Django的模型有两个主键

Question

我有一个表中的两个主键我知道Django不支持多PK在同一个表 我用unique_identifier但是当我做执行syncdb所有列不创建

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助我？

Answer 1

从模型字段删除primary_key=True和改变unique_together为tuple of tuples这样的：

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"),)
