1、收入不全部报税，税银联网，即便通过淘宝京东拼多多等平台收款，客户不需要发票，交易流水还是在银行有记录。造成偷增值税和企业所得税的事实容易被大数据筛查。
2、A店铺卖货，用B公司开票
3、私户或者支付宝、微信发部分工资，协助员工少交或不交个税，没有代扣代缴个税。
4、出口退税问题，报关、核销问题。
5、工资高，社保入税政策要求以工资为基数交社保。
6、虚开骗取出口退税，被大数据筛查后，强制执行吊销营业执照，终生不能以个人名义成立公司。

Django change an existing field to foreign key
I have a Django model that used to look like this:class Car(models.Model): manufacturer_id = models.IntegerField()There is another model called Manufacturer that the id field refers to. However, I realized that it would be useful to use Django's built-in foreign key functionality, so I changed the model to this:class Car(models.Model): manufacturer = models.ForeignKey(Manufacturer)This change appears to work fine immediately, queries work without errors, but when I try to run migrations, Django outputs the following:- Remove field manufacturer_id from car - Add field manufacturer to carDoing this migration would clear all the existing relationships in the database, so I don't want to do that. I don't really want any migrations at all, since queries like Car.objects.get(manufacturer__name="Toyota") work fine. I would like a proper database foreign key constraint, but it's not a high priority.So my question is this: Is there a way to make a migration or something else that allows me to convert an existing field to a foreign key? I cannot use --fake since I need to reliably work across dev, prod, and my coworkers' computers.内容来源于 Stack Overflow, 遵循 CCBY-SA 4.0 许可协议进行翻译与使用。原文链接：Django change an existing field to foreign key
