### 2.2 站点管理 ###

from django.contrib import admin
    
    # Register your models here.
    from blog import models
    
    admin.site.register(models.UserInfo)
    admin.site.register(models.Article)
    admin.site.register(models.Article2Tag)
    admin.site.register(models.ArticleUpDown)
    admin.site.register(models.Blog)
    admin.site.register(models.Category)
    admin.site.register(models.Comment)
    admin.site.register(models.Tag)

### 2.3 注册 ###

**核心代码**

1.form组件
    
    1.form组件
        class RegForm(forms.Form):pass
        局部钩子 全局钩子
    
    2.上传头像 avatar
        图像预览
            var reader = new FileReader();
        上传文件
            formdata = new FormData();
    
    3.用户文件配置
        avatar = models.FileField(upload_to='avatars/', default='avatars/default.png')
        MEDIA_ROOT = os.path.join(BASE_DIR, 'blog', 'media')
        MEDIA_URL = '/media/'
        re_path(r'media/(?P<path>.*)$',serve,{
        'document_root':settings.MEDIA_ROOT})

![在这里插入图片描述][watermark_type_ZHJvaWRzYW5zZmFsbGJhY2s_shadow_50_text_Q1NETiBAbWF0aG9yLXNpbm9y_size_20_color_FFFFFF_t_70_g_se_x_16 3]

### 2.4 登录 ###

1.验证码
        随机生成5个字符，0-9 a-z A-Z
    
        pip install pillow
        from PIL import Image, ImageDraw, ImageFont
            image = Image.new()
    
        在内存中生成图片直接返回
        from io import BytesIO
            f = BytesIO()
    
    2.request.session['valid_str'] = valid_str
        存在session中，为了之后登录，验证是否通过
    
    3.验证码点击刷新：
        $('#valid_img').click(function () {
        
            $(this)[0].src += '?'
        });
    
    4.认证组件
        valid_str = request.session.get('valid_str')
        if valid_str.upper() == valid_code.upper():
            user = auth.authenticate(username = user, password = pwd)
            if user:
                auth.login(request, user)

### 2.5 网站首页 ###

1.bootstrap搭建页面
    
    2.导航条
        登录：   username / 注销
        未登录： 登录 / 注册
    
    3.for循环
         {
        % for article in article_list %}
         {
        % endfor %}

### 2.6 个人站点 ###

1.文章列表，分类列表，标签列表，日期归档列表
        文章列表：     /blog/egon/
        分类列表：     /blog/egon/cate/python
        标签列表：     /blog/egon/tag/生活
        日期归档列表： /blog/egon/archive/2018-06
    
    2.模板继承
        {
        % extends 'base.html' %}
    
        {
        % block content %}
        {
        % endblock content%}}
    
    3.自定义标签
        /blog/templatetags/my_tag.py
    
        @register.inclusion_tag('menu.html')
        def get_menu(username):
            ...
            return {
        } # 去渲染 menu.html
    
    4.分组查询 .annotate() / extra()应用
        多表分组
            tag_list = Tag.objects.filter(blog=blog).annotate(
                count = Count('article')).values_list('title', 'count')
    
        单表分组 / DATE_FORMAT() /  extra()
            date_list = Article.objects.filter(user=user).extra(
                select={
        "create_ym": "DATE_FORMAT(create_time,'%%Y-%%m')"}).values('create_ym').annotate(
                c = Count('nid')).values_list('create_ym', 'c')
    
    5. 时间、区域配置
         TIME_ZONE = 'Asia/Shanghai'
         USE_TZ = False

### 2.7 文章详情 ###

1.模板继承
        article = Article.objects.filter(pk=article_id).first()
        {
        % extends 'base.html' %}
        {
        % block content %}
             ...
            {
        {
         article.articledetail.content|safe }}
        {
        % endblock content %}

### 2.8 后台管理 ###

1.支持文章编辑
    2.支持富文本编辑器（支持渲染已有文章）
    3.支持删除文章
    4.防止Xss攻击（基于BS4）
     # 防止xss攻击,过滤script标签
            soup = BeautifulSoup(content, "html.parser")
            for tag in soup.find_all():
    
                if tag.name == "script":
                    tag.decompose()

### 2.9 批量建立测试数据 ###

*  1.定制建立测试数据
 *  2.初始化得到100条用户信息，以及为100个客户分别添加文章、博客的详细信息

**核心代码**

def supreme(request):
        """
        这是数据初始化视图，将会生成99条测试数据，用户名为管理员输入的字符后，加1_99.
        密码为管理员填入的密码
