24.Templates的模板继承

许多网页的header和booter都相同，因此可以单独写一个包含着两部分内容的html文件，在其他模板中引用。但是header里包含着用户登录信息经常会改变，如果都写成一样的是不是不会改变了呢。django的模板语言可以解决,类似于子类在继承父类时可以覆盖掉重复功能。用{% block XXX %}{% endblock %}。XXX指的是为了引用时覆盖方便做的标记。{% block title %}课程机构列表 - 慕学在线网{% endblock %}这里让不同网页可以改title，{% block custom_css %}这里让不同网页可以应用不同css，{% block custom_js %}这里让不同网页可以应用不同js，{% block custom_bread %}这里让不同网页显示不同的路径（面包屑），{% block content %}让页面内容可以改,覆盖时顺序无所谓。但在子模板里需要{% load staticfiles %}。base.py
