ember-data: How to tell if a model's async: true relationship is loaded without triggering a load?

Question

I need to check if an async relationship has been loaded without triggering the load, is this possible?

Answer 1

There is no official way to accomplish this yet, but unofficially you can do

// this will be null if not loaded, and populated if it has at least started loading
if(model._relationships.yourRelationshipName) {...}
