Ember.js - Not sure how to model data

I'm using the RESTAdapter from Ember data to work with a JSON payload. Part of the payload contains data such as

"links": {
    "facebook": "http://ift.tt/1FocBDV",
    "twitter": "http://ift.tt/VisB5f",
    "officialWebsite": "http://ift.tt/q88H9a"
},

I'm not really sure how to model the data. I noticed that the RESTSerializer has a normalizePayload function, so I figured I'd give that a shot instead of the RESTAdapter. I used it like so

normalizePayload: function(payload) {
    payload.facebookUrl = payload.links.facebook;
    payload.twitterUrl = payload.links.twitter;
    payload.mySpaceUrl = payload.links.myspace;
    payload.officialWebsiteUrl = payload.links.officialWebsite;
    delete payload.links;
    return payload;
}

Problem with this approach is the RESTSerializer doesn't support the findQuery method, which I rely on. I get an error saying tried to load a query but your adapter does not implement findQuery

Any help on this would be greatly appreciated.
