Database_courseDesign 2 | bookshop system 3 | ## settings 4 | pycharm2020、MySQL、PyqtDesigner、python3.8 5 | ## attention 6 | 1.databasecoursedesign是没有UI界面的书店管理系统，可直接下载运行，当然前提是有相关数据库 7 | 8 | ~~2.路径pyqt/bookshop是有UI界面的书店管理系统，暂时还在开发中（2020/7/11）~~ 9 | 2.UI界面完成设计（2020/7/19） 10 | 3.后续完善和异常处理就要看心情了 11 | 12 | 13 | lastupdate 2020/12/14 14 | 在csdn上有很多小伙伴跟我进行了一些讨论，也指出了我代码中的一些不足之处，都进行了修改 15 | 现在再回头看看发现自己写的代码~~惨不忍睹~~，没有一点规范和良好的命名规范，这也导致了一些小伙伴的苦恼 16 | 17 | 18 | 首先是程序运行:从LoginUI.py运行，然后输入用户名和密码并且选择相应的操作来进行 19 | 管理员还是一般用户的操作，然后登陆到界面进行操作。 20 | 21 | 常见bug及修复 22 | 1. 无法运行程序 23 | 解决:程序目录下要有相应的用户存储文件，分别为admin.txt和user.txt 24 | 25 | 2. 进行用户操作(像查询书籍等等)就卡死 26 | 解决:在pycharm中(目前只有pycharm出现此问题)配置数据库连接，先进行连接再运行程序 27 | 28 | 3. 无法对书籍进行操作 29 | 解决:在ER设计时，可以想象有个全国图书库里面放着所有正版书籍，书店里面也许没有一些书，但是有的书籍必须在图书库里面可以 30 | 索引到，所以**想进行书籍操作(特别是购入书籍)就必须确保要操作的书籍在图书库中，也就是说要先进行添加书籍信息这个按钮的操作** 31 | 32 | 4. **必须要修改的部分** 33 | ```python 34 | self.db = connect(host='localhost', port=3306, charset='utf8', database='MySQL', password='zyh20000205', 35 | user='root') 36 | ``` 37 | 要将其中参数改为自己数据库参数，这里当初没有进行工具类的创建，现在知道了也懒得搞了 38 | 39 | 40 | -------------------------------------------------------------------------------- /UI image: -------------------------------------------------------------------------------- 1 | 2 | -------------------------------------------------------------------------------- /code/DatabaseCourseDesign.py: -------------------------------------------------------------------------------- 1 | #
