Hi Tobiah!

Soon we will release a migration tool which should help with updating the
database schema.

Until this, during the early stage of development you can drop all tables
and re-create them:

    # update_db.py

    from models import db
    from settings import db_params
    from initial_data import populate_database


Best regards,
Alexander Kozlovsky
