如何在Django中设置唯一字段? [英] How can I set the field unique in django?

问题描述

我有一个模型课:

class PysicalServer(models.Model):

    serial_number = models.CharField(max_length=64)  # I want to add the unique
    name = models.CharField(max_length=16)

我知道使用primary_key可以设置唯一，但是serial_number不是我的id字段，我不能使用primary_key，还有其他可以设置字段唯一的属性吗?

I know use the primary_key can set unique, but the serial_number is not my id field, I can not use the primary_key, is there other property I can set field unique?

推荐答案

只需添加 unique = True serial_number = models.CharField(max_length = 64，unique = True)在此处查看更多信息 https://docs.djangoproject.com/en/1.11/ref/models/fields/#unique

just add unique=True serial_number = models.CharField(max_length=64, unique=True) see more information here https://docs.djangoproject.com/en/1.11/ref/models/fields/#unique
