Previous answer seems to be outdated as ModelSchema is now deprecated.

You should instead SQLAlchemyAutoSchema with the proper options.

class NodeSchema(SQLAlchemyAutoSchema):
    class Meta:
        model = Node
        load_instance = True
        sqla_session = db.session

node_schema = NodeSchema()

# then when you need to update a Node orm instance :
node_schema.load(node_data, instance=node, partial=True)
db.session.update()
