“没有路线匹配..”尝试从购物车删除商品时出错

发布于 2024-11-03 20:32:10 字数 534 浏览 0 评论 0原文

我有一个产品购物车（称为“line_items”），我正在尝试添加一个按钮来减少购物车中的商品数量：

3x  Coke $2.97  (-)

这是“(-)”部分的代码：

<%= button_to '(-)',  line_item, :confirm => 'Are you sure?', 
:method => :destroy, :product_id => line_item.product_id %>

我的 line_item.destroy 函数很简单，只是减少数量，然后重定向回主页。在测试中，当我尝试单击按钮时，出现此错误：

ActionController::RoutingError (No route matches "/line_items/61")

看来系统正在尝试访问 line_item 的 URL，而不是像我想象的那样遵循我在控制器中设置的销毁函数会的。有什么想法如何解决这个问题吗？

I have a shopping cart of products (called "line_items"), and I'm trying to add a button to decrease the amount of something from the cart:

3x  Coke $2.97  (-)

Here's the code for the "(-)" portion:

<%= button_to '(-)',  line_item, :confirm => 'Are you sure?', 
:method => :destroy, :product_id => line_item.product_id %>

My line_item.destroy function is pretty simple, it just decrements the quantity and then redirects back to the homepage. In testing, when I try to click the button, I get this error:

ActionController::RoutingError (No route matches "/line_items/61")

So it appears that the system is trying to visit the URL for the line_item, instead of following the destroy function I've set up in the controller it like I thought it would. Any ideas how to fix that?
