Add Property to Object that is returned by Sequelize FindOne

Question

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({w         


        

Answer 1

What works for me is to use setDataValue

router.get('/cats/1', function (req, res) {
    Cat.findOne({where: {id: 1}})
        .then(function (cat) {
            cat.setDataValue("name", "Lincoln");
            res.json(cat);
        });
});

Specs for the function

public setDataValue(key: string, value: any)

Update the underlying data value

Params:

Name    Type    Attribute   Description
key     string              key to set in instance data store   
value   any                 new value for given key
