How can I load a model and immediately have access to it

Say that when I load the page I include a json hash of the current user's
info
in an injection I load the info:
user_data = JSON.parse(user_json)
App.Model.load(user_data['id'], user_data)
container.typeInjection('controller', 'currentUser',
'controller:currentUser')
App.set('currentUserController', controller)
But I'd like to set the value of that currentUserController right here as
well - App.Model.load doesn't return the actual model instance!
to get it, I need to run App.Model.find(user_data['id']) and because this
is done at start up, it seems that ember-model always ends up querying the
database for this model rather than using the json I've preloaded.
Because I use this model in the startup of my app I can't defer the
loading - how can I get access to the loaded model without needing to do
an ajax request?
