消费系统平账思路与实现
初入python，结合实际需求做一些简单的功能，还望大佬们斧正！先行谢过{:1_893:}！还有一些想优化和加强的功能会慢慢学着做出来；比如QT界面加载EXCEL文件，从配置文件读取数据库配置参数，用pyinstaller打包便于移植等。

excel格式：join_id emp_id card_id money
思路：差额为负值，进行数据库操作：充值；
insert into mealrecords() values();涉及emp_id，card_id，join_id，cardindex,times_money
falg（128：现金充值，4：出纳机充值）,temp_time,sign_time,clock_id,type(0：考勤，1，门禁，2，考勤门禁，3，消费)
差额为正值：进行数据库操作：消费,差额为负值：进行数据库操作：充值
最终的目的是将账面金额做平

看起来不错的样子棒棒哒加油 这个有用，希望后面有成品 这个是做什么用的？ 谢谢分享！ 加油把它完善一下 zz1181 发表于 2022-7-5 06:51
这个是做什么用的？
消费系统做平账的 谢谢分享，一种思路
