运行 "createsuperuser" 时 SQLite3 完整性错误

Question

我正在尝试通过 OneToOneField.

链接到它来扩展默认的 Django User 模型

我成功迁移了更改并在 admin.py 中注册了我的 Profile 模型，但是，当我尝试运行命令 python manage.py createsuperuser 并填写信息我得到一个 完整性错误 。

django.db.utils.IntegrityError: NOT NULL constraint failed: accounts_profile.date_of_birth

我知道问题出在哪里。我有一个名为 date_of_birth 的字段，这是必需的，我不能将其留空，这会引发异常。

我想要一个简单的解决方案，但想不出一个，而且我不想在所有必填字段中添加一堆 blank=True 片段。

这是我的代码。

models.py

    # - [ CHOICES ] - #

signals.py

from django.db.models.signals import post_save
from django.contrib.auth.models import User
from django.dispatch import receiver

from .models import Profile


@receiver(post_save, sender=User)
def create_user_profile(sender, instance, created, **kwargs):
    if created:
        Profile.objects.create(user=instance)


@receiver(post_save, sender=User)
def save_user_profile(sender, instance, **kwargs):
    instance.profile.save()

Answer 1

您需要删除迁移文件并再次运行 python manage.py makemigrations 命令。当它提示一次性默认值时，您可以使用 timezone.now，以填充数据库中预先存在的行。

Answer 2

我已经通过为 date_of_birth 字段提供默认值解决了这个问题。
