To get the count of all logged-in users in Django, you can use the `Session` model to filter sessions that are currently active. Here's a simple way to do it:

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

# Get all active sessions
active_sessions = Session.objects.filter(expire_date__gte=timezone.now())

# Count of logged-in users
logged_in_user_count = active_sessions.count()
```

To get a list of logged-in users, you can extract the user IDs from the sessions:

```python
logged_in_users = [session.get_decoded().get('_auth_user_id') for session in active_sessions]
