票的訂單，並在我的routes.rb

resources :orders do 
resources :invoices 
end 

resources :invoices 

而在我的發票控制器如下：

def update 
    @invoice = Invoice.find(params[:id]) 
    respond_to do |format| 
     if @invoice.update_attributes(params[:invoice]) 
     format.html { redirect_to(invoice_path(@invoice), :notice => 'Invoice was successfully updated.') } 
     else 
     format.html { render :action => "edit" } 
     end 
    end 
    end 

我可以創建通過發票：

/orders/1/invoices/new 

但是當我保存或更新時，我發送到：

/invoices/1 

我要回重定向到訂單發票路徑：

/orders/1/invoices/1 

也試圖改變重定向到：

redirect_to(order_invoice_path(@order, @invoice), :notice => 'Invoice was successfully updated.') 

這工作，但它向我發送了錯誤的網址訂單ID與發票ID相同...

任何幫助表示讚賞。

如果我嘗試在我的發票控制器下面，我結束了一個錯誤太..

redirect_to(order_invoice_path(@order, @invoice)

No route matches {:action=>"show", :controller=>"invoices", :order_id=>nil, :id=>#<Invoice id: 6, order_id: 17, invoice_id: nil, created_at: "2011-06-26 17:49:01", updated_at: "2011-06-26 17:49:01">}

看來你做的以下在您的控制器中：

redirect_to(order_invoice_path(@order, @invoice), :notice => 'Invoice was successfully updated.') 

Bu你是否在某個地方設置了@order？

不管結果如何，你最好這樣做：

redirect_to(order_invoice_path(@invoice.order, @invoice), :notice => 'Invoice was successfully updated.')
