4.保存csv功能
点击保存csv按钮，可下载当前显示课表的csv格式文档。
5.管理员登录界面
6.管理员后台界面
管理员通过后台可以对老师、学生、班级等数据表进行增删改查功能，同时管理员后台首页可以实时的对每个班级/老师的课程进行安排，还有简单的筛选搜索功能、导出csv功能、新增/删除/修改课表信息功能。
7.代码详解
-
数据库建模
根据需求分析，总共建立了老师表、班级表、学生表、教室表、课程总表
-
表之间的关系
学生表和班级表是一对多的关系，
课程表和老师表是一对多的关系，
课程表班级表是一对多的关系，
课程表教室表是一对多的关系。

后台管理
后台管理使用的Django的第三方ui库simpleui来美化后台界面，参数配置如下。
#settings.py
#后台logo
SIMPLEUI_LOGO=r'/static/favicon.ico'
#关闭simpleui广告
SIMPLEUI_HOME_INFO = False
#后台首页
SIMPLEUI_HOME_PAGE = '/root_index'
