我在django上展开User并且没有意识到我需要添加电话号码。当我在下面制作模型时，在创建AppUser之前忘了makemigrations migrate。所以我正常做了一个AppUser / User组合，但在db准备好之前。它要求我提供默认值，我提供了字符串＆＃39; 1＆＃39;因为它不会将1作为整数
from __future__ import unicode_literals
from django.db import models
from django.contrib.auth.models import User
from django.core.validators import RegexValidator
class AppUser(models.Model):
user = models.OneToOneField(User, primary_key=True, on_delete=models.CASCADE)
phone_regex = RegexValidator(regex=r'^\+?1?\d{9,15}$', message="Phone number must be entered in the format: '+999999999'. Up to 15 digits allowed.")
phone_number = models.CharField(validators=[phone_regex], max_length=16, blank=True) # validators should be a list
def __str__(self):
return self.first_name + " " + self.last_name + ": " + self.email
现在我无法触及User或AppUser：
In [4]: appusers = AppUser.objects.all()
In [5]: for user in appusers:
...: user.delete()
...:

我可以在不丢弃和重建整个数据库的情况下修复此污秽吗？谢谢
