Sequelize - update record, and return result

Question

I am using sequelize with MySQL. For example if I do:

models.People.update({OwnerId: peopleInfo.newuser},
        {where: {id: peopleInfo.scenario.id}})

Here's what I think you're looking for.

db.connections.update({
  user: data.username,
  chatroomID: data.chatroomID
}, {
  where: { socketID: socket.id },
  returning: true,
  plain: true
})
.then(function (result) {
  console.log(result);   
  // result = [x] or [x, y]
  // [x] if you're not using Postgres
  // [x, y] if you are using Postgres
});

From Sequelize docs: The promise returns an array with one or two elements. The first element x is always the number of affected rows, while the second element y is the actual affected rows (only supported in postgres with options.returning set to true.)

Assuming you are using Postgres, you can access the updated object with result[1].dataValues.

You must set returning: true option to tell Sequelize to return the object. And plain: true is just to return the object itself and not the other messy meta data that might not be useful.
