第二篇：BBS首页搭建、个人站点及侧边筛选栏

一、首页搭建

1、动态显示个人名称

需要实现效果如下所示。

登录之后显示。

html代码如下。

<!--判断用户是否登录-->
{% if request.user.is_authenticated %}
<li><a href="#">{{ request.user.username }}</a></li>
<li class="dropdown">
    <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">更多操作 <span class="caret"></span></a>
    <ul class="dropdown-menu">
        <li><a href="#">修改密码</a></li>
        <li><a href="#">修改头像</a></li>
        <li><a href="#">后台管理</a></li>
        <li role="separator" class="divider"></li>
        <li><a href="{% url ‘logout‘ %}">退出登录</a></li>
    </ul>
</li>
<!--用户没有登录-->
{% else %}
<li><a href="{% url ‘register‘ %}">注册</a></li>
<li><a href="{% url ‘login‘ %}">登录</a></li>
{% endif %}

2、admin后台管理

django给提供了一个可视化的界面，用来方便对模型表进行数据的增删改查。

如果想要使用amdin后台管理操作模型表，那么就需要先注册模型表告诉admin你需要操作哪些表。

方式如下。

"""去应用下的admin.py中注册你的模型表"""
from django.contrib import admin
from app01 import models
# Register your models here.

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

如此一来，我们可以在admin后台管理中操作，数据库表，使用超级用户进行登录。

针对这个数据库表，我们需要先从文章表入手，添加分类和标签，之后操作Article2tags表，最后记得要将用户表和个人站点表进行绑定。

我们可以将表名变成中文的形式，只需要在models.py中的表类中添加，效果如下。

代码如下。

class UserInfo(AbstractUser):
    # 手机号
    """
        null=True   数据库该字段可以为空
        blank=True  admin后台管理该字段可以为空
    """
    phone = models.BigIntegerField(verbose_name=‘手机号‘, null=True, blank=True)
    # 头像
    """给avatar字段传文件对象 该文件会自动存储到avatar文件下 然后avatar字段只保存文件路径avatar/default.png"""
    avatar = models.FileField(verbose_name=‘头像‘, upload_to=‘avatar/‘, default=‘avatar/default.png‘)
    # 创建时间
    create_time = models.DateField(verbose_name=‘创建时间‘, auto_now_add=True)
    # 一对一个人站点表
    blog = models.OneToOneField(to=‘Blog‘, null=True)

    # 修改admin后台管理中的表名
    class Meta:
        verbose_name_plural = ‘用户表‘
        verbose_name = ‘用户表‘  # 末尾还是会自动加s
    # 显示对象时，直接显示对象的username
    def __str__(self):
        return self.username

3、用户头像显示

效果如下。

"""
1 网址所使用的静态文件默认放在static文件夹下
2 用户上传的静态文件也应该单独放在某个文件夹下
"""

media配置:该配置可以让用户上传的所有文件都固定存放在某一个指定的文件夹下
配置方式 settings.py文件中
# 配置用户上传的文件存储位置
MEDIA_ROOT = os.path.join(BASE_DIR, ‘media‘)


当然，如果需要显示头像，还需要开设后端指定文件夹资源
在urls.py中

# 导入关于文件上传配置路径模块
from django.views.static import serve
from BBS import settings

urlpatterns = [
 	...
    # 暴露后端指定文件夹资源 【一种：static，一种便是如此配置】
    url(r‘^media/(?P<path>.*)‘, serve, {‘document_root‘: settings.MEDIA_ROOT}),
    ...
]

4、修改密码

效果如下。

代码如下。

"""login.html"""

首页效果如下。

二、个人站点和侧边栏筛选功能

"""补充"""
# 每个用户都可以通过暴露出来的media有自己的站点样式
<link rel="stylesheet" href="/media/css/{{ blog.site_theme }}/">

"""日期归档相关"""
django官网提供的一个orm语法
from django.db.models.functions import TruncMonth

Sales.objects.annotate(month=TruncMonth(‘timestamp‘))  # Truncate to month and add to select list
.values(‘month‘)  # Group By month
.annotate(c=Count(‘id‘))  # Select the count of the grouping
.values(‘month‘, ‘c‘)  # (might be redundant, haven‘t tested) select month and count

时区问题报错
TIME_ZONE = ‘Asia/Shanghai‘
USE_TZ = True


"""图片防盗链"""
# 如何避免别的网站直接通过本网站的url访问本网站资源
# 简单的防盗
	我可以做到请求来的时候先看看当前请求是从哪个网站过来的
  如果是本网站那么正常访问
  如果是其他网站直接拒绝
  	请求头里面有一个专门记录请求来自于哪个网址的参数
    	Referer: http://127.0.0.1:8000/xxx/
# 如何避免
1.要么修改请求头referer
2.直接写爬虫把对方网址的所有资源直接下载到我们自己的服务器上

如何实现这样的功能呢？
