将运输与 Ruby on Rails 集成

Question

在我的购物车中包含运费报价的最佳方法是什么？

我网站的基本流程是这样的

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.  

我想插入一个运费信息，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.

这里是否有 gem 或插件可以帮助我，如果没有...我该如何完成？

谢谢
斯蒂芬

查看 active_shipping gem：

它是从 Shopify 中提取的另一个（如 ActiveMerchant）
