表之间的关系：

产生报错的原因：

1、PatientPastHistoryInfoModel 一对多外键在这里，且设置了related_name = patientinfo

2、PatientInfoModel 一对一外键在这里，且设置了related_name = patientinfo

由于这两张表设置的是同一张表，就产生同名的冲突了，类似给PatientHealthInfoModel 创建两个虚拟字段名，都叫patientinfo，所以报错了

解决方法：

将其中一张表的外键字段进行修改：

models.ForeignKey(to='PatientHealthInfoModel', on_delete=models.CASCADE, null=True,related_name='patientinfo_new', related_query_name='patientinfo_new')

1、只要两张设置的名字不要一样就可以，

2、或直接不设置related_name和 related_query_name参数
