Ember.js Fixture findQuery - ember.js

Question

I'm trying to change my URLs in Ember to use a property on a model (title), instead of the ID. I can get everything to work if I click on a link-to, but when I do a fresh reload of the models route, everything seems to fall apart. Within queryFixtures I can get return the desired item, and logs to the console by logging 'experiment' to the console in the model hook.
App.ExperimentRoute = Ember.Route.extend({
serialize: function(experiment, params) {
return {
experiment_title: experiment.get('urlFriendlyName')
}
},
model : function(params) {
experiment = this.get('store').find('experiment', { title: params.experiment_title });
return experiment;
}
});
My store:
App.Store = DS.Store.extend({
adapter: DS.FixtureAdapter.extend({
queryFixtures: function(fixtures, query, type) {
function urlFriendlyTitle(title) {
var ret = title.replace(/ /g,"-"); // replace spaces
// do other replacements that make sense in your case, e.g.:
ret = ret.replace(/&/g,"and");
//... and so on and so forth
// encode the remaining characters
ret = ret.toLowerCase();
ret = encodeURIComponent(ret);
return ret;
}
return fixtures.filter(function(item) {
if(urlFriendlyTitle(item.title) == query.title) {
// console.log(item);
return item;
}
});
}
})
});
UPDATE:
App.ExperimentRoute = Ember.Route.extend({
model : function(params) {
experiment = this.get('store').find('experiment', { });
console.log(Ember.inspect(experiment))
return experiment;
}
});
Running the above outputs '<DS.PromiseArray:ember325>' in the console
App.Router.map(function () {
// Add your routes here
this.resource('category', { path: '/:category_id'}, function() {
this.resource('experiment', { path: '/:experiment_title' }, function() {
this.resource('device', { path: '/:device' });
});
});
});
App.ExperimentRoute = Ember.Route.extend({
setupController: function(controller, model) {
console.log(Ember.inspect(model))
console.log(Ember.inspect(controller))
}
})
This route outputs <App.ExperimentController:ember388> <DS.AdapterPopulatedRecordArray:ember326>
