rebecca.repository

An implementation of repository pattern for SQLAlchemy.

Getting Started

install by pip:

$ pip install rebecca.repository

Implement your model by SQLAlchemy:

from sqlalchemy import Column, Integer, Unicode
from sqlalchemy.ext.declarative import declarative_base

Base = declarative_base()
DBSession = scoped_session(sessionmaker())

class Person(Base):
    __tablename__ = "person"
    id = Column(Integer, primary_key=True)
    name = Column(Unicode(255))
    age = Column(Integer, default=0)

Get repository:

from rebecca.repository.sqla import SQLARepository

person_repository = SQALRepository(Person, Person.id, DBSession())

this repository for Person model. To get person, use Person.id as key.

basic dict interface

create object for demonstration:

person1 = Person(name=u"person1")
DBSession.add(person1)
DBSession.flush() # to generate person.id

A repository has dict like interface:

person_repository[person.id]
person_repository.get(person.id)

conditional repository

repository can configure to set condition:

person_repository = SQALRepository(Person, Person.id, DBSession(), condition=Person.age>30)
