BBS文章内容的搭建

一、文章的框架搭建

1、媒体对象列表

https://v3.bootcss.com/components/#btn-dropdowns

<ul class="media-list">
  <li class="media">
    <div class="media-left">
      <a href="#">
        <img class="media-object" src="..." alt="...">
      </a>
    </div>
    <div class="media-body">
      <h4 class="media-heading">Media heading</h4>
      ...
    </div>
  </li>
</ul>

2.前端页面

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <script src="https://cdn.bootcdn.net/ajax/libs/jquery/3.6.1/jquery.js"></script>
    <link rel="stylesheet" href="/static/bootstrap-3.4.1-dist/css/bootstrap.css">
    <script src="/static/bootstrap-3.4.1-dist/js/bootstrap.js"></script>
</head>
<body background="/static/img/img_2.png"
      style="background-repeat:no-repeat; background-attachment: fixed; background-size: 100% 100%">

二、Django后台添加和绑定数据

由于往数据库中直接加入数据太麻烦,所以我们要用Django自动的后台管理系统
因为我们之前创的用户密码的加盐是我们自己写的方法,所以这里即使把0改成1也不能登录admin后台,所以我们要createsuperuser手动创建一个
image
记一下密码吧
image
然后打开Django的admin后台管理,发现数据库中的表这里都是没有的,所以我们要进行导入
image
在admin文件里面操作
image

from django.contrib import admin

# Register your models here.

from app01 import models
admin.site.register(models.UserInfo)
admin.site.register(models.Blog)
admin.site.register(models.Tag)
admin.site.register(models.Category)
admin.site.register(models.Article)
admin.site.register(models.Article2Tag)
admin.site.register(models.UpAndDown)
admin.site.register(models.Comment)

刷新可见
image
如何把英文的表名改成中文的?只需在models的每个类下面加上:

  class Meta:
        verbose_name_plural = '文章表'
        # verbose_name = '文章表'  # 这个中文后面会加s

这里默认只会显示对象,所以别忘记去改__str__
image

   def __str__(self):
        return self.site_name

这里用户绑定站点出现的问题,需要在phone字节后面加上一个属性blank=True
image

    """
        null=True, 代表的是数据库中可以为空
        blank=True,代表的是django的后台页面上可以为空
    """

三、文章的真实数据导入前端(读取数据库文章表)

media文件的开放

配置文件中

# 只要配置了这句话,以后再上传图片的话,就会上传到这个文件夹下面去
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')

URL开设接口(/此时前端还是无法看到,要在路由添加一个接口/media/)

from django.views.static import serve
from django.conf import settings
# 如果你想访问media文件夹下的内容,必须开设一个接口对外访问(这里注意要正则匹配,否则图片找不到资源)
 re_path(r'^media/(?P<path>.*)$', serve, {'document_root': settings.MEDIA_ROOT}),

视图函数

@login_auth
def home(request):
    # 读取所有的文章的列表
    article_list = models.Article.objects.all()
    return render(request, 'home.html', locals())

html

    {#中间的内容#}
    <div class="col-md-7">
        <ul class="media-list">
            {% for article in article_list %}
                 <li class="media">
                <h4 class="media-heading"><a href="">{{ article.title }}</a></h4>
                <div class="media-left">
                    <a href="">
                        <img class="media-object" src="/media/{{ article.blog.userinfo.avatar }}" alt="..." style="    width: 70px;">
                    </a>
                </div>
                <div class="media-body">
                    {{ article.desc }}
                </div>
                <br>
                <div>
                    {# xiezhr 2023-05-10 08:04  1   0 121     #}
                    <span><a href="">{{ article.blog.userinfo.username }}</a></span>  &nbsp;  &nbsp;
                    <span><a href="">{{ article.create_time|date:'Y-m-d' }}</a></span>  &nbsp;  &nbsp;
                    <span><a href="">08:04</a></span>&nbsp;  &nbsp;
                    <span><span class="glyphicon glyphicon-thumbs-up"></span>({{ article.up_num }})</span>  &nbsp;  &nbsp;
                    <span><span class="glyphicon glyphicon-thumbs-down"></span>({{ article.down_num }})</span>  &nbsp;  &nbsp;
                    <span><span class="glyphicon glyphicon-comment"></span>({{ article.comment_num }})</span>  &nbsp;  &nbsp;
                </div>
            </li>
            {% endfor %}
            <hr>
        </ul>
    </div>
