you need to wrap your <button>with <form>tag, as following snippet:
你需要<button>用<form>标签包裹你的标签，如下片段：
<form action='actionUrl' method='GET'>
<button type='submit'> sort me</button>
</form>
and in your urls.pymodule you should point the actionUrl with specific view from the views.pymodule as follow:
在您的urls.py模块中，您应该使用views.py模块中的特定视图指向 actionUrl，如下所示：
from django.urls import path
from . import views
urlpatterns = [
path(actionUrl, views.yourSort),
]
you should more read about request lifecycle on Django:
您应该更多地了解 Django 上的请求生命周期：
- user submit request
- Django tries to get the first match between request's URL and routes defined in
urls.py - the request is passed to the matched view
- the view get executed, usually this some model processing
- a response (template) is returned by the view as
HttpResponse
- 用户提交请求
- Django 尝试获取请求的 URL 和定义的路由之间的第一个匹配
urls.py - 请求被传递到匹配的视图
- 视图被执行，通常这是一些模型处理
- 视图返回响应（模板）为
HttpResponse
