⚙️ Prerequisites

• Python 3.12+
• Docker & Docker Compose
• (Optional) Virtualenv for local development

---

📦 Setup Instructions

🔧 1. Create Virtual Environment (Optional)

python3 -m venv env
source env/bin/activate
pip install -r requirements.txt

🔧 2. Configure Environment

Edit the .env file:

DEBUG=True
SECRET_KEY=your-secret-key
DJANGO_ALLOWED_HOSTS=localhost,127.0.0.1,[::1]

POSTGRES_DB=taskflow
POSTGRES_USER=postgres
POSTGRES_PASSWORD=postgres
POSTGRES_HOST=localhost
POSTGRES_PORT=5432

CELERY_BROKER_URL=amqp://guest:guest@localhost:5672//

---

🧪 Development Mode (Local Python)

Run Django and Celery locally. Use Docker for DB & RabbitMQ only.

./start-dev-services.sh      # Start db + rabbitmq only
python manage.py runserver   # Run Django locally
celery -A taskflow_api worker --loglevel=info  # Start Celery

Local URLs:

• API: http://localhost:8000/api/tasks/
• Docs: http://localhost:8000/docs/

---

🧪 Run Tests

▶️ Run all tests

pytest

▶️ With coverage

pytest --cov=. --cov-report=term-missing

▶️ (Optional) HTML Coverage Report

pytest --cov=. --cov-report=html
# Open htmlcov/index.html in your browser

---

🧩 Celery Background Logging

When a task is created via API, a background task (log_task_action) is triggered:

• Logs to logs/task_activity.log
• Format:

[2025-09-14 19:45:00] Task #12 ('Example Task') was created via Celery background task.

---

🏭 Production Mode (Dockerized Full Stack)

▶️ Start All Services

./run_server.sh

This command will:

• Build the Docker image
• Run Django with Gunicorn
• Serve via Nginx on port 80
• Collect static files into a volume
• Expose the full app on http://localhost/

Alternatively:

docker compose up --build

---

🌐 Accessing App

• Web App: http://localhost/
• API: http://localhost/api/tasks/
• Swagger Docs: http://localhost/docs/
• RabbitMQ UI: http://localhost:15672 (user/pass: guest/guest)
