如何解决从数据库中检索数据并通过Django中的AJAX以HTML形式显示
最近我正在使用django框架开发博客应用程序，现在我不知道如何通过HTML形式的ajax从数据库中检索数据，例如，如果用户要编辑自己的帖子，则该页面将重定向到blog_post页面我想将发布的数据设置为blog_post页面。因此，每当用户去编辑该帖子时，都会提到该发布的帖子，并且用户可以轻松地对其进行编辑。
这是我的代码，
blog_post.html
{% load static %}
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width,initial-scale=1,shrink-to-fit=no">
<meta name="description" content="">
<meta name="author" content="">
