将航运与Ruby on Rails集成

Question

将运输报价包含在我的购物车中的最佳方法是什么？

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. 

我想插入一个发货信息，让用户可以付费通过积极的商人他的购买+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. 

是否有一个宝石或插件来帮助我在这里，如果没有......我怎么能做到这一点？

谢谢
斯特凡
