1、项目介绍

  随着中国社会经济的快速发展，民众的生活质量不断提高，网络一直在改变这人们的生活，包括衣食住行方便都在被网络所渗透。现代生活中，人们为了缓解生活中的精神疲惫，常常选择通过美食来放松身心。随着各地美食的普及程度的提高，意味着人们的生活水平质量不断的在提高。美食不仅会带给我们视觉的享受，同时还会带来身心的一个满足。以往得知好吃的美食大多都是通过周围朋友的口述评价等，这样得知的形式过于狭义，不能代表大多数人的一个评价与口味。另外，由于每一个人的口味差异的不同，大家无法得知其他人对美食的评价。此时就需要通过一个媒介收集大家不同感受并公开于众，有了更多的声音，才能更好的去对美食做一个系统的评论与推荐。

2、核心功能模块

  基于Python的美食推荐系统，选用B/S模式，应用django技术， MySQL为后台数据库。系统主要包括首页，个人中心，美景、美食推荐、地图、评论、收藏、搜索、查看美食视频、查看美景美食资讯新闻、发帖组团同游、美食分类管理、用户管理，分享管理等功能模块。

  基于Python的美食推荐系统的设计与实现的设计思想如下：
  1、操作简单方便、系统界面安全良好：简单明了的页面布局，方便查询景点中的美食相关信息。
  2、即时可见：对美食、景点信息的处理将立马在搜索中可以查询到，从而实现“即时搜素、即时推荐”的系统功能。
