Django模型有两个主键

Question

我在表中有两个主键我知道django在同一个表中不支持多个PK我使用了unique_identifier但是当我执行syncdb时所有列都没有创建

class SODIOrder(models.Model):
    sodi_order_num = models.CharField(max_length=50, primary_key=True)
    sodi_order_version = models.CharField(max_length=50,primary_key=True)
    service_identifier = models.CharField(max_length=50)
    telephone_number = models.CharField(max_length=12)
    insert_timestamp = DateTimeUTCField(auto_now_add=True)

    class Meta:
        unique_together = (("sodi_order_num","sodi_order_version"))

sodi_order_version 没有创建任何人都可以帮我这个？

Answer 1

primary_key=True从模型字段中删除并更改unique_together为tuple of tuples:

class SODIOrder(models.Model):
    sodi_order_num = models.CharField(max_length=50)
    sodi_order_version = models.CharField(max_length=50)
    service_identifier = models.CharField(max_length=50)
    telephone_number = models.CharField(max_length=12)
    insert_timestamp = DateTimeUTCField(auto_now_add=True)

    class Meta:
        unique_together = (("sodi_order_num","sodi_order_version"),)
