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>

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 'jianshu.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 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 title %}个人中心{% endblock %}
{% block user %}
    <br>
    <div class="page-header"><br>
        <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 post %}
                <li class="list-group-item">
                    <span class="glyphicon glyphicon-heart-empty" aria-hidden="true"></span>
                    <a href="#">{{ 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>{{ user }}<br>
            <small>全部评论<span class="badge"></span></small>
        </h3>
        <ul class="list-group" style="">
            {% for foo in comments %}
                <li class="list-group-item">
                    <span class="glyphicon glyphicon-heart-empty" aria-hidden="true"></span>
                    <a href="#">{{ 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>{{ user }}<br>
            <small>个人信息<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：{{ id }}</li>
            <li class="list-group-item">昵称：{{ username }}</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 'user.html' %}
{% block user %}
    <div>全部问答</div>
{% endblock %}

{% extends 'user.html' %}
{% block user %}
    <div>全部评论</div>
{% endblock %}

{% extends 'user.html' %}
{% block user %}
    <div>个人信息</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。
