首页文章列表

登陆超级管理员录入数据

先在admin.py中将表注册后 可以看到表名

from django.contrib import admin
from .models import *

# Register your models here.
admin.site.register(UserInfo)
admin.site.register(Blog)
admin.site.register(Tag)
admin.site.register(Classify)
admin.site.register(Article)
admin.site.register(UpAndDown)
admin.site.register(Comment)

注意:显示表名需在models.py中创建表时添加一个Meta类

class Meta:
    verbose_name_plural = '个人站点表'

定义字段时添加属性verbose_name在添加数据时显示
在创建表时定义双下str方法可以自定义显示的创建对象名字

def __str__(self):
    return self.title

开启media访问

Django中的media文件夹一般用来存放文件，图片等不重要的数据，想在前端通过路径访问media中的数据，是不可以的，需要开启media访问

在settings.py中添加

MEDIA_ROOT = os.path.join(BASEDIR, 'media')

在urls中添加

from django.views.static import serve
from django.conf import settings

path('media/<path:path>', serve, {'document_root':settings.MEDIA_ROOT})

注意：static文件夹已经默认开启，可以从浏览器进行访问，所以static和media文件夹下不能放重要文件

图片防盗链

有的网站有上传图片功能，可以上传到该网站，然后再自己的网站使用，这样就不会消耗自己的带宽

图片防盗链就是抑制这种行为，本质原理是：浏览器发送http请求，请求头中会携带referer参数，是一个url地址，表示上一次访问的地址，图片防盗链可以跟据这个地址判断是不是自己的网址发的请求，如果不是直接拒绝响应。

首页文章渲染

views.py
后端返回所有文章

def index(request):
    article_query_set = Article.objects.all()
    return render(request, 'index.html', context={'article_query_set': article_query_set})

index.html

<div class="article" style="margin-top: 20px">
    {% for foo in article_query_set %}
        <div style="margin-top: 20px">
            <h4 class="media-heading"><a href="">{{ foo.title }}</a></h4>
            <hr>
            <div class="media">
                <div class="media-left">
                    <a href="#">
                        <img class="media-object" src="/media/{{ foo.blog.userinfo.icon }}" alt="..."
                             width="60px" height="60px">

                <div class="media-body">
                    <h4 class="media-heading">{{ foo.desc }}</h4>
                </div>
            </div>

            <div class="" style="margin-top: 20px">
                <a href="{{ foo.blog.userinfo.username }}"><span
                        style="padding: 10px;font-size: 13px">{{ foo.blog.userinfo.username }}</span></a>
                <span style="padding: 5px;font-size: 13px">{{ foo.create_time|date:'Y-m-d H:s' }}</span>
                <span style="padding: 5px;font-size: 13px"><i class="fa fa-thumbs-o-up"

                <span style="padding: 10px;font-size: 13px"><i class="fa fa-commenting"
                                                               aria-hidden="true"></i>{{ foo.comment_num }}</span>
            </div>

个人站点页面搭建

路由配置

当点击用户名 则跳转到用户对应的站点（如果存在）不存在就返回404界面

# 站点匹配 必须放最后
path('<str:name>/', views.site),

后端

def site(request, name, **kwargs):
    user = UserInfo.objects.filter(username=name).first()
    if not user:
        return render(request, 'error.html')
    article_set = user.blog.article_set.all()
    return render(request, 'site.html', locals())

404界面

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>404</title>
</head>
<body>
