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 nav-tabs">
        <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>

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: antiquewhite;
        }
    </style>
{% endblock %}

{% block main %}
    <ul class="nav nav-tabs">
        <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="page-header">
        <h3><span class="glyphicon glyphicon-heart-empty" aria-hidden="true"></span>{{ user.username }} <br>
            <small>全部问答<span class="badge"></span></small>
        </h3>
        <ul class="list-group" style="margin: 10px">
            {% for foo in user.question %}
            <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.create_time }}</span>
                <p>{{ foo.detail }}</p>
            </li>
            {% endfor %}
        </ul>
    </div>

    <div class="page-header">
        <h3><span class="glyphicon glyphicon-heart-empty" aria-hidden="true"></span>{{ user.username }} <br>
            <small>全部评论<span class="badge"></span></small>
        </h3>
        <ul class="list-group" style="margin: 10px">
            {% for foo in user.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.create_time }}</span>
                <p>{{ foo.detail }}</p>
            </li>
            {% endfor %}
        </ul>
    </div>

    <div class="page-header">
        <h3><span class="glyphicon glyphicon-heart-empty" aria-hidden="true"></span>{{ user.username }} <br>
            <small>个人信息<span class="badge"></span></small>
        </h3>
        <ul class="list-group" style="margin: 10px">
            <li class="list-group-item">用户：{{ user.username }}</li>
            <li class="list-group-item">编号：{{ user.id }}</li>
            <li class="list-group-item">昵称：</li>
            <li class="list-group-item">文章：</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="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 %}
