Async records not automatically being fetched - ember.js

Question

I am trying to display some CI information via an ember application backed by Firebase. If I do a this.store.find('plan'); it fetches and displays the plans for the desired project, but it doesn't automatically async fetch the plans like I want. I am not quite sure what I am doing wrong.

App = Ember.Application.create();
App.Router.map(function() {
// put your routes here
});
App.IndexRoute = Ember.Route.extend({
model: function() {
return this.store.find('project');
}
});
App.ApplicationAdapter = DS.FirebaseAdapter.extend({
firebase: new Firebase('https://my.firebaseio.com/api-data/')
});
App.Project = DS.Model.extend({
name: DS.attr('string'),
plans: DS.hasMany('plan', { async: true })
});
App.Plan = DS.Model.extend({
project: DS.belongsTo('project', { async: true }),

isBuilding: DS.attr('boolean'),
averageBuildTimeInSeconds: DS.attr('number')
});
My template
<script type="text/x-handlebars" data-template-name="index">
<ul>
{{#each project in model}}
<li>
<h3>{{project.name}}</h3>
<ul>
{{#each plan in project.plans}}
<li>{{plan.name}}</li>
{{else}}
<li>no plans</li>
{{/each}}
</ul>
</li>
{{/each}}
</ul>
</script>
How can I get the ember-data async relationship to automatically fetch when I try to access the project.plans property?
Edit:
I have tried mocking with Ember-CLI's http-mock and am sending back the following for /projects
{"plans":[{id: '10', project: '1', name: 'test', plans: ['10']}]}
Which is now working with adding the plans array. I now just need to figure out how this works on firebase.

Answer 1

When using Firebase after my initial seed data, I fetched each model type and called save on all instances. This caused Firebase to be properly populated for the async data array. This was persisted as follows:
/projects
{
"AS": {
"name": "AS",
"plans": {
"AS-AS": true
}
},
"F": {
"name": "F",
"plans": {
"F-INT": true,
"F-QA": true,
"F-STAG": true
}
}
}
/plans
{
"AS-AS": {
"averageBuildTimeInSeconds": 23,
"description": "",
"enabled": true,
"isBuilding": false,
"name": "AS - AS",
"project": "AS",
"shortKey": "AS",
"shortName": "AS",
"type": "chain"
},
"F-INT": {
"averageBuildTimeInSeconds": 18,
"description": "Integration build",
"enabled": true,
"isBuilding": false,
"name": "F - Integration",
"project": "F",
"shortKey": "INT",
"shortName": "Integration",
"type": "chain"
},
"F-QA": {
"averageBuildTimeInSeconds": 38,
"description": "Release from Stage to QA",
"enabled": true,
"isBuilding": false,
"name": "F - QA",
"project": "F",
"shortKey": "QA",
"shortName": "QA",
"type": "chain"
},
"F-STAG": {
"averageBuildTimeInSeconds": 16,
"description": "Stage Build and Deploy",
"enabled": true,
"isBuilding": false,
"name": "F - Stage",
"project": "F",
"shortKey": "STAG",
"shortName": "Stage",
"type": "chain"
}
}
