我是django的新手,正在学习如何使用以下站点扩展用户模型: https://simpleisbetterthancomplex.com/tutorial/2016/07/22/how-to-extend-django-user-model.html
我对以下模型有疑问:
from django.db import models
from django.contrib.auth.models import User
from django.db.models.signals import post_save
from django.dispatch import receiver
class Profile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
bio = models.TextField(max_length=500, blank=True)
location = models.CharField(max_length=30, blank=True)
birth_date = models.DateField(null=True, blank=True)
@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()
此行的工作原理:
Profile.objects.create(user=instance)
我知道创建用户后将调用post_save,但是我不明白如何使用以下行来存储其他字段。
Profile.objects.create(user=instance)
