个人中心标签页导航

1. 新页面user.html,用<ul ><li role="presentation"> 实现标签页导航。
   <ul class="nav nav-tabs">
     <li role="presentation"><a href="#">Home</a></li>
     <li role="presentation"><a href="#">Profile</a></li>
     <li role="presentation"><a href="#">Messages</a></li>
   </ul>

   <ul class="nav_ul">
       <li role="presentation"><a href="#">全部问答</a> </li>
       <li role="presentation"><a href="#">全部评论</a> </li>
       <li role="presentation"><a href="#">个人信息</a> </li>
   </ul>

    

2. user.html继承base.html。
   重写title,head,main块.
   将上述<ul>放在main块中.
   定义新的块user。
   

   {% extends'base.html' %}
   {% block title %}个人中心 {% endblock %}
   {% block head %}
       <style>
           .nav_ul li{
               float: left;
               list-style: none;
               margin: 10px;
               border-bottom: outset;
           }
       </style>
   {% endblock  %}
   {% block main %}
   <ul class="nav_ul">
       <li role="presentation"><a href="#">全部问答</a> </li>
       <li role="presentation"><a href="#">全部评论</a> </li>
       <li role="presentation"><a href="#">个人信息</a> </li>
   </ul>
       {% block user %}{% endblock %}
   {% endblock %}

    

3. 让上次作业完成的个人中心页面，继承user.html，原个人中心就自动有了标签页导航。

   {% extends'user.html' %}
   
   {% block user %}
       <div class="post">
       <h3 class="title "><span>{{ username }}<br><small>全部问答</small></span></h3>
       <ul class="list">
            {% for foo in questions %}
          <li class="post_item">
              <a href="#" class="light">{{foo.author.username }}</a>
              <img width="48" height="48" class="pf" src="https://ss2.bdstatic.com/70cFvnSh_Q1YnxGkpoWK1HF6hhy/it/u=4066191998,32277144&fm=27&gp=0.jpg" alt="">
              <p class="post_item">{{ foo.detail }}</p>
              <span class="foot">发布于  {{ foo.create_time }}</span>
          </li>
          <hr>
   {% endfor %}
       </ul>
       </div>
   
       <div class="post">
       <h3 class="title "><span></span>{{ user }}<br><small>全部评论  <span></span></small></h3>
       <ul class="list">
            {% for foo in comments %}
          <li class="post_item">
              <a href="#" class="light">{{foo.author.username }}</a>
              <img width="48" height="48" class="pf" src="https://ss2.bdstatic.com/70cFvnSh_Q1YnxGkpoWK1HF6hhy/it/u=4066191998,32277144&fm=27&gp=0.jpg" alt="">
              <p class="post_item">{{ foo.detail }}</p>
              <span class="foot">发布于  {{ foo.create_time }}</span>
          </li>
          <hr>
   {% endfor %}
       </ul>
       </div>
   
       <div class="post">
           <h3 class="title "><span></span>{{ user }}<br><small>个人信息  <span></span></small></h3>
            <ul class="post_item">
                <li class="post_item">用户：{{ username }}</li>
                <li class="post_item">编号：</li>
                <li class="post_item">昵称：</li>
                <li class="post_item">文章数：</li>
       </ul>
       </div>
   
   {% endblock %}

    

4. 制作个人中心的三个子页面，重写user.html中定义的user块。

   {% extends'usercenter.html' %}
   
   {% block user %}
   
       <div class="post">
           <span class="glyphicon glyphicon-info-sign" aria-hidden="true"></span>全部问答
            <ul class="list">
            {% for foo in questions %}
          <li class="post_item">
              <a href="#" class="light">{{foo.author.username }}</a>
              <img width="48" height="48" class="pf" src="https://ss2.bdstatic.com/70cFvnSh_Q1YnxGkpoWK1HF6hhy/it/u=4066191998,32277144&fm=27&gp=0.jpg" alt="">
              <p class="post_item">{{ foo.detail }}</p>
              <span class="foot">发布于  {{ foo.create_time }}</span>
          </li>
          <hr>
   {% endfor %}
       </ul>
       </div>
   
   {% endblock %}

   {% extends'usercenter.html' %}
   
   {% block user %}
   
       <div class="post">
           <span class="glyphicon glyphicon-info-sign" aria-hidden="true"></span>全部评论
            <ul class="list">
            {% for foo in comments %}
          <li class="post_item">
              <a href="#" class="light">{{foo.author.username }}</a>
              <img width="48" height="48" class="pf" src="https://ss2.bdstatic.com/70cFvnSh_Q1YnxGkpoWK1HF6hhy/it/u=4066191998,32277144&fm=27&gp=0.jpg" alt="">
              <p class="post_item">{{ foo.detail }}</p>
              <span class="foot">发布于  {{ foo.create_time }}</span>
          </li>
          <hr>
   {% endfor %}
       </ul>
       </div>
   
   {% endblock %}

   {% extends'usercenter.html' %}
   
   {% block user %}
   
       <div class="post">
           <span class="glyphicon glyphicon-info-sign" aria-hidden="true"></span>个人资料
            <ul class="post_item">
                <li class="post_item">用户：{{ username }}</li>
                <li class="post_item">编号：</li>
                <li class="post_item">昵称：</li>
                <li class="post_item">文章数：</li>
            </ul>
       </div>
   
   {% endblock %}

    

5. 思考 如何实现点标签页导航到达不同的个人中心子页面。
