模板标签及模板的继承与引用

1.常用的模板标签
- 作用是什么:提供各种逻辑
view.py:
def index(request):
#模板标签
--常用标签
总结：语法
{% tag %} {% endtag %}
{% tag 参数参数 %}

示例

展示页index.html，包含for标签，if标签，url标签

{% extends 'teacher/base.html' %}
{% load static %}
{% load customer_filter %}
{% load customer_tags %}
{% block title %}首页{% endblock %}
{% block link %}
    <link href="{% static 'teacher/css/starter-template.css' %}" rel="stylesheet">
{% endblock %}
{% block content %}
     <body>
.....
        <table class="table">
            <tr>
                <th>序号</th>
                <th>姓名</th>
                <th>年龄</th>
                <th>性别</th>
            </tr>
            <tr>
                {% for stu in student %}
                    <tr {% if stu.sex == 0 %}style="color: red" {% endif %}>  #女性显示为红色
                        <td><a href="{% url 'teacher:detail' stu.id %}">{{ forloop.counter }}</a></td><td>{{ stu.name }}</td>
                        <td>{{ stu.age }}</td>
                        <td>{{ stu.sex|male:'en' }}</td></tr>
                {% endfor %}
            </tr>

        </table>
      </div>

    </div><!-- /.container -->
    <div style='position: fixed;bottom: 0px;'>
        {% include 'teacher/ad.html' %}
    </div>
    ....
  </body>
{% endblock %}

views.py代码如下：

def index(request):

    students = [
        {'id':10,'name':'tuple','age':18,'sex':1},
        {'id':20,'name':'xinlan','age':15,'sex':0},
        {'id':30,'name':'xiaopo','age':21,'sex':0},
        {'id':40,'name':'gulu','age':19,'sex':1},
        {'id':50,'name':'shiwei','age':20,'sex':0},
    ]
    format_str = '%Y-%m-%d %H:%M:%S'
    return  render(request,'teacher/index.html',context={
        'student':students,
        'format_str':format_str
    })

页面效果如下：

2.模板的继承与引用
-引用 include 标签广告插入，在index.html中使用include标签引用广告页。

    <div style='position: fixed;bottom: 0px;'>
        {% include 'teacher/ad.html' %}
    </div>

继承 extends 标签
block
