attrs-sqlalchemy 0.1.0

Add dunder-methods to SQLAlchemy models with attrs

Use attrs to add __repr__, __eq__, __cmp__, and __hash__ methods according to the fields on a SQLAlchemy model class.

from attrs_sqlalchemy import attrs_sqlalchemy

@attrs_sqlalchemy
class MyModel(Base):
    __tablename__ = 'mymodel'

    id = sa.Column(Integer, primary_key=True)
    text = sa.Column(sa.String)

instance = MyModel(id=1, text='hello')
same_data = MyModel(id=1, text='hello')
same_pk = MyModel(id=1, text='world')

assert instance == same_data
assert instance != same_pk
assert repr(instance) == "MyModel(id=1, text='hello')"
