Hi @valscion,
While testing the v1.0.0.alpha1 release on our app, I got a failing test on the AuthorizingProcessor#related_models_with_context on line 280.
Basically if assoc_value is not an Hash or an Array then assoc_value[:id] should not be used, but rather assoc_value instead. Which would give (and make my test pass):
resource_class.find_by_key(assoc_value, context: context)._model
What do you think? Could you fix that one directly one master or should I submit a PR with a spec?
