SQLAlchemy integration with the marshmallow (de)serialization library.
Declare your models

from sqlalchemy.orm import scoped_session, sessionmaker, relationship, backref
engine = sa.create_engine("sqlite:///:memory:")

class Author(Base):
__tablename__ = "authors"
id = sa.Column(sa.Integer, primary_key=True)
name = sa.Column(sa.String)
def __repr__(self):
return "<Author(name={self.name!r})>".format(self=self)
class Book(Base):

title = sa.Column(sa.String)

Base.metadata.create_all(engine)Generate marshmallow schemas
