如何在创建用户后立即将该用户与django模型链接起来？

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

@receiver(post_save, sender=User)
def link_user_to_model(sender, instance, created, **kwargs):
    if created:
        # 在这里执行与模型链接的操作
        # 例如，创建一个与用户关联的模型实例
        # 或者更新现有模型实例的用户字段

from myapp.models import MyModel

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

from django.apps import AppConfig

class MyAppConfig(AppConfig):
    default_auto_field = 'django.db.models.BigAutoField'
    name = 'myapp'

    def ready(self):
        import myapp.signals  # 导入信号处理函数
