私はUserdjangoを拡張していますが、電話番号を追加する必要があることに気づきませんでした。makemigrations migrate以下のモデルを作成したとき、AppUser を作成する前に忘れていました。そのため、通常どおり AppUser/User コンボを作成しましたが、データベースの準備が整う前でした。デフォルトを指定するように求められますが、整数として 1 を使用できないため、文字列 '1' を指定しました
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
今、私は触れることができませんUserまたはAppUser:
In [4]: appusers = AppUser.objects.all()
In [5]: for user in appusers:

データベース全体を削除して再作成せずに、この汚物を修復できますか? ありがとうございました
