link looks something like this: This is how the filter works on 1C Bitrix

Answer 1

1. learn how to route https://docs.djangoproject.com/en/3.1/topics/http/urls/ so that your "product filter" immediately generates the desired url
2. do it at the web server level, for example, rewrite in nginx , a quick crutch, but then why do you need django here, write in php.
3. switch to 1C Bitrix
