html - 如何访问 django-admin 页面并扩展它？

Question

我会用一种非常简单的方式来表达。 我想访问特定页面的 django-admin HTML。

这是图片:

我想要访问的页面。

路径如下 http://127.0.0.1:8000/admin/listings/listing/12/change/

我只想向其中添加自定义 html 按钮，单击后将引入一个字段。

我如何扩展这个特定页面的 html。

这是您建议的代码

      {% extends "admin/base_site.html" %}
      {% load i18n admin_urls static admin_modify %}

      {% block extrahead %}{{ block.super }}
      <script type="text/javascript" src="{% url 'admin:jsi18n' %}"></script>
      {{ media }}
