Ember.js ember-data and cross-domain ajax requests

folks! Any examples of using ember-data to store data getted from remote server with cross-domain ajax request? Now I have this, but...

TravelClient.Tour = Ember.Object.extend({
});

TravelClient.Tour.reopenClass({
  allTours: [],
  find: function(){
    $.ajax({
      url: 'http://someIP:somePORT/tours.json',
      dataType: 'jsonp',
      context: this,
      success: function(data){
        data.forEach(function(tour){
          this.allTours.addObject(TravelClient.Tour.create(tour))
        }, this)
      }
    })
    return this.allTours;
  }
});

UPDATE: Now i'm doing it in this way:

TravelClient.Tour.reopenClass({
  allTours: [],
  find: function(){
    $.ajax({
      url: 'http://someIP:somePORT/tours.json',
      dataType: 'jsonp',
      context: this,
      success: function(response){
        response.data.forEach(function(tour){
          this.allTours.addObject(TravelClient.Tour.create(tour))
        }, this)
      }
    })
    return this.allTours;
  }
});

But get this error:

Uncaught TypeError: Cannot call method 'forEach' of undefined

SNAPSHOT:

with this:

$.ajax({
  dataType: 'jsonp',
  url:"http://192.168.1.39:3000/tours.json",
  success:function(response){
    return response.data;
  }
});

I get this:

This is more a about how the server should return data to the client than about ember-data, what you need to do is, wrap the response to the ajax call in a callback whose value is sent as a parameter to the server. Once you do that, it's business as usual for ember-data i.e quite transparent to it

Here's an example using ruby on rails

On the client side

$.ajax({
    dataType: 'jsonp',
    success: function(response) {
       // loop through your objects
       response.accounts.forEach(function(account){
          console.info(account.id)
       })
    }
});

On the server side you should do something similar to 

params[:callback] + '("' + response + '");';

Yielding for example a response similar to: 

callbackValue00923411(
    {
        "accounts":
        [
            {
                "id": 123,
                "name": "Personal",
            },
            {
                "id": 234,
                "name": "Corporate",
            }
        ]
    }
);

Then in your success function you access the list of accounts, as I stated above, this way 

success: function(response) {
   // loop through your objects
   response.accounts.forEach(function(account){
      console.info(account.id)
   })
}

Here's an example on how to use/handle jsonp ajax request

If you have access to the server, you may consider configuring it to use CORS instead and avoid using jsonp
