views.py里面，我们新建Delete类，继承DeleteView

class Delete(DeleteView):# 设置模版文件template_name = 'student/delete.html'# 设置模型外的数据extra_context = {'title': '学生信息删除'}# 设置上下文对象名称context_object_name = 'student'# 设置查询模型model = StudentInfo# 执行成功后跳转地址success_url = '/student/list'

urls.py里加下映射：

path('student/delete/<int:pk>', helloWorld.views.Delete.as_view()),

student下新建delete.html

<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><title>{{ title }}</title>
</head>
<body>
<h3>{{ title }}</h3>
<form method="post">{% csrf_token %}您确定更要删除 id:{{ student.id }} name:{{ student.name }} age:{{ student.age }} 的记录吗 ？<input type="submit" value="确定">
</form>
</body>
</html>

list.hml加下 <a href="/student/delete/{{ student.id }}">删除</a>

<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><title>{{ title }}</title>
</head>
<body>
<h3>{{ title }}</h3>
<a href="/student/create">新增学生</a>
<table border="1"><tr><th>编号</th><th>姓名</th><th>年龄</th><th>操作</th></tr>{% for student in student_list %}<tr><td>{{ student.id }}</td><td>{{ student.name }}</td><td>{{ student.age }}</td><td><a href="/student/{{ student.id }}">查看详情</a><a href="/student/update/{{ student.id }}">修改</a><a href="/student/delete/{{ student.id }}">删除</a></td></tr>{% endfor %}
</table>
<br>
{% if is_paginated %}{% if page_obj.has_previous %}<a href="/student/list?page={{ page_obj.previous_page_number }}">上一页</a>{% endif %}{% for current in paginator.page_range %}{% if current == page_obj.number %}<a href="/student/list?page={{ current }}"><b><font color="blue">{{ current }}</font></b></a>{% else %}<a href="/student/list?page={{ current }}">{{ current }}</a>{% endif %}{% endfor %}{% if page_obj.has_next %}<a href="/student/list?page={{ page_obj.next_page_number }}">下一页</a>{% endif %}
{% endif %}
</body>
</html>

运行测试：浏览器输入：http://127.0.0.1:8000/student/list
