Ember extractors for REST when backend returns data wrapped in "data" object, not in model name and "pagination" as a payload field

store.coffee

App.Store = DS.Store.extend
    revision: 1,
    adapter: DS.RESTAdapter.extend
        namespace: 'api'

App.ApplicationSerializer = DS.RESTSerializer.extend
    extractMeta: (store, type, payload)->
            if payload && payload.pagination
                store.metaForType type, payload.pagination
                delete payload.pagination

    extractArray: (store, type, payload, id, requestType)->
        if payload && payload.data
            key = Ember.Inflector.inflector.pluralize type.typeKey
            payload[key] = payload.data
            delete payload.data
        @_super store, type, payload, id, requestType

    extractSingle: (store, type, payload, id, requestType)->
        if payload && payload.data
            key = Ember.Inflector.inflector.singularize type.typeKey
            payload[key] = payload.data
            delete payload.data
        @_super store, type, payload, id, requestType
