Building a generic activity stream application

Many social websites display an activity stream to their users so that they can track what other users do on the platform. An activity stream is a list of recent activities performed by a user or a group of users. For example, Facebook's News Feed is an activity stream. Sample actions can be user X bookmarked image Y or user X is now following user Y.

Create a new application named actions inside your project with the following command:

python manage.py startapp actions

Add the new application to INSTALLED_APPS in the settings.py file of your project to activate the application in your project. The new line is highlighted in bold:

INSTALLED_APPS = [
    # ...
    'actions...
