+SQLAlchemy
+----------
+
+.. currentmodule:: factory.alchemy
+
+
+Factoy_boy also supports `SQLAlchemy`_ models through the :class:`SQLAlchemyModelFactory` class.
+
+To work, this class needs an `SQLAlchemy`_ session object affected to "FACTORY_SESSION" class attribute.
+
+.. _SQLAlchemy: http://www.sqlalchemy.org/
+
+.. class:: SQLAlchemyModelFactory(factory.Factory)
+
+ Dedicated class for `SQLAlchemy`_ models.
+
+ This class provides the following features:
+
+ * :func:`~factory.Factory.create()` uses :meth:`sqlalchemy.orm.session.Session.add`
+ * :func:`~factory.Factory._setup_next_sequence()` selects the next unused primary key value
+
+ .. attribute:: FACTORY_SESSION
+
+ Fields whose SQLAlchemy session object are passed will be used to communicate with the database
+
+A (very) simple exemple:
+
+.. code-block:: python
+
+ from sqlalchemy import Column, Integer, Unicode, create_engine
+ from sqlalchemy.ext.declarative import declarative_base
+ from sqlalchemy.orm import scoped_session, sessionmaker
+
+ session = scoped_session(sessionmaker())
+ engine = create_engine('sqlite://')
+ session.configure(bind=engine)
+ Base = declarative_base()
+
+
+ class User(Base):
+ """ A SQLAlchemy simple model class who represents a user """
+ __tablename__ = 'UserTable'
+
+ id = Column(Integer(), primary_key=True)
+ name = Column(Unicode(20))
+
+ Base.metadata.create_all(engine)
+
+
+ class UserFactory(SQLAlchemyModelFactory):
+ FACTORY_FOR = User
+ FACTORY_SESSION = session # the SQLAlchemy session object
+
+ id = factory.Sequence(lambda n: n)
+ name = factory.Sequence(lambda n: u'User %d' % n)
+
+.. code-block:: pycon
+
+ >>> session.query(User).all()
+ []
+ >>> UserFactory()
+ <User: User 1>
+ >>> session.query(User).all()
+ [<User: User 1>]
