Django Verification Loop

# Verify Python version
python --version  # Should match project requirements

# Check virtual environment
which python
pip list --outdated

# Verify environment variables
python -c "import os; import environ; print('DJANGO_SECRET_KEY set' if os.environ.get('DJANGO_SECRET_KEY') else 'MISSING: DJANGO_SECRET_KEY')"

# Type checking
mypy . --config-file pyproject.toml

# Linting with ruff
ruff check . --fix

# Formatting with black
black . --check
black .  # Auto-fix

# Import sorting
isort . --check-only
isort .  # Auto-fix

# Django-specific checks
python manage.py check --deploy

# Check for unapplied migrations
python manage.py showmigrations

# Create missing migrations
python manage.py makemigrations --check

# Dry-run migration application
python manage.py migrate --plan

# Apply migrations (test environment)
python manage.py migrate

# Check for migration conflicts
python manage.py makemigrations --merge  # Only if conflicts exist

# Run all tests with pytest
pytest --cov=apps --cov-report=html --cov-report=term-missing --reuse-db

# Run specific app tests
pytest apps/users/tests/

# Run with markers
pytest -m "not slow"  # Skip slow tests
pytest -m integration  # Only integration tests

# Coverage report
