python之django母板頁(yè)面的使用

更新時(shí)間：2018年07月03日 08:16:32 作者：楓若雪

這篇文章主要介紹了python之django母板頁(yè)面的使用,母版頁(yè)用于處理html頁(yè)面相同部分內(nèi)容，小編覺(jué)得挺不錯(cuò)的，現(xiàn)在分享給大家，也給大家做個(gè)參考。一起跟隨小編過(guò)來(lái)看看吧

其實(shí)就是利用{% block xxx %} {% endblock %}的方式定義一個(gè)塊，相當(dāng)于占位。存放在某個(gè)html中，比如base.html

然后在需要實(shí)現(xiàn)這些塊的文件中，使用繼承{% extends "base.html" %}的方式引入母板文件，然后在{% block xxx %}......{% endblock %}塊定義中實(shí)現(xiàn)具體的內(nèi)容。

base.html示例：注意塊的定義。
