有没有一种方法可以在Django中创建记录时自动创建页面(和段)

from django.db.models.signals import post_save
from django.dispatch import receiver
from django.contrib.auth.models import User
from django.contrib.sites.models import Site
from django.contrib.flatpages.models import FlatPage

@receiver(post_save, sender=User)
def create_flatpage(sender, instance, created, **kwargs):
    if created:
        # 创建页面
        page = FlatPage.objects.create(
            url=f'/{instance.username}/',
            title=f'{instance.username}的页面',
            content='这是我的页面内容。',
            enable_comments=True,
        )
        
        # 创建段
        section = page.content_set.create(
            title='欢迎',
            content='欢迎访问我的页面。',
        )

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

# ...

post_save.connect(create_flatpage, sender=User)
