Auto generate migrations alembic + SQLAlchemy imperative declaration

Question

I'm exploring a new DDD project using SQLAlchemy and Alembic for the first time. I'd like to use imperative mapping to isolate my domain objects. All the doc I can find about auto generating migrations with Alembic is using declarative mapping. Is it because I have to manually write all migrations if I want to use imperative mapping ?

Answer 1
