Example Code

# example potential pseudo-code of desired functionality

# import existing SQLAlchemy ORM Table
from project.sqlalchemy.models import Table

# convert SQLA Table ORM to SQLModel Table
SQLM_Table = SQLModel.convert(Table)

# or batch convert a set of SQLAlchemy ORMs
from project.sqlalchemy import models
SQLM_models = sqlmodel_batch_convert(models)

Description

In your docs, you only describe creating a db, tables and SQLModel ORM from scratch. If you already have a set of defined SQLAlchemy ORMs for an existing db, is there a mechanism for converting existing SQLAlchemy ORMs into SQLModel ORMs? I looked through the docs but couldn't find anything related to that. I provide some desired functionality as pseudocode, but maybe this functionality already exists?

I am currently trying to implement SQLModel.convert ... if I end up developing something useful I will share here.

Also curious to hear if in 2025 there's perhaps a better approach for integrating existing sqlalchemy models with sqlmodel
