我一直关注this Railscast在新的测试应用中实施Active Merchant并且进展顺利,但现在我正在尝试将我对主应用程序所做的内容添加到其中。
点击我的测试应用中的“添加到购物车”时,它会重定向到当前购物车并按预期列出该项目。
在我的主应用上点击添加到购物车链接重定向到:
http://mainapp.dev/line_items?product_id=1
line_items控制器如下所示:
class LineItemsController < ApplicationController
def create
@product = Product.find(params[:product_id])
@line_item = LineItem.create!(:cart => current_cart, :product => @product, :quantity => 1, :unit_price => @product.price)
flash[:notice] = "Added #{@product.name} to cart."
redirect_to current_cart_url
end
end
“添加到购物车”链接如下所示:
<%= link_to "Add to Cart", line_items_path(:product_id => product), :method => :post, :class => "product_actions" %>

我无法弄清楚为什么它想要重定向到订单项索引而不是创建,代码是相同的。
编辑 - 路线
get "cart" => "carts#show", :as => "current_cart"
resources :orders
resources :line_items
resources :carts
resources :products
resources :order_transactions
编辑 - 取自我的应用程序控制器
def current_user
@current_user ||= User.find(session[:user_id]) if session[:user_id]
end
def current_cart
if session[:cart_id]
@current_cart ||= Cart.find(session[:cart_id])
session[:cart_id] = nil if @current_cart.purchased_at
end
if session[:cart_id].nil?
@current_cart = Cart.create!
session[:cart_id] = @current_cart.id
end
@current_cart
end
感谢任何帮助,非常感谢!

如果您通过单击“添加到购物车”链接将项目添加到购物车,则需要在LineItemsController控制器中调用创建操作,就像现在一样。
该方法的最后一行是
redirect_to current_cart_url
所以你确实按照自己的意愿重定向到current_cart,但是你说你没有重定向到当前的购物车,这实际上是胡说八道。
也许您尚未设置current_cart_url路径或视图或其他内容?
我不清楚你的实际问题是什么
Started GET "/line_items?product_id=1" for 127.0.0.1 at 2011-09-01 07:34:59 +0100

此后必须发生一些事情! 〜这是什么?
编辑 - 解决方案 对不起,我完全错过了显而易见的事。
<%= link_to "Add to Cart", line_items_path(:product_id => product), :method => :post, :class => "product_actions" %>
发出请求请求,而不是日志文件Started GET "/cart" for 127.0.0.1 at 2011-09-01 07:33:29 +0100
您正在向购物车添加商品,这意味着您正在更改服务器上的状态,这意味着您应该使用POST请求而不是获取(链接)请求,因此您应该使用表单(button_to将为您提供该表单)。除非您需要装载机器人的蜘蛛; /爬行器等......将东西添加到您的购物车中,您应该使用
<%= button_to 'Add to Cart', line_items_path(:product_id => product) %>
