nathanjsharpe / AssetStore.js
Created October 29, 2015 19:22
Merge and sync
// assets param is either a plain js object or an array of plain js objects
_merge(assets) {
// If parameter is a single object, make it an array
assets = Array.isArray(assets) ? assets : [assets];
// From object(s), create an ordered map of id => record
let newAssets = new OrderedMap(assets.map(asset => [asset.id, new Asset(asset)]));
// Merge in new assets, keeping old if new is equal (same values) to preserve reference equality
this._assets = this._assets.mergeWith((prev, next) => prev.equals(next) ? prev : next, newAssets);

rather than specify the association using has_one or belongs_to, you can define it yourself
class PlaceSerializer < ActiveModel::Serializer
attributes :id, :foo, :bar, :features
def features
feature
end
