Creating and linking an app

Creating an App

First, we need to create an app. In this case, we want to create an app that's going to hold the code for our database.

We create an app by running the following command:

python manage.py startapp <APP_NAME>

We're going to call our app database, so we'll run the following command in out terminal:

python manage.py startapp database

You'll now see that there's a new directory (folder) called database.

Linking an App

Next, we want to tell Django that we've added a new app. Just like before, we go into settings.py and changed the INSTALLED_APPS variable. We want to all 'database' to the list, as shown below:

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'database'
]
