Project description
Homepage: http://marshmallow-sqlalchemy.rtfd.org/
SQLAlchemy integration with the marshmallow (de)serialization library.
Declare your models
import sqlalchemy as sa
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy.orm import scoped_session, sessionmaker, relationship, backref
engine = sa.create_engine('sqlite:///:memory:')
session = scoped_session(sessionmaker(bind=engine))
Base = declarative_base()
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):
__tablename__ = 'books'
id = sa.Column(sa.Integer, primary_key=True)
title = sa.Column(sa.String)
author_id = sa.Column(sa.Integer, sa.ForeignKey('authors.id'))
author = relationship("Author", backref=backref('books'))
Base.metadata.create_all(engine)
Generate marshmallow schemas
from marshmallow_sqlalchemy import ModelSchema
class AuthorSchema(ModelSchema):
class Meta:
model = Author
class BookSchema(ModelSchema):
class Meta:
model = Book
# optionally attach a Session
# to use for deserialization
sqla_session = session
author_schema = AuthorSchema()
(De)serialize your data
author = Author(name='Chuck Paluhniuk')
book = Book(title='Fight Club', author=author)
session.add(author)
session.add(book)
session.commit()
author_schema.dump(author).data
# {'books': [123], 'id': 321, 'name': 'Chuck Paluhniuk'}
author_schema.load(dump_data, session=session).data
# <Author(name='Chuck Paluhniuk')>
