python 封装django中事务

from functools import wraps
from django.db import transaction


def my_transaction(func):
    @wraps(func)
    def wrap(*args, **kwargs):
        # 开启事务
        try:
            with transaction.atomic():
                save_point = transaction.savepoint()
                func(*args, **kwargs)
                # 提交事务 参数是上面定义的保存点
                transaction.savepoint_commit(save_point)
        except Exception as e:
            transaction.savepoint_rollback(save_point)
        return my_transaction

    return wrap

1.将my_transaction导入到view。之后在请求函数上进行装饰 @my_transaction
