getting error with ember-fire: Assertion Failed: You must include an 'id' for undefined in an object passed to 'push' - emberfire

Question

I have a sample notebook app that works with ember-cli's HTTP mocks and also my rails backend using ActiveModelSerializer.
When I hook it to firebase with ember-fire, I am able to register a user (I see it in the dashboard) but when I try to retrieve it by email, I get the following warning:
WARNING: Encountered "0" in payload, but no model was found for model name "0" (resolved model name using ui#serializer:application:.modelNameFromPayloadKey("0"))
then this error:
Error: Assertion Failed: You must include an 'id' for undefined in an object passed to 'push'
at new Error (native)

I am querying the store using:
export default Ember.Route.extend({
actions: {
login: function() {
this.store.query('user', {
email: this.controller.get('email')
}).then((users) => {
if(users.get('length') === 1) {
var user = users.objectAt(0);
this.controllerFor('application').set('user',user);
this.transitionTo('notebooks', user.get('id'));
}
else {
console.log('unexpected query result');
}
});
}
}
});
Digging in, I can see by setting breakpoint at finders.js#157 I am about to
store._adapterRun(function () {
var payload = normalizeResponseHelper(serializer, store, typeClass, adapterPayload, null, 'query');
//TODO Optimize
records = store.push(payload);
});
push the payload. The adapter payload inspects to
adapterPayload: Array[1]
0: Object
email: "test#test.com"
first_name: "Test"
id: "-K1oINClDw2ylQLww7-p"
last_name: "User"
which is my user. So all's good except for the trace. Not sure about that ID but I am new to firebase; maybe it's ok. It matches what I see in my dashboard.
I haven't done anything special with my serializer -- it's vanilla.
import DS from 'ember-data';
export default DS.RESTSerializer.extend({
});
AFAIK I am using the latest & greatest -- here's bower.json

Any pointers/help/guidance would be great! I am also new to ember too, so maybe I am missing the obvious?

Answer 1

You need a type key to be returned from your backend, rather than just sending an array. This lets Ember Data know what type of model you're pushing to the store. Your payload should look like this:
users: [
{
email: "test#test.com",
id: "abcdefg"
(...)
}
]
instead of this
[
{
email: "test#test.com",
id: "abcdefg"
(...)
}
]
Alternatively you can explicitly pass in the type and data:
store.push("user", store.normalize("user", response[0]));
(where response is still the array)
