how query fild fields form two table when I use hasOne ?

[hacke2]

I had use hasOne get Pet,e.g:

Animal.hasOne('owner', Person, {reverse: 'pets'})
Person(1).getPets(function(err, pets) {
            console.log(pets);
});

I want through one sql query Animal's fields, can I ?

like this sql:

SELECT person.name, animal.name FROM Person as person, Animal as animal WHERE animal.owner_id = person.id
