django django-models

Django 事务模块对象没有原子属性,django,django-models,Django,Django Models,我想不出来。我一直得到一个“module”对象在事务对象上没有属性“atomic”。我不知道为什么它会自动破裂。我不记得了，但我可能已经更新了django的服务器版本 from django.db import transaction @receiver(post_save, sender=User) def saveUserAndInfo(sender, instance, **kwargs): user = instance try: with transa

@receiver(post_save, sender=User)
def saveUserAndInfo(sender, instance, **kwargs):
