Library-Management-System 2 | 3 | 图书管理系统，学弟学妹们记得star和fork哦 4 | 5 | 功能详见 说明.pdf（其实就是我当时的实验报告，差不多可以直接用） 6 | 7 | ## 注意事项 8 | 9 | 没想到还有挺多人看的，简单修复了一下错误，基本功能应该是没啥问题，学弟学妹们可以自行添加/删除功能。 10 | 11 | 2024.5.4号更新，4个issues都解决了，现在基本功能应该没啥问题了。 12 | 13 | 在创建数据库的时候，默认加入了一个管理员，用户名/密码为admin/123456。后面新注册的都是学生用户，密码在数据表里面存储的都是加密后的数据。 14 | 15 | 数据表里面本来是有挺多条数据的，找不到了。。。大家自己添加几条信息吧，也可以看我上传的视频，看看效果。 16 | 17 | ## 使用前提 18 | 19 | 保证已安装mysql数据库。 20 | 21 | 我记得这门课应该有历代祖传的mysql5.6+navicat。按照提示安装即可。 22 | 23 | ![alt text](image/image.png) 24 | 25 | ## 使用方法 26 | 27 | 1.首先需要单独执行createDB.py来创建数据库。（python环境要有pymsql包） 28 | 29 | 2.创建好之后执行main.py即可运行。（python环境要有pyqt5） 30 | 31 | ## 代码文件说明 32 | 33 | 1. icon文件夹：存放一些小图标。 34 | 2. image文件夹：存放一些图片。 35 | 3. createDB.py：创建数据库的文件，运行一次把这些表创建就行。会创建一个名为library的数据库，里面有6张表。 36 | 4. main.py：程序执行主文件。 37 | 5. login.py:登录前端界面代码。 38 | 6. signup.py：注册前端界面代码。 39 | 7. administrator.py：管理员前端界面代码。 40 | 8. book_information.py：管理员前端界面中编辑书本信息的界面代码。 41 | 9. student.py：学生前端界面代码。 42 | 10. student_information.py：学生前端界面中学生信息界面代码。 43 | 11. func.py：所有的后端处理函数。 44 | -------------------------------------------------------------------------------- /administrator.py: -------------------------------------------------------------------------------- 1 | import sys 2 | import time 3 | import os 4 | from PyQt5.QtWidgets import (QApplication, QWidget, QGridLayout, QGroupBox, 5 | QToolButton, QSplitter, QVBoxLayout, QHBoxLayout, 6 | QLabel, QTableWidget, QTableWidgetItem, QAbstractItemView, 7 | QLineEdit, QFileDialog, QMessageBox, QComboBox) 8 | from PyQt5.QtGui import QIcon, QFont 9 | from PyQt5.QtCore import Qt, QSize 10 | import func 11 | import student_information 12 | import book_information 13 | 14 | 15 | class AdministratorPage(QWidget): 16 | def __init__(self, info): 17 | super().__init__() 18 | self.info = info 19 | self.focus = 0 20 | self.initUI() 21 | 22 | def initUI(self): 23 | #
