Invalid fullName: `model:@each`, must be of the form `type:name`

Question

I'm setting up a new app with Ember CLI and a Rails backend following this tutorial but when I set up a route for one of my models, I get the following error:

Error while processing route: inks.index Invalid fullName: `model:@each`, must be of the form `type:name`  TypeError: Invalid fullName: `model:@each`, must be of the form `type:name`

I've googled around, but I have no idea what it even means. I've checked to make sure I have ActiveModelAdapter and Serializer. The model is not complicated:

My route is app/routes/users/index.js:

import Ember from 'ember';

export default Ember.Route.extend({
 model: function() {
    return this.store.find('user'); 
 }
});

app/router.js:

import Ember from 'ember';
import config from './config/environment';

var Router = Ember.Router.extend({
  location: config.locationType
});

Router.map(function() {
  this.resource('users');
});
export default Router;

and my app/adapters/application.js is:

import DS from 'ember-data';

export default DS.ActiveModelAdapter.extend({
    namespace: 'api/v1'
});

I'm still pretty new with EmberCLI so i'm not really sure where to look.

I stuck with similar issue. Only one difference I was used rabl.

The problem was with my rabl configuration:

Rabl.configure do |config|
  config.include_json_root = false
end

Ember.js documentation tells us:

The JSON payload should be an object that contains the record inside a root property

So, you need to change rabl configuration to:

Rabl.configure do |config|
  config.include_json_root = true
end

or, pass root option inside rabl template:

collection @orders, root: 'orders'

So it turns out I wasn't using ActiveModelSerializers correctly. Since I was listing all users as a test I thought it would serialize as a list of the serialized data I defined in UserSerializer.

I was doing this in my controller:

def index
  @users = User.all
  render json: @users
end

When I SHOULD have been doing this according to the docs (here):

def index
  @users = User.all
  render json: @users, each_serializer: UserSerializer
end

I didn't even notice my serializer wasn't being called.
