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:

  1. 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:
1
2
3
4
5
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.

  1. 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:
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
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.

1
2
3
4
5
MIDDLEWARE = [
    # ...
    'path.to.ActiveUsersMiddleware',
    # ...
]


  1. 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.

Additionally, you can also consider using Django's django.contrib.auth module to track active users. The last_login field of the User model is automatically updated each time a user logs in. You can use this field to determine active users in a specific timeframe.


Here's an example of how you can get the number of active users within the last 15 minutes:

1
2
3
4
from django.contrib.auth.models import User
from django.utils import timezone

active_users_count = User.objects.filter(last_login__gte=timezone.now() - timezone.timedelta(minutes=15)).count()


You can adjust the timeframe as per your requirements. This approach considers active users based on their login activity rather than relying on sessions or requests.


Remember to import the necessary modules (User and timezone) before using the code.


Lastly, make sure to consider the trade-off between accuracy and performance when counting active users. Depending on your website's traffic and the frequency of updates, the implementation choice will vary.
