原标题:Model objects versions in Django

I m building an e-commerce website. I have a Product and Order models. It s possible that a customer order a product and then the admin change its price or other fields before the customer actually get it.

A possible solution is to add a version field to the Product model. When the admin update a product field I ll add a timestamp and create a new object instead of updating the old one. An Order will have a reference to a specific product version.

Does this make sense? Will overriding the Product Save method be sufficient to make it work?

最佳回答

我这样做:

在表格中重复相关产品栏目。

当你在订单上添加产品时,copy从产品到订单的所有产品(如果你愿意,也列入FK)。 这样,行政部门就可以做他们想要做的一切(改变产品名称/价格/类别/名称),但产品价格/名称等将永远保持不变。

你可以按照你的建议,在产品中打一栏,但是这更加复杂。
