Create the new app

Let's start by creating a new app with the django command-line tool:

Create a new empty app with the django command:
```
cd apps
pipenv run django-admin startapp <app_name>
```
For this example, let's assume we created an app called event.

Now open the apps.py file in your <app_name> folder, and add apps. to the name attribue:

backend/apps/event/apps.py
from django.apps import AppConfig

class EventConfig(AppConfig):
    name = 'apps.event'  # add 'apps.' to the name attribute

Then, add your app to the INSTALLED_APPS list in the django settings:

backend/config/settings/base.py
DJANGO_APPS = # ...
THIRD_PARTY_APPS = # ...
COMMON_APPS = [
   # ...
   "apps.event",
]
INSTALLED_APPS = DJANGO_APPS + COMMON_APPS + THIRD_PARTY_APPS

Finally, we need to update your database:
```
pipenv run migrate
```
