Child belongsTo Father, then Father belongsTo GrandFather issue..

[feitian124]

suppose i have 3 model Child, Father, GrandFather, and previous one belongsTo latter one.

When i unit test those models,

import { moduleForModel, test } from 'ember-qunit';
import Ember from "ember";

moduleForModel('child', 'Child', {
  needs: ['model:father']
});

test('it exists', function() {
  var model = this.subject({
  });
  // var store = this.store();
  ok(!!model);
});

it always report error like "can not find model GrandFather".
I did not write anything related to setup and teardown, just use ember-cli generated default code, where am i wrong? do i need write setup and teardown in all of them? and how?

You have to specify all of the classes that your model requires in needs. Something like:

moduleForModel('child', 'Child', {
  needs: ['model:father', 'model:grandfather']
});

@rwjblue i don't know if model:after and model:grandfather yet go through the correct model factory. Although you guys may have fixed this problem already...

the problem solved as per @rwjblue suggestion, thanks.
It is a little confusing however.
In my case the dependence chain is quite simple;In real case, it is very likely a model have multi-dependence and each dependence have other dependence, it is not a good idea needs all those models for testing, and that is why i thought it only needs direct dependence when at first.

@feitian124 that is why the discussion that @stefanpenner linked to in #108 is relevant
