python django超链接

本文主要是介绍python django超链接,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!
之前用django框架打了一个简易的博客网站,现在说说怎么用django做超链接。
本文基于之前讲解的博客应用,如果只想学超链接请自行删减代码或评论提问。
首先,在templates文件夹下添加details.html文件:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>{{ data.title }}</title> </head> <body> <h2>{{ data.title }}</h2> <img style="width: 450px;height: 300px;" src="{{ data.img }}"> </body> </html>
然后,再添加menu.html文件:
<html lang="en"> <head> <meta charset="UTF-8"> <title>Carton</title> </head> <body> <ul> {% for item in data %} <li> <a href="/details/{{ item.id }}">{{ item.title }}</a> </li> {% endfor %} </ul> </body> </html>
切记,html文件不能有中文!!!不然UTF-8编码会出错,页面会显示UnicodeError。
然后就开始建立连接了:
先打开views.py;
from django.shortcuts import render,redirect,render_to_response from blog.models import BlogsPost # Create your views here. def blog_index(request): blog_list = BlogsPost.objects.all() return render(request,'index.html', {'blog_list': blog_list}) def blog_school(request): return redirect('https://www.dlmu.edu.cn/') def details_render(response, id): data = { "1": {"title": "one", 'img': 'http://photocdn.sohu.com/20140303/Img395937155.jpg'}, "2": {"title": "two", 'img': 'http://p4.so.qhmsg.com/sdr/400__/t01145220e19e14dd69.jpg'}, "3": {"title": "three", 'img': 'http://uploads.5068.com/allimg/1812/224-1Q21Q51239.jpg'}, "4": {"title": "four", 'img': 'http://www.chinaqw.com/zhwh/2016/09-06/U682P894T5D102134F42DT20160906113524.jpg'}, "5": {"title": "five", 'img': 'https://p1.ssl.qhmsg.com/t01409ee9dd99712d8c.jpg'} }.get(id) return render_to_response("details.html", locals()) def menu_list(request): data = [ {"id": 1, "title": "The Chinese dream"}, {"id": 2, "title": "Core socialist values"}, {"id": 3, "title": "Reform and opening up"}, {"id": 4, "title": "The Belt and Road"}, {"id": 5, "title": "Dalian Maritime University"} ] return render_to_response("menu.html", locals())
接下来添加URL:
打开urls.py:
from django.conf.urls import url from django.urls import path,re_path from django.contrib import admin from blog import views urlpatterns = [ url('admin/', admin.site.urls), url(r'^blog/$',views.blog_index,name='index'), url(r'^school/$',views.blog_school), path('menu_list/',views.menu_list), re_path(r'details/(?P<id>\d{1,2})',views.details_render), ]
这是运行程序,输入 http://127.0.0.1:8000/menu_list 即可打开超链接。
