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) F)defaultnullableN) __name__ __module__ __qualname____firstlineno____doc__saColumnDateTimerutcnowcreatedupdated__static_attributes__r =/venv/lib/python3.13/site-packages/sqlalchemy_utils/models.pyrrs=$ii X__uMGii X__uMGrr before_updateT) propagatec8[R"5Ulg)N)rrr)mapper connectiontargets rtimestamp_before_updaters__&FNrz c[R"U5n/nU(d$URRR 5nUH^nUR UR nXBR;a[nO [U5nURSRXE455 M` SRURRSRU55$)N=z{}({})z, )rinspectrcolumnskeysattrs loaded_valueunloadedNOT_LOADED_REPRreprappendjoinformat __class__r )selffieldsstate field_reprskeyvalues r_generic_repr_methodr3's JJt EK %%**, C -- .. #EKE388SL12  ??4>>22DIIk4J KKrcv^[T5S:Xa"[TS5(aTSnSUlU$U4SjnU$)atAdds generic ``__repr__()`` method to a declarative SQLAlchemy model. In case if some fields are not loaded from a database, it doesn't force their loading and instead repesents them as ````. In addition, user can provide field names as arguments to the decorator to specify what fields should present in the string representation and in what order. Example:: import sqlalchemy as sa from sqlalchemy_utils import generic_repr @generic_repr class MyModel(Base): __tablename__ = 'mymodel' id = sa.Column(sa.Integer, primary_key=True) name = sa.Column(sa.String) category = sa.Column(sa.String) session.add(MyModel(name='Foo', category='Bar')) session.commit() foo = session.query(MyModel).options(sa.orm.defer('category')).one(s) assert repr(foo) == 'MyModel(id=1, name='Foo', category=)' rc[USS9$N)r.r3)r-s rgeneric_repr..Ws ';D'Nrc>U4SjUlU$)Nc>[UTS9$r7r8)r-r.s rr91generic_repr..decorator..[s(<)r)__repr__)clsr.s r decoratorgeneric_repr..decoratorZsCLJr)lencallabler>)r.rr@s` r generic_reprrD7sA< 6{aHVAY//N   r) r sqlalchemyrrevent listens_forrr'r3rDr rrrHsTNN.iDA'B' !
