即使在回滚后，插入到原子事务中的数据仍然存在

Question

我正在尝试在 django 中实现这个原子事务，并且正在关注文档中的 this example。但是发现尽管回滚，更改仍然存在。我已经搜索了类似的问题，最常见的原因似乎是在原子块内捕获完整性错误，但我没有这样做。 以下是我的 Django 代码：

def get_lead_alert_data(params):
    with transaction.atomic():
        with acquire_lead_lock():
            caller = params['caller']
            via = params['via']
            called = params['called']
            leadphone = LeadsPhone.objects.filter(phone_number=caller, brokerage__isnull=True).first()
            if leadphone:
                lead_id = leadphone.lead_id
            else:
                lead_id = create_lead_from_inbound_call(caller, called)
        created, requirement = get_or_create_requirement_from_inbound_call(via, lead_id)
        picking_agent = Users.objects.get(phone_mobile=called)
        if created:
            RequirementAssignment.objects.create(requirement=requirement, agent=picking_agent)
            assigned_to = picking_agent.user_name
        else:
            assigned_requirement = RequirementAssignment.objects.filter(brokerage__active=True,
                                                                        requirement=requirement).first() #There will be only one such requirement
            if not assigned_requirement.agent:
                assigned_requirement.agent = picking_agent
                assigned_requirement.save()
            assigned_to = assigned_requirement.agent.user_name if assigned_requirement else 'nobody'
    return {'lead_id': lead_id, 'assigned_to': assigned_to, 'picking_by': picking_agent.user_name}

我还检查了 mysql 中的生成日志，它确实在调用回滚，但更改仍然存在。

哦，我查看了 mysql 文档。如果有任何锁定的表，看起来像解锁表implicitly causes a commit，在我的情况下。必须找到解决方法。
