Description

Hello,

I am building my first api, from a quite complex model (45+ domain objects) - and I would to know if marshmallow could fit my need as I have not found the answer elsewhere.

I use SQL Alchemy with an imperative mapping style: domain objects are defined in domain/model.py while tables are defined in adapters/orm.py.

Each domain object class is then explicitly mapped to its corresponding table.

All the examples I have seen use SQLAlchemy declarative mapping.

Is it possible to use marshmallow, especially the SQLAlchemyAutoSchema, with SQLAlchemy imperative mapping ?

thanks a lot for your help.

Research direction

Start by reviewing the imperative mapping described in domain/model.py and adapters/orm.py, then inspect how SQLAlchemyAutoSchema discovers mapped models. Determine whether this mapping style is supported and document the result, including any relevant limitations or usage guidance.
