Register an app on a Django project and ready the database

Previous: https://medium.com/@merajmasuk/start-a-django-project-from-scratch-d8ea06cabd01

1. Start an app

$ django-admin startapp app1

2. Open project settings settings.py . It should be inside the main project folder (i.e. project1).

$ nano project1/settings.py

and add the line ‘app1’ to the following part as shown

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'app1',
]

3. Django has SQLite as default database solution. To use the database, we must first migrate the project related tables (i.e. admin, auth, contenttypes, sessions etc.) to the database.

$ python manage.py makemigrations

Migrate

$ python manage.py migrate

4. Create admin for the database and give user, email and password

$ python manage.py createsuperuser

5. Now whenever our app is running, we can access the admin panel for the SQLite database using the url http://localhost:8000/admin/

$ python manage.py runserver

Whenever any new changes made to our models in the Django project, we need to migrate.
