  • 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>

    views.py

    1 def muban(request):
