Django的事务开启两种方式

#第一种 导入模块
from django.db import transaction
with transaction.atomic():
    ...
    
#第二种 装饰器
@transaction.atomic
    def post(self,request):
            ...
            sid=transaction.savepoint()  #开启事务
            ...
            transaction.savepoint_rollback(sid)  # 回滚
            ...
            transaction.savepoint_commit(sid)  # 提交
