Loading data that isnt on the route? - ember.js

Question

I have a dropdown setup on a form but how do i set it up if my data isnt in the route? I am trying to load in a list of territories on a new dealer form. I have added ember-power-select add on but I cant figure out how to load the data to the add on to display the available options. Do I need to create a service or controller?
New to ember just trying to work through the basics.
Router.map(function() {
this.route('login');
this.route('admin', function() {
this.route('territory', function() {
this.route('new');
this.route('edit', { path: '/:territory_id/edit'});
this.route('view', { path: '/:territory_id/view'});
});
this.route('dealer', function() {
this.route('view', { path: '/:dealer_id/view'});
this.route('new');
});
});
});
This is my form I am using on creating a new item.
<div class="well">
<form class="form-horizontal">
<fieldset>
<legend>New Dealer</legend>
<div class="form-group">
<label for="inputFirstName" class="col-lg-2 control-label">Name</label>
<div class="col-lg-4">
{{input type="text" value=model.dealerName class="form-control" placeholder="Dealer Name"}}
</div>
</div>
<div class="form-group">
<label for="inputFirstName" class="col-lg-2 control-label">Territory</label>
<div class="col-lg-4">
{{#power-select selected=dealer options=dealer onchange=(action "chooseDestination") as |dealer|}}
{{dealer.dealerName}}
{{/power-select}}
</div>
</div>
<div class="form-group">
<div class="col-lg-10 col-lg-offset-2">
{{#link-to 'admin.dealer' class="btn btn-default"}}Cancel{{/link-to}}
<button type="submit" class="btn btn-primary" {{action 'saveDealer' model}}>Submit</button>
</div>
</div>
</fieldset>
</form>
</div>

Just because a route is the new action for a territory or the view action for a dealer, doesn't mean that you can't load other data there.
For example, in the territory/view route, you could load all the dealers.
import Ember from 'ember';
export default Ember.Route.extend({
model(params) {
return Ember.RSVP.hash({
territory: this.store.find('territory', params.territory_id),
dealers: this.store.findAll('dealer')
})
}
});
Then in your controller and templates, you would have access to model.territory and model.dealers
