Base with a `model_id` property for SQLAlchemy models

Project description

SQLAlchemy-ModelID provides a base for SQLAlchemy models with a model_id property. This conveniently distinguishes between models with the same primary key but from different tables.


$ pip install sqlalchemy-modelid


from sqlalchemy_modelid import ModelIdBase

# standard session creation
from sqlalchemy import create_engine, Column, Integer
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy.orm import sessionmaker, scoped_session

engine = create_engine('sqlite:///:memory:')
session_factory = sessionmaker(bind=engine)
Session = scoped_session(session_factory)
session = Session()
Base = declarative_base()

# subclass `ModelIdBase` to add a `model_id` property to any model
class Model(ModelIdBase, Base):
    __tablename__ = 'model'
    id = Column(Integer, primary_key=True)

# create the database

# example
my_model = Model()
