效果
实现效果图如下，根据过滤条件查询相关信息。
知识点
1.配置URL，在路由中使用正则表达式
2.过滤查询
代码
setting.py
1 from django.contrib import admin 2 from django.urls import path,re_path,include 3 from app01 import views 4 urlpatterns = [ 5 path('admin/', admin.site.urls), 6 path('article-(d+)-(d+).html', views.article), 7 re_path(r'article-(?P<article_type_id>d+)-(?P<category_id>d+).html', views.article,name="article"), #正则过滤 8 ]
