【项目实战】基于Python、Django以及MySQL的学生选课系统（附完整源码）

1、项目说明

基于python+Django+Mysql的学生选课系统项目实战

项目需要安装pycharm专业版以及MySQL环境（环境搭建和破解可以看我的B站里的视频有讲解）

  • 首先需要创建数据库数据库名字叫做 db_course_selection
  • 运行sql导入数据或者也可以直接用命令生成（视频有讲解）
  • 需要安装一下下面的模块（如果运行提示有模块未安装，安装一下即可，命令同下，改一下模块名即可）

项目需要安装 Django、及其附带的其他一些模块

  • Django==3.2.17
  • PyMySQL==0.9.3

安装命令如下：

 

2、项目主要技术

  • python编程技术

  • django框架技术

  • mysql数据库技术

  • 前端技术

 

3、项目结构CourseSelectionSystem：

  • course 课程管理模块

  • CourseSelectionSystem 主模块 (项目的配置文件、主路由)

  • user 用户信息管理模块

  • static 静态文件文件夹（css,js）

  • templates 前端html文件

  • constats.py 项目常量配置文件

  • manage.py 程序的入口

 

4、项目主要功能

  • 用户登录注册

  • 课程展示

  • 学生选课、评课、评教

  • 教师发布课程、给学生打分，评价
