Database structure

Launching project

General

1. Create database shop_db with Postgres 16 and new server in PGAdmin:

• Host name/address: localhost
• Port: 5433
• Maintenance database: postgres
• Username: postgres

2. Add .env.prod (with Docker Compose) or .env.local (without Docker Compose), and .env.stripe to the project's root.

Generate new Django secret key:

from django.core.management.utils import get_random_secret_key

print(get_random_secret_key())

With Docker Compose

1. Create network: docker network create shop-net

2. Build Docker containers: docker compose up -d --build

3. To authenticate with Stripe, go to: https://dashboard.stripe.com/stripecli/confirm_auth?t=... (see Docker Desktop logs for full URL)

Remove Docker containers: docker compose down

Without Docker Compose

Collect static files

cd backend
python manage.py collectstatic --noinput --settings=backend.settings.local

Launch project

cd backend
python -m uvicorn backend.asgi:application --reload

Apply migrations

cd backend
# Make new migrations
python manage.py makemigrations --settings=backend.settings.local
# Apply migrations
python manage.py migrate --settings=backend.settings.local

Lanch RabbitMQ

1. Start Docker Desktop.

2. Run commands in terminal:

docker pull rabbitmq
docker run -it --rm --name rabbitmq -p 5672:5672 -p 15672:15672 rabbitmq:management

3. RabbitMQ interface is available at http://127.0.0.1:15672

Run a Celery worker

cd backend
python -m celery -A backend worker --pool=solo -l info

Launch Redis

# Once:
sudo add-apt-repository universe
sudo apt install redis
sudo service redis-service restart

# Always:
sudo service redis-server start
sudo service redis-server status
# Status: "Ready to accept connections"
redis-cli
