Python-django在线考试系统搭建[前端+后端 ]

一:项目目标:

1,制作一个学生端:可以登录,在线考试,查看成绩.教师端:可以进行组卷,分析试卷,查看学生成绩.管理员端可以进行数据修改.

2,主要运用的技术:前端(bootstrap+jQuery+html+js+css)后端(django2.0+Python)数据库(MySQL).

3,使用流程:教师组卷--------学生接收试卷--------学生在线考试------------考试结束----------系统分析学生成绩----------教师查看成绩.

4,不足点<系统没有设计防作弊的系统>

二:项目过程:

1,分析表与表之间的关系如下图:

2,分析完表之后在合适的目录下创建项目还是老三样(创建项目这里不做说明,可以搜索自学堂查看django相关教程)

3,配置stting文件(主要激活应用,添加APP,改汉语,修改数据库)
