Setting Up an Environment Within a virtualenv

Here I use nftwall as the project name and directory name.

mkdir nftwall
cd nftwall
virtualenv -p python .
source bin/activate
pip install django
mkdir src
cd src
django-admin startproject nftwall .

You can now start the project for testing:

python manage.py runserver

In nftwall/settings.py, enter the DNS name through which you access the service in the browser:

ALLOWED_HOSTS = ['host1.mydomain.de']

Sync the settings with the project.

python manage.py migrate

Change the listening IP and the hostname through which the service may be accessed.

python manage.py runserver [::]:8000

Create a new superuser

python manage.py createsuperuser

Creating Your First App

In the project root

python manage.py startapp products

Edit the models.py file in the products subdirectory

class Product(models.Model):
title = models.TextField()
description = models.TextField()
price = models.TextField()
summary = models.TextField()

Fill the admin.py file in the same directory (relative import)

from .models import Product
admin.site.register(Product)

Add the app in settings.py

INSTALLED_APPS = [
[...]
'products',a
[...]
]

After every change to models.py you need to run makemigrations and migrate.

python manage.py makemigrations
python manage.py migrate

You can also create records by using the Django command line.

python3 manage.py shell
from products.models import Product
Product.objects.create(title="test2", description="whatever", price="1234", summary="sweet")

Now let's make some modifications and first delete some files:

• Files in the migrations directory
• Delete pycache directory
• Delete sqlite db

Now back to models.py
