摘  要

本系统的目标是利用基于python的开源Web框架Django，采用MTV (Model-View-Template) 的框架模式实现教育培训网课系统。遵循网络教学的规则对课程进行设计，并提供大量的教学资源和完善的教学服务，使学生获得个性化、更丰富的在线学习方式，提高学习的效率和学习质量.本系统中用户可分为学员、教员和系统管理员，不同用户类型都有不同的操作权限，登录后的界面也不尽相同。因此，在系统登录时，后台子系统会根据数据库中比对用户信息和类型，将判定结果回馈给系统，并把相应的操作界面通过前台子系统呈现给用户，用户还可以在后台个人中心对个人信息进行修改。该模块主要用于教员对课程进行管理，可以进行课程视频上传，还可以查看已经上传的课程列表,对上传后的视频进行编辑修改，还可以搜索已经上传的课程资源.该模块可以用于对自己看过的课程资源进行评论，增强互动,有利于企业从众多课程中选取优质课程作为精品课程。利用开源的python开发的Web框架Django来构建Web框架，并完成前后端数据交互，最终实现课程资讯的展示、浏览、购买、后台实现数据的管理、存储、订单的付费等整个系统的基本功能。

基于Django框架的教育网课系统的设计与实现采用文献法和软件开发方法以及原型法（查找并借鉴别人已经实现的Django框架系统平台。研究技术采用的后台架构模式是Django的MTV设计模式。选择的开发工具和服务器几乎都是开源免费，因此经济上是可行的。根据市场需求分析，这个项目是有市场需求的，因此很有市场前景。

Abstract

The goal of this system is to use the open source web framework django based on python and adopt the framework model of mtv (model-view-template) to realize the education training web course system. Follow the rules of online teaching to design the course, and provide a large number of teaching resources and perfect teaching services, so that students can obtain personalized, more abundant online learning methods, and improve the efficiency and quality of learning. The users in this system can be divided into trainees, teachers and system administrators, different user types have different operation permissions, and the interface after login is different. Therefore, in the department  When the system is registered, the background subsystem will give back the decision result to the system according to the comparison of user information and type in the database, and present the corresponding operation interface to the user through the front subsystem, and the user can also modify the personal information in the background personal center. This module is mainly used for the teacher to manage the course, can carry on the course video upload, can also view the list of courses that have been uploaded, edit and modify the video after uploading, and can also search for the course resources that have been uploaded. This module can be used to comment on the curriculum resources that I have seen, enhance the interaction, and help enterprises to select quality courses from many courses as a good course  Fine courses. the web framework developed by open source python, django, is used to construct the web framework, and the front and rear end data interaction is completed. finally, the basic functions of the whole system, such as presentation of course information, browsing, purchase, background implementation of data management, storage, order payment and so on, are realized.

The design and implementation of the education network course system based on the Django framework adopt the literature method and the software development method as well as the prototype method (find and draw lessons from the Django framework system platform that others have already implemented. The background architecture pattern used in the research technology is the MTV design pattern of Django. Selected development tools and servers are almost all open source free and therefore economically viable. According to the analysis of market demand, this project has market demand, so it has market prospects.
