Ember.JS : 'serializer.get is not a function' - serialization

Question

So i'm learning EMBER JS from codeschool and i sometime like to save my current progress into my computer. Everything went nice and smoothly until we started to see Array Controller ( and by nice and smoothly i mean everything was working fine, as it does on codeschool ). Since then i got this error :
Error while processing route: index serializer.get is not a function TypeError: serializer.get is not a function

So i thought, somehow, my ember.js or ember-data.js was the culprit but nay, it's not ( im up-to-date ). I think the bug is somewhere located in the way i initialize my Route ( eventho i copy/pasted the content of my local files from those on codeschool who works perfectly ) and according to the error message, i think the index route is responsible so here is my router map :
App.Router.map(function() {
this.route('credits', { path: '/thanks' });
this.resource('products', function() {
this.resource('product', { path: '/:product_id' });
});
this.resource('contacts', function() {
this.resource('contact', { path: '/:contact_id' });
});
});
And here's my route ( they're all made like this one, except that i sometime search in 'contact' rather than 'product' )
App.IndexRoute = Ember.Route.extend({
model: function(){
return this.store.findAll('product');
}
});
We also use the fixture adapter so it might come from this too :
App.ApplicationAdapter = DS.FixtureAdapter.extend({});
Does anybody ever got this bug about the serializer ? Thank you'all in advance !

Answer 1

I believe this is due to the removal of the Fixture Adapter in a recent ember-data release. I'm just learning ember myself, but I was finally able to get rid of this error using a combination of reverting to a slightly older ember-data version and installing the replacement Fixture Adapter addon.
In your application dir, update the ember-data line in both bower.json and package.json to:
"ember-data": "1.0.0-beta.19.2",
and in package.json add this line after the ember-data one:
"ember-data-fixture-adapter": "^1.0.0",
Delete the bower_components and node_modules dirs in your application, and then run npm install and bower install from your application's home dir.
