项目编号：BS-Python-006
一，环境介绍
语言环境：Python3.7
数据库：Mysql: mysql5.7
开发工具：IDEA 或其它
开发技术：Django框架，前端使用Layui+html
二，项目简介
本项目基于Python语言开发实现，使用了Django WEB框架开发，前端使用Layui+HTML进行页面开发，提供了登录验证码和图形报表统计，以及数据导入导出的基本功能。
系统的用户角色可以灵活的自定义实现，目前设定的有管理员、班主任和普通用户等，可以根据需求自定义角色和权限，系统权限分为菜单级和按钮级，控制的十分细致，完全根据需要来控制对某些数据的增删改查操作，并根据需要给相应的用户授予相应的权限。
系统的主要功能模块包含：
用户管理：完成对用户信息的新增、查询和删除、导出等操作。
角色管理：完成对角色信息的新增、查询和编辑、删除、导出等操作。为角色授于不同的权限功能。
权限管理：完成对权限信息的新增、查询和删除、导出和启用等操作。
日志管理：主要对用户的操作日志进行查看和删除操作。
学校管理：完成对学校信息的新增、查询和删除操作。
年级管理：完成对年级信息的新增、查询和删除操作。
班级管理：完成对班级信息的新增、查询和删除操作。
课程管理：完成对课程信息的新增、查询和删除操作。
学生管理：完成对学生信息的新增、查询和删除操作，并可以进行批量导入和导出。
成绩录入：为每个学生进行成绩录入。
班级成绩：查询统计各学校各班级各学科的参考人数及各分数段的人数。
学生成绩：对所有学生的成绩信息进行管理和数据导入等操作。
数据统计：通过Echart图形报表完成相关数据统计。
个人资料修改：完成个人资料和密码的修改操作。
