Model 'save' cannot be used like the doc says

[ooXavier]

var user = new User('John', 'john@test.com');
user.save((err) => {
    // callback
});

This code (from the doc) does not work.
Should be written :

User.save(user, (err) => {
    // callback
});

Could you add, the orginal way in Waterline and maybe upgrade to 0.10.x as it's a little bit different from 0.9.x
