求一个需求的思路

Jun 23, 2016 pm 01:33 PM

我开发了一个广告联盟程序,要实现扣量的功能。就是比如本来有100的点击量,设置扣量20%之后就只显示80个。但是现在有个问题,我修改了扣量比例之后,用户再去查询原来的数据就会变,比如用户昨天真实点击有100个,我设置扣20%,就显示80个,今天我设置扣30%,如果用户去查昨天的数据就会显示70个,这样肯定不对啊。求思路,谢谢。

问题还是没说明白,显示70不对那是要显示多少?100?

折扣和时间关联起来不就可以了吗

根本就不能让用户知道被扣量了,昨天显示80,今天也应该显示80

根本就不能让用户知道被扣量了,昨天显示80,今天也应该显示80


最笨的方法就是建一个记录 扣量比例 + 时间 的表 读取数据的时候根据当时的时间找到当时的扣量比例显示数据

应该有三个字段
1.真实数
2.显示给用户看的
3.扣除的
显示给用户的是2。
1,3只是内部知道就可以了。

这个似乎只有和时间相关联。然后要现实的时候去读取对应时间的扣量比例计算出要现实的数据。
