django-online-users 0.1

Tracks the time of users' last actions.

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.

Requirements

• Python: 2.7, 3.3, 3.4, 3.5, 3.6

• Django: 1.10+

Setup

1. Add “online_users” to your INSTALLED_APPS

INSTALLED_APPS = [
    ...
    'online_users',
]

2. Add the OnlineNowMiddleware to your MIDDLEWARE_CLASSES after the SessionMiddleware

MIDDLEWARE_CLASSES = (
    ...
    'online_users.middleware.OnlineNowMiddleware',
)

3. Run python manage.py migrate to create the tables in the database.

Use

• 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)

API

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.
