重写base.html定义的接口content
实现“今日必抢”的商品热销功能，该功能共分为2页，每页自动进行轮播展示
{% url ‘commodity:detail’ c.id %}是使用商品的主键字段id生成对应的商品详细页的路由地址，当单击商品即可查看商品详细页。
{{ c.img.url }}代表当前遍历对象的字段img
{{ c.name }}获取当前遍历对象的字段name
{{ c.discount|floatformat:‘2’ }}获取当前遍历对象的字段discount
{{ c.price|floatformat:‘2’ }}获取当前遍历对象的字段price
实现某分类的商品热销功能，分别为“宝宝服饰”、“奶粉辅食”和“宝宝用品”
重写base.html定义的接口footer和script
commodity-urls.py

from django.contrib import adminfrom django.urls import path, include, re_pathfrom django.views.static import servefrom django.conf import settingsurlpatterns = [ path("admin/", admin.site.urls), path("", include(("index.urls","index"),namespace="index")), path("commodity", include(("commodity.urls","commodity"),namespace="commodity")), path("shopper", include(("shopper.urls","shopper"),namespace="shopper")), re_path("media/(?P.*)" , serve, {"document_root":settings.MEDIA_ROOT}, name="media"),]
re_path("media/(?P.*)", serve, {"document_root":settings.MEDIA_ROOT}, name="media"),
配置媒体资源的路由信息
一定要配置否则无法加载媒体资源
运行Django 服务器
浏览器打开 http://127.0.0.1:8000/
