it's possible to connect a signal of "django.db.models.signals" with a function of "UnicornView" ?

Hello, I would like to know how I can execute a function of "UnicornView" from one of the signals of "django.db.models.signals". As far as I know, they are only usually called functions and not classes.
Thank you very much

Signals will fire outside of the request/response lifecycle, so if your idea is that a signal will update a page, then that's not really possible with Unicorn. If you want a change reflected on the page without triggering a request, then the closest you can get to that is a poll. Otherwise, you will have to look into websockets (Django Channels) which might be able to provide that functionality (that's out of scope for Unicorn, though).

However, If you just want a signal to call the same code that you already have in a UnicornView function, personally, I would move that another module/function that gets imported and run from the signal and from a UnicornView function.

Hope that helps!
