Database Management Skill

This skill details how to manage the application's database, including switching between local and remote environments and handling migrations.

Database Modes

1. Local Development (SQLite)

• Setup: Set USELOCALDB=true in .env.
• File: instance/luxury.db.
• Use Case: Fast iteration, offline development.

2. Remote Production (Azure SQL)

• Setup: Set USELOCALDB=false (or remove from .env).
• Config: Requires DATABASE_URL with valid Azure SQL credentials.
• Use Case: Integration testing, production deployment.

Common Tasks

1. Reset Database

• Action: Delete instance/luxury.db and restart the app.
• Note: app.py automatically calls db.create_all() on startup if tables are missing.
• Warning: This erases all local data (users, products, orders).

2. Schema Changes

• Detect: SQLAlchemy warnings (e.g., overlapping relationships).
• Fix: Update models in app.py.
• Apply: For SQLite, drop/recreate is easiest. For Azure, use migration scripts (not yet automated).

Relevant Files

• app.py (Model definitions: User, Product, Order, OrderItem)
