I am trying to add a property to a sequelize instance before passing it back to the client.

router.get('/cats/1', function (req, res) {

    Cat.findOne({where: {id: 1}})

        .then(function (cat) {

            // cat exists and looks like {id: 1}

            cat.name = Lincoln;

            // console.log of cat is {id: 1, name: Lincoln}

            res.json(cat);

        });

});

The client only see's {id: 1} and not the newly added key.

• What is going on here?


• What type of Object is returned by Sequelize?


• How can I add new properties to my Cats and send them back?
