项目介绍 在各学校的教学过程中,django过程管理系统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。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django过程管理系统的平台,这样可以有效地解决django过程管理系统混乱的局面。 本文首先介绍了django过程管理系统的发展背景与发展现状,然后遵循软件常规开发流程,首先针对系统选取适用的语言和开发平台,根据需求分析制定模块并设计数据库结构,再根据系统总体功能模块的设计绘制系统的功能模块图,流程图以及E-R图。然后,设计框架并根据设计的框架编写代码以实现系统的各个功能模块。最后,对初步完成的系统进行测试,主要是功能测试、单元测试和性能测试。测试结果表明,该系统能够实现所需的功能,运行状况尚可并无明显缺点。
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django过程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
