Add type hints on django initialization
I have user as foreign key user = models.ForeignKey(settings.AUTH_USER_MODEL, models.CASCADE) But when I access user through related object I can't see auto-completion for user attributes. F.e Unresolved attribute reference 'public_name' for class 'ForeignKey' How can I add type hint that it is actually User model? In django app initialization I am overriding serializers.ModelSerializer with my custom serializer. And overriding is taking place in app/init.py module. Problem is I can't see some attributes that exists in CustomModelSerializer. Pycharm is thinking it is ModelSerializer from drf. Is it possible to hint somewhere that it is CustomModelSerializer. (PS: I know I can import CustomModelSerializer everwhere, but it is a big project and I was looking for solutions with adding type hint or making Pycharm recognize overriding) -

Is there a way to update a webpage after it is loaded in django without doing a periodic check?
I'm trying to do something similar to this question. Basically, I want to have the html page being updated once new information arrives at the server. The information won't come periodically, but rather in bursts. Is there a way for me to trigger the javascript/htmx function via django or is it that I have to do the per-X-seconds check on the browser side? All solutions that I've found are using the periodic check in a script which appears a bit surprising to me. -
