Redirect after saving new record

I’ve tried to tweak previous similar solutions to fit my use case, but just can’t get it to work. I’m new to javascript and am probably making a silly mistake.

• I am saving a parent object (Shipment) and child objects (ShippingRecords). Once I save, I want to redirect to the the shipment (the first row in the Shipment model). The snippet below is called from a button on a page title component where the model is Shipment.

• I’ve included my entire snippet for reference, but the part I think I need help with is bolded below. I’m not sure if I’m doing the merge right, or if I need to put that piece of code elsewhere.

Thanks, as always, for the help.

var params = arguments[0], $ = skuid.$;

var models = skuid.model.map();
var ShipmentModel = models.Shipment;
var TheShipment = ShipmentModel.getFirstRow();
var shippingrecords = models.ShippingRecords;

ShipmentModel.save({callback:function(){
var Direction = TheShipment.Direction__c;
var Status = TheShipment.Status__c;
var ShipFrom = TheShipment.Ship_From__c;
var ShipTo = TheShipment.Ship_To__c;
var ShippingMethod = TheShipment.Shipping_Method__c;
var TrackingNumber = TheShipment.Tracking_Number__c;
var DateShipped = TheShipment.Date_Shipped__c;
var DateArrived = TheShipment.Date_Arrived__c;

$.each(shippingrecords.data,function(i,row){
    shippingrecords.updateRow(row,{
        Direction__c : Direction,
        Status__c : Status,
        Ship_From__c : ShipFrom,
        Ship_To__c : ShipTo,
        Shipping_Method__c : ShippingMethod,
        Tracking_Number__c : TrackingNumber,
        Date_Shipped__c : DateShipped,
        Date_Arrived__c : DateArrived
    });
});


shippingrecords.save();

var model = params.model;
var row = params.row;
var url = “/{{id}}”;
var merges = skuid.$(‘
