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) 的框架模式实现在线教育平台。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框架的在线教育平台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 based on python to implement the online education platform Django，using the framework model of Model-View-Template. Follow the rules of network 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，improve the efficiency and quality of learning. Users in this system can be divided into trainees，instructors and system administrators，different user types have different operating rights，login interface is not the same. Therefore，in the system When recording，the background subsystem will compare the user information and type in the database，feedback the decision result to the system，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 teachers to manage the course，can upload the course video，can also view the list of courses that have been uploaded，edit and modify the uploaded video，and can also search for the course resources that have been uploaded. This module can be used to comment on the curriculum resources they have seen and enhance the interaction，which is helpful for enterprises to select high quality courses as high quality courses from many courses Courses. Using the Web framework Django developed by source python is used to construct the framework，and to complete the data interaction between the front and back，and finally to realize the basic functions of the whole system，such as the display，browsing，purchasing，background data management，storage，payment of orders and so on.

The design and implementation of online education platform based on Django framework adopts literature method and software development method as well as prototype method (find and draw lessons from others already realized Django framework system platform. The background architecture pattern adopted by the research technology is Django MTV design pattern. The choice of development tools and servers is almost open source free，so it is economically feasible. According to the market demand analysis，this project has the market demand，therefore has the market prospect very much.
