python之django母板頁面的使用

發布時間:2020-10-18 15:25:04 來源:腳本之家 閱讀:131 作者:楓若雪 欄目:開發技術

其實就是利用{% block xxx %}   {% endblock %}的方式定義一個塊,相當于占位。存放在某個html中,比如base.html

然后在需要實現這些塊的文件中,使用繼承{% extends "base.html" %}的方式引入母板文件,然后在{% block xxx %}......{% endblock %}塊定義中實現具體的內容。

base.html示例:注意塊的定義。

<!DOCTYPE html>
<html lang="zh-CN">
<head>
  <meta charset="utf-8">
  <meta http-equiv="X-UA-Compatible" content="IE=edge">
  <meta name="viewport" content="width=device-width, initial-scale=1">

  <meta name="description" content="">
  <meta name="author" content="">
  <link rel="icon"  rel="external nofollow" >
  <link rel="stylesheet" href="https://cdn.bootcss.com/font-awesome/4.7.0/css/font-awesome.css" rel="external nofollow" >
  <title>所有的書都在這里</title>
  {% block page_css %}
  {% endblock %}
  {% block page_js %}
  {% endblock %}

  <!-- Bootstrap core CSS -->
  <link  rel="external nofollow" rel="stylesheet">
