Where/when should I remove the relationship type to avoid an unknown keys warning? - ember.js

Question

I'm using Ember Data with a server application that follows the json:api standard. When I normalize the response from the server, I'm adding a relationshipType attribute from the links so that Ember Data knows what type of model to build when the relationship is polymorphic.
For example, here's the response from the server:
{
"members": {
"id": "1",
"created_at": "2014-10-15T18:35:00.000Z",
"updated_at": "2014-10-15T18:35:00.000Z",
"links": {
"user": {
"id": "1",
"type": "users",
"href": "http://test.host/api/v1/users/1"
},
"organization": {
"id": "2",
"type": "customers",
"href": "http://test.host/api/v1/customers/2"
}
}
}
}
The organization relationship is polymorphic, and the type in this instance is customers.
In the Ember application, I'm normalizing the response into following (which follows the RESTSerializer convention):
{
"members": {
"id": "1",
"created_at": "2014-10-15T18:35:00.000Z",
"updated_at": "2014-10-15T18:35:00.000Z",
"user": "1",
"userType": "users",
"organization": "2",
"organizationType": "customers"
}
}
This works, and Ember Data builds the correct user relationship and organization relationship (using the Customer model).
But, I'm receiving the following warning:
WARNING: The payload for '(subclass of DS.Model)' contains these unknown keys:
[userType,organizationType]. Make sure they've been defined in your model.
I'd like to remove these relationshipType keys and their values after they've been used.
Where should I do this?

Have you tried using https://github.com/kurko/ember-json-api? I may have some other overrides in my app to handle polymorphism but hopefully the package will get you closer.
