问在syncdb之后指示Django运行自定义SQL的最佳方法是什么？

EN

from django.db.models.signals import post_syncdb
from django.db import connection

# Apply schema changes not defined by Django. Set a module-level
# flag to guard against multiple invocations of syncdb_handler()

def syncdb_handler(**kwargs):
    if getattr(connection, 'syncdb_called', None):
        return
    connection.syncdb_called = True
    cursor = connection.cursor()
    cursor.execute(open('/path/to/schema.sql')).read())

post_syncdb.connect(syncdb_handler)
