如何在使用Django-admin时实时同步postgres数据库和neo4j？

from django.db.models.signals import post_save, post_delete
from django.dispatch import receiver
from neo4j import GraphDatabase

@receiver(post_save, sender=YourModel)  # 替换YourModel为你的模型名称
def sync_postgresql_to_neo4j(sender, instance, **kwargs):
    # 在这里编写同步逻辑，将PostgreSQL中的数据同步到Neo4j

@receiver(post_delete, sender=YourModel)  # 替换YourModel为你的模型名称
def delete_from_neo4j(sender, instance, **kwargs):
    # 在这里编写删除逻辑，从Neo4j中删除对应的数据

uri = "bolt://localhost:7687"  # Neo4j数据库的连接地址
driver = GraphDatabase.driver(uri)

@receiver(post_save, sender=YourModel)
def sync_postgresql_to_neo4j(sender, instance, **kwargs):
    with driver.session() as session:
        # 将PostgreSQL中的数据同步到Neo4j
        query = """
            // 编写你的Cypher查询语句，将PostgreSQL数据同步到Neo4j
        """
        session.run(query)

@receiver(post_delete, sender=YourModel)
def delete_from_neo4j(sender, instance, **kwargs):
    with driver.session() as session:
        # 从Neo4j中删除对应的数据
        query = """
            // 编写你的Cypher查询语句，从Neo4j中删除对应的数据
        """
        session.run(query)

from django.apps import AppConfig

class YourAppConfig(AppConfig):
    name = 'your_app_name'  # 替换your_app_name为你的应用名称

    def ready(self):
        import your_app_name.signals  # 替换your_app_name为你的应用名称
