python django超链接

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。
