There are different approaches to getting the number of active users on your Django website, depending on how you define "active". Here are some suggestions:

Session-based approach: In Django, a user's session is created when they first visit your website and lasts until they close their browser or log out. You can use Django's built-in session framework to keep track of active users. To count active sessions, you can query the session table in your database and filter out expired sessions. Here's an example:

from django.contrib.sessions.models import Session
from django.utils import timezone

active_sessions = Session.objects.filter(expire_date__gte=timezone.now())
active_users_count = active_sessions.count()

This will give you the number of currently active sessions, which you can assume to be the number of active users.

Middleware-based approach: You can write a custom middleware that intercepts each request and updates a counter for the number of active users. Here's an example:

class ActiveUsersMiddleware:
    def __init__(self, get_response):
        self.get_response = get_response
        self.active_users_count = 0
        
    def __call__(self, request):
        response = self.get_response(request)
        if request.user.is_authenticated:
            self.active_users_count += 1
        return response

This middleware counts the number of authenticated users who make requests to your website. To use it, add it to your MIDDLEWARE setting in settings.py and then access the active_users_count attribute from your views or templates.

MIDDLEWARE = [
    # ...
    'path.to.ActiveUsersMiddleware',
    # ...
]

Real-time analytics tools: You can use third-party tools such as Google Analytics or Mixpanel to track the number of active users in real-time. These tools require you to add some JavaScript code to your templates and set up an account with the provider.

Note that these approaches may not be completely accurate or may have some performance impact on your website, so use them judiciously.
