I’ve been trying to figure this out for a while and think I finally stumbled on something that works pretty well for me, YMMV.

I just overrode the `preprocessData` function on my `App.Store` to check if the data I’m supplying is a full item or partial, based on the attribute `basicInfo`, then checks to see if the item is already in the Store, and returns accordningly Here’s what my `App.Store` looks like now

```
App.Store = DS.Store.extend(
  revision: 12

  preprocessData: (type, data) ->

    if data.basic_info && this.hasReferenceForId(type, data.id)
      return unless this.find(type, data.id).get('basicInfo')

    @_super(type, data)

)

```
