My personal website and blog. This is a work in progress and will be updated as I have time.

Feel free to fork the project, but the content is mine. Using Calver of YY.MM.DD

Drop all tables for POSTGRES

DO $$ DECLARE
    r RECORD;
BEGIN
    -- if the schema you operate on is not "current", you will want to
    -- replace current_schema() in query with 'schematodeletetablesfrom'
    -- *and* update the generate 'DROP...' accordingly.
    FOR r IN (SELECT tablename FROM pg_tables WHERE schemaname = current_schema()) LOOP
        RAISE NOTICE 'Dropping table: %', r.tablename;
        EXECUTE 'DROP TABLE IF EXISTS ' || quote_ident(r.tablename) || ' CASCADE';
    END LOOP;
END $$;

We use Alembic for database migration management. The project has been initialized with a baseline migration that represents the current database schema state.

make alembic-current

Shows which migration is currently applied to the database.

make alembic-history

Displays all available migrations and their status.

make alembic-rev

After making changes to your SQLAlchemy models in src/db_tables.py, run this command to generate a new migration. You'll be prompted to enter a descriptive name for the migration (e.g., "add_user_bio_field", "create_audit_table").

make alembic-migrate

Applies all pending migrations to upgrade your database to the latest schema version.

make alembic-downgrade

Downgrades your database to a previous migration. You'll be prompted to enter the revision name to downgrade to.

1. Make changes to your models in src/db_tables.py
2. Generate a migration:

   make alembic-rev
   # Enter descriptive name when prompted

3. Review the generated migration in alembic/versions/ before applying
4. Apply the migration:

   make alembic-migrate

• Always review generated migrations before applying them, especially in production
• Test migrations on development databases first
• Backup your database before applying migrations in production
• Commit migration files to version control along with model changes
• The project uses a baseline migration approach for existing databases

• Alembic configuration: alembic.ini
• Environment setup: alembic/env.py (configured for async database operations)
• Database URL is automatically set from environment variables via scripts/env.sh
