Tracks the time of each user's last action
Using middleware, django-online-users will keep track of each user and the timestamp of their last action in the database.
Admins can see this data in the admin portal, and the database can be queried using timedeltas.
This is meant for smaller applications as each HTTP request will result in a database entry update.
- Python: 2.7, 3.3, 3.4, 3.5, 3.6
- Django: 1.11+
- Add "online_users" to your
INSTALLED_APPS
INSTALLED_APPS = [
...
'online_users',
]
- Add the
OnlineNowMiddleware
to yourMIDDLEWARE_CLASSES
after theSessionMiddleware
MIDDLEWARE_CLASSES = (
...
'online_users.middleware.OnlineNowMiddleware',
)
- Run
python manage.py makemigrations
andpython manage.py migrate
to create the tables in the database.
If this application is intended to be used in an application already in production, it's recommended that the middleware be added to the settings file after the application has been installed and the database has been migrated. Otherwise, HTTP requests may result in a 500 error.
- The time of the last action for each user can be seen in the admin portal at http://127.0.0.1:8000/admin/online_users/onlineuser/
- To retrieve the current number of users online in the last 15 minutes
from datetime import timedelta
...
user_activity_objects = OnlineUserActivity.get_user_activities()
number_of_active_users = user_activity_objects.count()
- A timedelta can also be specified to the
get_user_activities()
with to find activity
from datetime import timedelta
...
user_activity_objects = OnlineUserActivity.get_user_activities(timedelta(minutes=60)
users = (user for user in user_activity_objects)
OnlineUserActivity holds two values: user, the user in question, and last_activity, a timestamp stored as a DateTimeField.
OnlineUserActivity.get_user_activities()
will return OnlineUserActivity objects for the last 15 minutes by default.
Developers can also pass in a time delta of a different length of time for the query. The response is a QuerySet containing
the active users during that time period, and the items are sorted in descending chronological order.
