Why do we add our Django app to installed apps?

Question

Can someone explain to me why we add our Django app in the settings.py file under installed apps . Or and please explain better than - "So that Django knows we have created a new app"

Answer 1

In urls.py while defining name of view function that will handle the requested url we can use 'app_name.function_name' directly to refer to the specific function without importing views.py in your urls.py.

It actually mainly helps in url management.
