Emberjs - RESTful Resource Processing

I am trying to load sample data from a REST API source that returns XML inside my emberjs application, but I am having two problems:

• The model name is always in the plural, so instead of / sqlrest / CUSTOMER / 3 /, the code always generates / sqlrest / CUSTOMERS / 3 /

• I know that DS.RESTAdaptor expects JSON format by default, so I was wondering if there is a way to get the XML format and can be converted to JSON?

thank

The code I use is as follows (this code, which I found in one of the SO answers and modified to match the URL I'm trying to get):

App.store = DS.Store.create({
    revision: 11,
    adapter: DS.RESTAdapter.create({
        namespace: "sqlrest",
        url: "http://www.thomas-bayer.com",
        plurals: {
            'customer': 'customer'
        },
        ajax: function (url, type, hash) {
            hash.url = url;
            hash.type = type;
            hash.dataType = 'jsonp';
            hash.contentType = 'application/json; charset=utf-8';
            hash.context = this;

            if (hash.data && type !== 'GET') {
                hash.data = JSON.stringify(hash.data);
            }

            jQuery.ajax(hash);
        },
    })
});

and on the way:

App.CustomersRoute = Ember.Route.extend({
  model: function() {
    //return App.Customer.find();
    //New
    return App.Customer.find(18);
  }
});
