Question

我有一个拥有CustomUser的Django应用程序。我的模型看起来像

class CustomUser(AbstractBaseUser):
def get_short_name(self):
    pass

def get_full_name(self):
    pass

firstName = models.CharField(max_length=300)
middleName = models.CharField(max_length=300, blank=True)
lastName = models.CharField(max_length=300, blank=True)
username = models.CharField(unique=True, max_length=50)
businessName = models.CharField(max_length=500, default=None)
mobileNumber = models.CharField(max_length=20)
contactNumber = models.CharField(max_length=20)
addressLine1 = models.CharField(max_length=300)
addressLine2 = models.CharField(max_length=300)
city = models.CharField(max_length=300)
state = models.CharField(max_length=300)
role = models.CharField(max_length=20)
email_id = models.CharField(max_length=300, unique=True)
aadharNumber = models.BigIntegerField(default=0)
panNumber = models.CharField(max_length=20, default=None)
registrationDate = models.BigIntegerField(default=0)
bankDetail = models.ManyToManyField('BankDetail', related_name="bankDetail")
dateCreated = models.DateTimeField(auto_now_add=True)
dateModified = models.DateTimeField(auto_now=True)
objects = AccountManager()

USERNAME_FIELD = 'email_id'
REQUIRED_FIELDS = ['username']

我正在关注此博客https://afropolymath.svbtle.com/authentication-using-django-rest-framework中的示例以实现用户身份验证。

运行makemigrations时出现以下错误我确实在StackOverflow上看了几个解决方案，但那些似乎并没有解决我的问题。

有人可以帮助/指导我如何摆脱此错误并继续成功迁移。我一直坚持这个问题几个小时，没有解决方案。

提前致谢！

Answer 1

删除您的迁移。 然后运行makemigrations命令。
