node.js - Sequelize, convert entity to plain object

Question

I'm not very familiar with javascript, and stunning, because i can't add new property, to object, that fetched from database using ORM names Sequelize.js.

To avoid this, i use this hack:

db.Sensors.findAll({
    where: {
        nodeid: node.nodeid
    }
}).success(function (sensors) {
        var nodedata = JSON.parse(JSON.stringify(node)); // this is my trick
        nodedata.sensors = sensors;
        nodesensors.push(nodedata);
        response.json(nodesensors);
});

So, what normally way to add new properties to object.

If it can help, i use sequelize-postgres version 2.0.x.

upd. console.log(node):

{ dataValues: 
   { nodeid: 'NodeId',
     name: 'NameHere',
     altname: 'Test9',

I think next, what you think will be: "Ok, that is easy, just add your property to dataValues."

node.selectedValues.sensors = sensors;
node.dataValues.sensors = sensors;

I add this lines, and this don't work

Answer 1

you can use the query options {raw: true} to return the raw result. Your query should like follows:

db.Sensors.findAll({
  where: {
    nodeid: node.nodeid
  },
  raw: true,
})

also if you have associations with include that gets flattened. So, we can use another parameter nest:true

db.Sensors.findAll({
  where: {
    nodeid: node.nodeid
  },
  raw: true,
  nest: true,
})
