    知识点

    各个小模块点击以后有可能会发生跳转到对应的页面,这里主要有3个小模块,标签云、文章归档和文章的详情页面需要添加。主要思路是,点击后发生请求,后端获取到前端的请求再做出响应。

    1 标签云详情页

    前端请求的href【tags.html】

    <li><a href='{% url "biaoqian" %}?tag={{ tag }}'>{{ tag }}</a></li>
    

    请求到了路由【urls.py】

    from django.conf.urls import url
    from blog.views import biaoqian
    
    urlpatterns = [
        url(r'^biaoqian$', biaoqian, name='biaoqian'),
    ]
    

    路由将请求转给视图【views.py】

    def biaoqian(request):
        try:
            # 获取请求的tag参数
            tag_name = request.GET.get('tag', None)
            # 找到tag所对应的Tag对象
            tag_obj = Tag.objects.get(name=tag_name)
            # 使用_set通过一对多关系进行查找
            article_list = tag_obj.article_set.all()
        except Exception as e:
            logging.error(e)
        return render(request, 'biaoqian.html', locals())
    

    视图将数据传递给前段模板渲染【biaoqian.html】

    {% extends 'base.html' %}
    {% load staticfiles %}
    {% block left_content %}
    {% include 'baseblock/ads.html' %}
    <!-- banner代码 结束 -->
    <div class="topnews">
        <h2>{{ request.GET.tag }} 标签云</h2>
        {% for article in article_list%}
        <div class="blogs">
            <ul>
                <h3><a href="/">{{ article.title }}</a></h3>
                <p>{{ article.desc }}</p>
                <p class="autor">
                    <span class="lm f_l">
                        {% for tag in article.tag.all %}
                        <a href="/">{{ tag.name }}</a> 
                        {% endfor %}
                    </span>
                    <span class="dtime f_l">{{ article.date_publish | date:'Y-m-d' }}</span>
                    <span class="viewnum f_r">浏览(<a href="/">{{ article.click_count }}</a>)</span>
                    <span class="pingl f_r">评论(<a href="/">{{ article.comment_set.all.count }}</a>)</span>
                </p>
            </ul>
        </div>
        {% endfor %}
    </div>
    {% endblock %}
    

    2 文章归档详情页(方法与标签云类似)

    前端请求的href【sorts.html】
    silce切片类似于[:4],获取需要的数据

    <li><p><span class="tutime font-size-18"><a href='{% url "archive" %}?year={{ article_date | slice:":4" }}&month={{ article_date | slice:"7:9" }}'>{{ article_date }}</a></span></p></li>
    

    请求转到路由【urls.py】

    from django.conf.urls import url
    from blog.views import archive
    
    urlpatterns = [
        url(r'^archive$', archive, name='archive'),
    ]
    

    路由将请求转给视图【views.py】

    def archive(request):
        try:
            # 先获取用户提交的year和month信息
            year = request.GET.get('year', None)
            month = request.GET.get('month', None)
            # 通过filter过滤出对应年份的数据(icontains是包含)
            article_list = Article.objects.filter(date_publish__icontains=year + '-' + month)
        except Exception as e:
            logging.error(e)
        return render(request, 'archive.html', locals())
    

    视图将数据传递给前段模板渲染【atchive.html】

    {% extends 'base.html' %}
    {% load staticfiles %}
    {% block left_content %}
    {% include 'baseblock/ads.html' %}
    <!-- banner代码 结束 -->
    <div class="topnews">
        <h2>{{ request.GET.year }}年{{ request.GET.month }}月 归档文章</h2>
        {% for article in article_list%}
        <div class="blogs">
            <ul>
                <h3><a href="/">{{ article.title }}</a></h3>
                <p>{{ article.desc }}</p>
                <p class="autor">
                    <span class="lm f_l">
                        {% for tag in article.tag.all %}
                        <a href="/">{{ tag.name }}</a> 
                        {% endfor %}
                    </span>
                    <span class="dtime f_l">{{ article.date_publish | date:'Y-m-d' }}</span>
                    <span class="viewnum f_r">浏览(<a href="/">{{ article.click_count }}</a>)</span>
                    <span class="pingl f_r">评论(<a href="/">{{ article.comment_set.all.count }}</a>)</span>
                </p>
            </ul>
        </div>
        {% endfor %}
    </div>
    {% endblock %}
    

    3 文章详情页面设计

    前端请求的href【sorts.html】
    总共有3个地方:博客首页、文章排行、归档详情页面

    ## index.html【博客首页】
    <h3><a href='{% url "article" %}?id={{ article.id }}'>{{ article.title }}</a></h3>
    
    ## chart.html【文章排行】
    <li><a href='{% url "article" %}?id={{ article_click.id }}' target="_blank">{{ article_click }}</a></li>
    <li><a href='{% url "article" %}?id={{ article_comment.id }}' target="_blank">{{ article_comment }}</a></li>
    <li><a href='{% url "article" %}?id={{ article_recommend.id }}' target="_blank">{{ article_recommend }}</a></li>
    
    ## archive.html【归档详情页面】
    <h3><a href='{% url "article" %}?id={{ article.id }}'>{{ article.title }}</a></h3>
    

    请求转到路由【urls.py】

    from django.conf.urls import url
    from blog.views import article
    
    urlpatterns = [
        url(r'^article/$', article, name='article'),
    ]
    

    路由将请求转给视图【views.py】

    # 文章详情
    def article(request):
        try:
            # 获取文章id
            id = request.GET.get('id', None)
            try:
                # 获取文章信息
                article = Article.objects.get(pk=id)
            except Article.DoesNotExist:
                return render(request, 'failure.html', {'reason': '没有找到对应的文章'})
        except Exception as e:
            print e
            logging.error(e)
        return render(request, 'article.html', locals())
    

    app下面新建一个templatetags目录自定义过滤器【myfilter.py】

    # -*- coding: utf-8 -*-
    from django import template
    register = template.Library()
    
    # 定义一个将日期中的月份转换为大写的过滤器,如8转换为八
    @register.filter
    def month_to_upper(key):
            return ['一', '二', '三', '四', '五', '六', '七', '八', '九', '十', '十一', '十二'][key.month-1]
    

    视图将数据传递给前段模板渲染【article.html】
    这里使用了自定义的过滤器获取对应月份的大写

    {% extends 'base.html' %}
    {% load staticfiles %}
    {% load myfilter %}
    {% block left_content %}
    <div class="postdate">
        <div class="month">{{ article.date_publish | month_to_upper }}</div>
        <div class="date">{{ article.date_publish | date:'d' }}</div>
    </div>
    <div class="title">
        <h2><a href="" rel="bookmark" title="{{ article.title }}">{{ article.title }}</a></h2>
        <div class="postmeta">
            <span class="postmeta_author">{{ article.user.username }}</span>
            <span class="postmeta_category"><a href="" rel="category">{{ article.category.name }}</a></span>
            <span class="postmeta_time">{{ article.date_publish | date:'Y-m-d' }}</span>
        </div>
    </div>
    <div class="entry">
        {{ article.content | safe }}
    </div>
    <span class="tags">
        {% for tag in article.tag.all %}
        <a href="?tag={{ tag.name }}" rel="tag">{{ tag.name }}</a>
        {% endfor %}
    </span>
    {% endblock %}
