Using my Rails app API for iPhone App - iphone

Question

I'm learning iOS Development with the Treehouse Library. Building an app that gets information from a json API.
In the Treehouse API page all the posts are under a parent called "Posts" (http://blog.teamtreehouse.com/api/get_recent_summary/)
posts: [
{
id: 22198,
url: "http://blog.teamtreehouse.com/using-github-pages-to-host-your-website",
title: "Using GitHub Pages To Host Your Website",
date: "2013-08-16 09:30:20",

},

},
The API from my Rails app doesnt have a Parent (http://www.soleresource.com/releases.json)
[
{
shoe_name: "Air Jordan 4 "Green Glow"",
release_date: "2013-08-17T00:00:00.000Z",
shoe_colorway: "Dark-Grey/Green-Glow",
shoe_price: "160",
url: "http://www.soleresource.com/releases/8.json"
},
{
shoe_name: "Nike Barkley Posite",
release_date: "2013-08-17T00:00:00.000Z",
shoe_colorway: "Gamma-Green/Black",
shoe_price: "235",
url: "http://www.soleresource.com/releases/17.json"
},
In order to get the app to work I have to call the Parent (posts), like this:
self.upcomingReleases = [dataDictionary objectForKey:#"posts"];
How can I "wrap" my API under a Parent? (My model is called "Releases")

IMHO, if you are using your rails app as a REST API, you should definitely use ActiveModel::Serializer. It will let you specify everything for your JSON responses, like metadata or roots
Here is a RailsCast for it: http://railscasts.com/episodes/409-active-model-serializers
