The models/__init__.py imports all ORM model classes (Store, Product, Coupon, etc.) which registers their table definitions with Base.metadata. Importing Base directly from models.base skips this registration, so alembic's create_all() on fresh databases fails to create app tables. Co-Authored-By: Paperclip <noreply@paperclip.ing>
