Docker Development Environment

For a complete containerized development environment:

1. Docker Compose Setup

# Start all services using Docker Compose
docker-compose -f docker-compose.local.yml up -d

# Services started:

# - redis (Redis cache and task queue)
# - mailpit (Email testing server)
# - django (Django web application)
# - celery-worker (Background task processor)
# - celery-beat (Scheduled task scheduler)
# - celery-flower (Task monitoring)

2. Verify Services

# Check all services are running
docker-compose -f docker-compose.local.yml ps

# Check service logs
docker-compose -f docker-compose.local.yml logs django
docker-compose -f docker-compose.local.yml logs celery-worker

# Access services:
# Django: http://localhost:8000/
# Flower: http://localhost:5555/
# Mailpit: http://localhost:8025/

3. Django Commands in Docker

# Execute Django commands in the container

docker-compose -f docker-compose.local.yml exec django python manage.py createsuperuser
docker-compose -f docker-compose.local.yml exec django python manage.py collectstatic --noinput

# Access Django shell
docker-compose -f docker-compose.local.yml exec django python manage.py shell

Database Management

Development Database Commands

# Reset database (WARNING: Destroys all data)
python manage.py flush --noinput

# Create fresh migrations
python manage.py makemigrations

# Apply migrations
python manage.py migrate

# Show migration status
python manage.py showmigrations

# Create database backup
pg_dump -h localhost -U jobhive_user jobhive_dev > backup.sql

# Restore database backup
psql -h localhost -U jobhive_user jobhive_dev < backup.sql

Useful Database Queries

-- Check recent interview sessions
SELECT id, user_id, status, start_time, completion_percentage 
FROM interview_interviewsession 
ORDER BY start_time DESC LIMIT 10;

-- Check user subscriptions
SELECT u.email, s.name as plan_name, cs.status, cs.start_date
FROM users_user u
JOIN billing_customersubscription cs ON u.id = cs.user_id
JOIN billing_subscriptionplan s ON cs.plan_id = s.id;

-- Check sentiment analysis results
SELECT session_id, overall_sentiment, positive_score, negative_score, created_at
FROM interview_sentimentsession
ORDER BY created_at DESC LIMIT 20;

Testing Setup

1. Running Tests

# Run all tests
python manage.py test

# Run specific app tests
python manage.py test jobhive.interview

# Run with coverage
coverage run --source='.' manage.py test
coverage report

# Run pytest (if preferred)
pytest

# Run with verbose output
pytest -v

# Run specific test file
pytest jobhive/interview/tests/test_models.py

2. Test Database

# Create test-specific settings
export DJANGO_SETTINGS_MODULE=config.settings.test

# Tests will automatically use test database
# Test database is created and destroyed for each test run

3. API Testing

# Test API endpoints
http GET localhost:8000/api/v1/users/me/ Authorization:"Bearer your-jwt-token"

# Create interview session
http POST localhost:8000/api/v1/interview/interviews/ \
  Authorization:"Bearer your-jwt-token" \
  job_id:=123 \
  scheduled_time="2024-02-15T14:00:00Z"

Troubleshooting Common Issues

Database Connection Issues

# Check if PostgreSQL is running
docker-compose -f docker-compose.local.yml ps postgres

# Check PostgreSQL logs
docker-compose -f docker-compose.local.yml logs postgres

# Reset PostgreSQL container
docker-compose -f docker-compose.local.yml down postgres
docker-compose -f docker-compose.local.yml up -d postgres

# Test database connection
python manage.py dbshell

Redis Connection Issues

# Check if Redis is running
docker-compose -f docker-compose.local.yml ps redis

# Test Redis connection
redis-cli ping

# Reset Redis container
docker-compose -f docker-compose.local.yml restart redis

Migration Issues

# Check migration status
python manage.py showmigrations

# Create migrations for changes
python manage.py makemigrations

# Apply specific migration
python manage.py migrate app_name migration_name

# Fake apply migration (if needed)
python manage.py migrate app_name migration_name --fake

# Reset migrations (nuclear option)
find . -path "*/migrations/*.py" -not -name "__init__.py" -delete
find . -path "*/migrations/*.pyc" -delete
python manage.py makemigrations
python manage.py migrate

Celery Issues

# Check Celery worker status
celery -A config.celery_app inspect active

# Check Celery queue status
celery -A config.celery_app inspect reserved

# Purge all tasks from queue
celery -A config.celery_app purge

# Restart Celery worker
# Stop with Ctrl+C and restart
celery -A config.celery_app worker -l info

Permission Issues

# Fix file permissions (Unix/Linux)
chmod +x manage.py
chmod -R 755 staticfiles/
chmod -R 755 media/

# Fix Docker permission issues
sudo chown -R $USER:$USER .

Port Conflicts

# Check what's using port 8000
lsof -i :8000
netstat -tulpn | grep :8000

# Kill process using port
sudo kill -9 $(lsof -t -i:8000)

# Use different port
python manage.py runserver 0.0.0.0:8001

# Test changes
python manage.py test

# Run code quality checks
pre-commit run --all-files

# Commit changes
git add .
git commit -m "Add new interview analysis feature"

# Push changes
git push origin feature/new-interview-analysis

3. Integration Testing

# Run full test suite

# Run specific test categories
python manage.py test jobhive.interview.tests.test_ai_analysis
python manage.py test jobhive.billing.tests

# Test API endpoints
python manage.py test jobhive.interview.api.tests

# Performance testing (if implemented)
python manage.py test --tag=performance
