ember data custom serializer for a json - json

Question

I have a Session object I want to model in Ember data. (actually display sessions but it's the same)
The JSON from the server looks like this (cannot be changed):
{
"metadata": {
"page": 1,
"page_size": 100,
"total_num_objects": 7,
"total_num_pages": 1
},
"result": [
{
"api_path": "/rest/sessions/2",
"end_time": 1412687629.42063,
"hostname": "127.0.0.1",
"id": 2,
"logical_id": "c6656738-4e23-11e4-9017-685b35b63131_0",
"product_name": null,
"product_revision": null,
"product_version": null,
"start_time": 1412687629.26851,
"status": "SUCCESS",
"type": "session",
"user_name": null
},
{
"api_path": "/rest/sessions/3",
"end_time": 1412688377.15329,
"hostname": "127.0.0.1",
"id": 3,
"logical_id": "84707366-4e25-11e4-a659-685b35b63131_0",
"product_name": null,
"product_revision": null,
"product_version": null,
"start_time": 1412688377.11507,
"status": "SUCCESS",
"type": "session",
"user_name": null
},
...
I realize I need to write a custom RESTSerializer but I can't figure out what do I need to do in order go get rid of metadata + make ember realize that result is actually a session.
Side question:
Can I make the DS.Model.extend attributes like what I get from the API or do I must use CamelCase and use normalizeHash

Answer 1

You'd probably need to do something like this:
App.SessionSerializer = DS.RESTSerializer.extend({
normalizePayload: function(payload) {
return {
sessions: payload.result
};
}
});
See: http://emberjs.com/api/data/classes/DS.RESTSerializer.html#method_normalizePayload
Regarding your other issue, look at DS.ActiveModelAdapter / ActiveModelSerializer. ActiveModelSerializer handles the underscore convention in the JSON.
