How can I create a repeating element from data received from <iron-ajax>?
Question
<iron-ajax auto
url='http://api.fantasy.nfl.com/v1/players/stats'
handle-as="json"
last-response="{{response}}"></iron-ajax>
<template is="dom-repeat" items="{{response}}">
<paper-material class="add-players">
<div class="layout horizontal center">
<h2>{{item.players.name}}</h2> //NOT SURE WHAT SYNTAX SHOULD BE
</div>
</paper-material>
</template>
I am using to return a response from a public API. The problem I have is that the API returns an object and Polymer does not allow us to do a dom-repeat over an object. I am really trying to access an array within that object, is there some way to extract that array from the object returned and do a dom-repeat over that array? If not is there another solution to accessing the response from polymer? Thank you!

You have to use {{response.players}} instead of {{response}} in the dom-repeat . Here is a working demo.
