最近想学爬虫，但是呢，我想搭建一个网站来熟悉一下网页中的东西，我起初的想法是做一个个人博客网站，我django项目都创建了，我用了几天的时间来构思这个网站应该怎么做，正当我在构思的时候，我突然有了一个灵感，那就是我暑假放弃了的个人商城demo，于是我就用这个框架来做了我的个人商城网站。说这么多，主要是想解释我这个项目的命名为什么是my_blog了，而不是不是以shopping命名的项目了。好了，下面进入正题吧。
这里我先简单说一下这个网站能实现哪些功能，能够浏览商品，搜索商品，购买商品功能（没有付款接口，当然只是模拟付款），购物车功能，登录功能（没有用django自带的用户表，含验证登录与保持登录功能）。
我先说一下我做这个项目的版本：python3.6.3, django2.0.5用到的前端框架是bootstrap-3.3.7。这里我需要提一点，这个项目应该适合做过django项目的同学，最少也要使用django框架连接过数据库。不然做这个项目将会很吃力。
好了，我先上一下效果图吧。
商城首页：
点击导航栏中的‘男装’。
图片就贴到这里吧，不能都贴出来，不然就太垮了。我把项目的构架先贴出来
项目的第一步，一定是数据表，数据关系一定要先规划好，不然很有可能使项目做到一半需要大改，这样的话就非常伤脑筋了。这里我贴出models.py的代码。别忘了命令行python manage.py makemigrations , python mange.py migrate迁移数据库文件，与映射数据表到数据库。

将数据表注册到django后台代码，可以在django后台添加数据。

urls.py的配置。我由于想快速开发我的网站，我就没有将url include分开来写。
