Django模板之模板继承(extends/block)

Django模版引擎中最强大也是最复杂的部分就是模版继承了。模版继承可以让您创建一个基本的骨架模版,它包含您站点中的全部元素,并且可以定义能够被子模版覆盖的 block 

模板继承:

1.    新建muban.html模板文件,在形影需要替换的不同位置加上不同名称的block标签

{% block content %}

模板内容

{% endblock %}或者{% endblock content %}

 

2.    在新的html文件开头写:

{% extends "muban.html" %}

 

3.    接下来重写模板中的block标签内容:

注意:每个block标签不能同名,可以有多个(一般css/js/内容都可以有)

{% block content %}

……

{% endblock %}或者{% endblock content %}

 

4.    要想继承保留模板block中的内容,在重写时加上

{{ block.super }}

 

模板继承演示:

  muban.html  

 1 <!DOCTYPE html>
 2 <html lang="en">
 3 <head>
 4     <meta charset="UTF-8">
 5     <style>
 6         * {margin: 0; padding: 0; }
 7         .c1, .nav {margin: 0 auto; width: 1200px; background-color: #d6d6d6; color: white; }
 8         .fixed:after {content: "";display: block; clear: both; }
 9         .navleft {float: left; }
10 .navright {float: right; }
11         ul, li {list-style: none; display: inline; }
12         .contentleft {float: left; width: 300px; background-color: red; height: 100px; }
13         .contentright {float: left; width: 900px; height: 100px;            background-color: green; }
14         .c2 {margin: auto auto; text-align: center;vertical-align: middle; }
15     </style>
16     <title>模板继承测试</title>
17 </head>
18 <body>
19 <div class="c1">
20     <div class="nav fixed">
21         <div class="navleft ">

28         <div class="navright">

42         </div>
43         <div class="contentright">
44             <div class="c2">
45                 {% block content %}
46                     模板内容---简介
47                 {% endblock %}
48             </div>
49         </div>
50     </div>
51  
52 </div>
53 </body>
54 </html>

  muban_1.thml

1 {% extends "muban.html" %}
2 {% block content %}
3     <h2>You never fail just when you give up!</h2>
4 {% endblock %}

  muban_2.thml

1 {% extends "muban.html" %}
2 {% block content %}
3     {{ block.super }}<!--继承保留模板对应标签的内容-->
4     <h2>Do whatever you want and smile veryday!</h2>
5 {% endblock %}

views.py

1 def muban(request):
2     return render(request,"muban.html")
3 def muban_1(request):
4     return render(request,"muban_1.html")
5 def muban_2(request):
6     return render(request,"muban_2.html")
