Hi all !
when defining a class (derived from Base), when is recommended to define
the __init__() method ? I know this consideration https://goo.gl/2umBJv,
but I can't see the diference when creating objects for database
population. It seems __init_() is never required.
Thanks !

making some assumptions about your Table objects, your query above
would look something
the following query...
session.query(Comune).options(eagerload('provincia')).select(and_(Provincia.c.nome=='MODENA',Provincia.c.codice==Comune.c.cod_provincia),order_by=Provincia.c.nome,

I see this examples works only with table object.
