How to implement file download in Django?

Question

Django

Hello!
There was such question: how to force to give the file with the data from page at button click? I have implemented file generation. On the site page, the data, respectively, and the variables passed to the template engine change with each page refresh. And I need to download the generated file with the current values ​​of the variables displayed on the page when the button is clicked .
Example:
When the page is updated, a new password is generated each time in views.py, so I need to download a file with this password, and not a regenerated one, when clicking on a button on this page.
Thanks in advance!
