使用Ruby on Rails集成Shipping

在我的购物车中包含运费报价的最佳方法是什么？

我的网站的基本流程是

1.) User selects products 2.) User is shown cart 3.) repeat 1 and 2 until User wants to pay 4.) collect user details ( email, address where items will be shipped to ) 5.) make payment via active merchant 6.) order is submitted to distributor. 

我想插入运送信息，以便用户可以通过活跃的商家支付他的购买+运费。

 1.) User selects products 2.) User is shown cart 3.) repeat 1 and 2 until User wants to pay 4.) collect user details ( email, address where items will be shipped to ) 5.) calculate the cost of shipment, add cost to cart, show to user; 6.) make payment via active merchant 7.) order is submitted to distributor. 

有没有gem或插件来帮助我，如果不是……我怎么能这样做？

谢谢

看看active_shipping gem：

它是Shopify的另一个提取（如ActiveMerchant）
