What is the best way to modify the date format when ember-data does serialization?

Question

In my ember-data adapter I use this line to serialize my model

var data  = record.serialize();

But I've noticed my models with a date type ...

App.Foo = DS.Model.extend({
    start: DS.attr('date')
});

... will post the date like this to my REST api

Sat, 02 Mar 2013 22:15:00 GMT

But I need something more api friendly such as yyyy-mm-dd or mm/dd/yyyy

Does ember-data offer a hook to change how dates are sent over the wire?

I would assume not as this is the actual return line from the serialize method in ember-data rev 11

return dayOfWeek + ", " + dayOfMonth + " " + month + " " + utcYear + " " + pad(utcHours) + ":" + pad(utcMinutes) + ":" + pad(utcSeconds) + " GMT";

Update

I also opened an issue on ember-data to see why this format was chosen to begin with

Answer 1

You could register a custom serializer transform

DS.RESTAdapter.registerTransform("isodate", {
  deserialize: function(serialized) {
    return serialized;
  },

  serialize: function(deserialized) {
    return deserialized;
  }
});

and then just use it as start: DS.attr("isodate"), with proper definitions of serialize/deserialize of course :)
