The `created` column is handled through a default and the `updated` column is handled through a `before_update` event that propagates for all derived declarative models. :: import sqlalchemy as sa from sqlalchemy_utils import Timestamp class SomeModel(Base, Timestamp): __tablename__ = 'somemodel' id = sa.Column(sa.Integer, primary_key=True) cjtjtjj dSN)tz)tzinfornowrutcreplaceZ/home/azureuser/techstart-app/venv/lib/python3.12/site-packages/sqlalchemy_utils/models.pyzTimestamp.!  5==T=JrF)defaultnullablecjtjtjj dSrr rrrrzTimestamp. rrN) __name__ __module__ __qualname____doc__saColumnDateTimecreatedupdatedrrrrrsE$bii JG bii JGrr before_updateT) propagatecvtjtjj d|_yr)rr rr rr)mapper connectiontargets rtimestamp_before_updater&%s&\\X\\2::$:GFNrz ctj|}g}|s$|jjj }|D]]}|j |j }||jvrt}n t|}|jdj||f_dj|jjdj|S)N=z{}({})z, )rinspectr#columnskeysattrs loaded_valueunloadedNOT_LOADED_REPRreprappendjoinformat __class__r)selffieldsstate field_reprskeyvalues r_generic_repr_methodr;/s JJt EK %%**,3 C -- %.. #EKE388S%L12 3 ??4>>22DIIk4J KKrchtdk(rtdrd}d|_|Sfd}|S)aAdds generic ``__repr__()`` method to a declarative SQLAlchemy model. In case if some fields are not loaded from a database, it doesn't force their loading and instead repesents them as ````. In addition, user can provide field names as arguments to the decorator to specify what fields should present in the string representation and in what order. Example:: import sqlalchemy as sa from sqlalchemy_utils import generic_repr @generic_repr class MyModel(Base): __tablename__ = 'mymodel' id = sa.Column(sa.Integer, primary_key=True) name = sa.Column(sa.String) category = sa.Column(sa.String) session.add(MyModel(name='Foo', category='Bar')) session.commit() foo = session.query(MyModel).options(sa.orm.defer('category')).one(s) assert repr(foo) == 'MyModel(id=1, name='Foo', category=)' rct|dSN)r6r;)r5s rrzgeneric_repr.._s';D'Nrcfd|_|S)Nct|Sr?r@)r5r6s rrz1generic_repr..decorator..ds(.decoratorcsQCLJr)lencallablerC)r6r%rEs` r generic_reprrH?s>< 6{aHVAY/N  r) rr sqlalchemyrrevent listens_forr&r/r;rHrrrrLsT'>iDAHBH !
