我正在尝试弄清楚如何扩展 Django 用户模型以向用户添加信息。我似乎无法让它发挥作用。我究竟做错了什么？
我可以在扩展的同一模型中使用外键吗？如何创建超级用户，还是必须通过手动创建python manage.py shell?
到目前为止，这是我的代码：
class PersonModel(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
firstName = models.CharField(max_length=50)
lastName = models.CharField(max_length=50)
company = models.ForeignKey(CompanyModel, on_delete=models.CASCADE, null=True)
phone = models.ForeignKey(PhoneModel, on_delete=models.CASCADE, null=True)
email = models.EmailField(blank=True)
def __str__(self):
return '%s %s - %s - %s, %s' % (self.firstName, self.lastName,
self.company, self.phone, self.email
)
class Meta:
ordering = ['firstName']
verbose_name = "Customer Contact Information"
#verbose_name_plural = "Contacts"
@receiver(post_save, sender=User)
def create_user_profile(sender, instance, created, **kwargs):
if created:
PersonModel.objects.create(user=instance)
@receiver(post_save, sender=User)
def save_user_profile(sender, instance, **kwargs):
instance.profile.save()
更新（最终）：
在 raratiru 的帮助下，我基本上能够完成他分享的脚本。由于我的外键要求，我仍然很难创建超级用户。

为了避免外键问题，最简单的解决方案是在创建超级用户之前删除 null=False 要求 - 之后分配公司和电话 - 然后将 null 设置回 false。
