【中文标题】如何更改扩展基本模板的 Django HTML 视图文件？【英文标题】：How do I make changes to my Django HTML view file that extends a base template? 【发布时间】：2022-01-09 13:35:57 【问题描述】：我有一个正在处理的 Django 测试项目，并且已经工作了几个小时，但我被困住了。我无法将其他 html 语法添加到我的 html 文件中，以将基本模板扩展到其中。
我有一个在我的 html 视图上工作的基本模板，但是，当我在 html 视图中进行更改时，它不会反映。看起来我在 HTML 视图和基本模板之间缺少了一些东西。
下面是 HTML 视图
<!DOCTYPE html>
% extends "base.html" %
<!--https://www.anwita-arun.in/ -->
% block head %
<html lang="en">
<head>
<title>Test Project</title>
</head>
% endblock %
% block body %
<body>
<h1 style="font-size: 250px"> Testing </h1>
<p> aloha </p>
<form method="POST">
<!-- Form creation with post. No method "post" needed -->
% csrf_token %
<!-- Insert token -->
form.as_p
<!-- form variable -->
<input type="submit">
<!-- Form input submission -->
</form>
</body>
% endblock %
下面是基本模板
<!DOCTYPE html>

【问题讨论】：
控制台有错误吗？ 没有。它运行良好，没有错误 【参考方案1】：不是这样的，当你从 base.html 扩展时，你只需要覆盖块，它应该是这样的：
base.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<link rel="stylesheet" type="text/css" href="css/main.css" media="screen" />
% block head %
% endblock %
</head>
<body>
<p>This p tag will always be shown</p>
% block content %
<p>This content is a placeholder, will be overridden.</p>
% endblock %
</body>
</html>
在您继承的模板中
% extend 'base.html' %
% block head %
<link rel="stylesheet" type="text/css" href="css/my_extra_custom_css.css" media="screen" />
% endblock %
% block content %
<h1>Content from my app, overriding the placeholder.</h1>
% endblock %
