Question

Django

The bottom line is this: there is a django project, one of the applications of which is door control (+ there will be an api for mobile applications) and there is a Raspberry PI that will directly control this door (open / close). How to establish a connection between the server and raspberry? An unauthorized user should not be able to open the door

Answer 1

Well, start the client server on the rapsberry side. It is possible on the same Django, or a more lightweight framework.
When authorized by your server with Django - pull yourself the necessary GPIO pins.
Encrypt connections between your server and client on raspberry via ssl for example.
