Create a Profile class in models and add fields. User forms a OneToOne relationship with User and cascade deletion

on_delete=models.CASCADE

from django.dispatch import receiverfrom django.db.models.signals import post_save

Decorator Decoration function, the signal is triggered when the User is created, and the user field of the Profile is automatically created and associated; the signal is triggered when the User is saved, and the Profile is automatically saved

Source code

from django.db import models
from django.contrib.auth.models import User
#信号
from django.db.models.signals import post_save,post_init
from django.dispatch import receiver
class Profile(models.Model):
    user = models.OneToOneField(User,on_delete=models.CASCADE)
    birth = models.DateField(null=True,blank=True)
    def __str__(self):
        return self.user.username
    class Meta:
        db_table = 'profile'
@receiver(post_save,sender=User)
def create_user_profile(sender,instance,created,**kwargs):
    print('创建User')
    if created:
        Profile.objects.create(user=instance)
@receiver(post_save,sender=User)
def save_user_profile(sender,instance,**kwargs):
    print('保存User')
