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。
