在各学校的教学过程中,学生的作业管理是一项非常重要的事情。随着计算机多媒体技术的发展和网络的普及,“基于网络的学习模式”正悄无声息的改变着传统的教室学习模式,“基于网络的教学平台”的研究和设计也成为教育技术领域的热点课题。采用当前流行的B/S模式以及3层架构的设计思想通过Python技术来开发此系统的目的是建立一个配合网络环境的可以师生互动的电子作业提交与反馈的平台,这样可以有效地解决作业管理混乱的局面。本系统设计了3种角色:管理员,学生和教师。系统主要包括个人中心、学院管理、专业管理、班级管理、学生管理、教师管理、课程信息管理、作业布置管理、作业提交管理、作业批改管理等功能模块。
功能介绍
为了更好的去理清本系统整体思路,对该系统以结构图的形式表达出来,设计实现该学生作业管理系统的功能结构图如下所示:
执行下面的命令来创建一个新的 Django 项目:
django-admin startproject myproject
命令行工具django-admin会在安装Django的时候一起自动安装好。
执行了上面的命令以后,系统会为Django项目生成基础文件夹结构。
现在,我们的myproject目录结构如下所示:
myproject/ <-- 高级别的文件夹
|-- myproject/ <-- Django项目文件夹
| |-- myproject/
| | |-- init.py
| | |-- settings.py
| | |-- urls.py
| | |-- wsgi.py
| ±- manage.py
±- venv/ <-- 虚拟环境文件夹
