defernia.orm — Object-relational mapping powered by SQLAlchemy

This module provides object-relational mapping facilities powered by SQLAlchemy.

In order to define persist model class, just subclass Base:

from sqlalchemy import *
import defernia.orm


class Thing(defernia.orm.Base):
    '''A something object-relationally mapped.'''

    id = Column(Integer, primary_key=True)
    value = Column(UnicodeText, nullable=False)
    __tablename__ = 'things'

defernia.orm.Session = sessionmaker(class_='Session'autoflush=True, bind=None, autocommit=True, expire_on_commit=True)

SQLAlchemy session class.
