个人中心标签页导航

1. 新页面userbase.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 herf="#">Questions</a></li>
           <li role="presentation"><a herf="#">Comments</a></li>
           <li role="presentation"><a herf="#">Information</a></li>
       </ul>

2. 让userbase.html继承base.html。
   重写title,head,main块.
   将上述<ul>的样式放在head块，<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{
               list-style: none;
               float:left;
               margin:10px;
           }
       </style>
   {% endblock %}
   
   {% block main %}
       <ul class="nav_ul">
           <li role="presentation"><a herf="#">Questions</a></li>
           <li role="presentation"><a herf="#">Comments</a></li>
           <li role="presentation"><a herf="#">Information</a></li>
       </ul>
   
       {% block user %}{% endblock %}
   {% endblock %}

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

   {% extends ‘userbase.html‘ %}
   {% block title %}个人中心{% endblock %}
   
   {% block main %}
   
    <div class="page-header">
          <h3><span class="glyphicon glyphicon-user" aria-hidden="true"></span> {{ username }}<br><small>全部问答<span class="badge"></span> </small></h3>
          <ul class="list-group" style="...">
              {% for foo in questions %}
                 <li class="list-group-item">
                     <span class="glyphicon glyphicon-heart-empty" aria-hidden="true"></span>
                     <a herf="#">{{ foo.author.username }}</a>
                     <span class="badge">{{ foo.creat_time }}</span>
   
                     <p style="...">{{ foo.detail }}</p>
                 </li>
              {% endfor %}
          </ul>
   
      </div>
   
      <div class="page-header"...>
          <h3><span class="glyphicon glyphicon-user" aria-hidden="true"></span> {{ username }}<br><small>全部评论<span class="badge"></span> </small></h3>
          <ul class="list-group" style="...">
              {% for foo in questions %}
                 <li class="list-group-item">
                     <span class="glyphicon glyphicon-heart-empty" aria-hidden="true"></span>
                     <a herf="#">{{ foo.author.username }}</a>
                     <span class="badge">{{ foo.creat_time }}</span>
   
                     <p style="...">{{ foo.detail }}</p>
                 </li>
              {% endfor %}
          </ul>
   
      </div>
   
       <div class="page-header"...>
           <h3><span class="glyphicon glyphicon-user" aria-hidden="true"></span> {{ username }}<br><small>全部评论<span class="badge"></span> </small></h3>
           <ul class="list-group" style="...">
   
               <li class="list-group-item">用户：{{ username }}</li>
               <li class="list-group-item">编号：</li>
               <li class="list-group-item">昵称：</li>
               <li class="list-group-item">文章篇数：</li>
   
           </ul>
       </div>
   {% endblock %}

4. 制作个人中心的三个子页面，重写userbase.html中定义的user块，分别用于显示问答、评论、个人信息。
   

   {% extends ‘usercenter.html‘ %}
   
   {% block user %}
   <div class="page-header">
   <span class="glyphicon glyphicon-info-sign" aria-hidden="true">全部问答</span>
   <ul class="list-group"></ul>
   </div>
   
   {% endblock %}

   {% extends ‘usercenter.html‘ %}
   
   {% block user %}
       <div class="page-header">
       <span class="glyphicon glyphicon-info-sign" aria-hidden="true">全部评论</span>
       <ul class="list-group"></ul>
       </div>
   
   {% endblock %}

   {% extends ‘usercenter.html‘ %}
   
   {% block user %}
       <div class="page-header">
       <span class="glyphicon glyphicon-info-sign" aria-hidden="true">个人信息</span>
       <ul class="list-group"></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。

   <li role="presentation"><a href="{{url_for(‘usercenter‘,user_id=user.id,tag=‘1‘)}}">全部问答</a></li>
       <li role="presentation"><a href="{{url_for(‘usercenter‘,user_id=user.id,tag=‘2‘)}}">全部评论</a></li>
       <li role="presentation"><a href="{{url_for(‘usercenter‘,user_id=user.id,tag=‘3‘)}}">个人信息</a></li>

   <a href="{{url_for(‘usercenter‘,user_id=ques.author_id,tag=1)}}">{{foo.author.username}}</a>
