//Still learning models... I'm wondering if this can be written better.
// This link explains how to cache the results to save on API calls...

var Posts = can.Model.extend({
    findAll: 'GET https://myblog.firebaseio.com/website/posts.json',
    makeFindAll: function( findAllData ){
      var self = this;
      return function(params, success, error){
        return findAllData(params).then(function(data){
            return self.models({data:data})
          });
      }
    }
  },{});
