How to pass Model route name item to linkTo in template in ember.js - ember.js

Question

How do I pass a route name to a {{linkTo}} dynamically?
For example, given this code:
App.Router.map(function() {
this.resource('anon', {path: '/main'},
function() {
this.route('home', {path:'/home'});
this.route('about', { path: '/about' });
this.route('contact', { path: '/contact' });
});
});
App.NavController = Ember.ArrayController.extend({
selectedNav:'',
setNav:function(value){
var nav = App.Nav.find(value);
var items = nav.get('navItems');
this.set('content', items);
}
});
these templates:
<script type="text/x-handlebars" data-template-name="nav">
<ul class="nav">
{{#each in controller}}
{{ partial "basicNav"}}
{{/each}}
</ul>
</script>
<script type="text/x-handlebars" data-template-name="_basicNav">
<li>{{#linkTo navItemPath}}{{navItemName}}{{/linkTo}}</li>
</script>
and these models with the following fixture data:
App.Nav = DS.Model.extend({
navItems:DS.hasMany('App.NavItem'),
name:DS.attr('string')
});
App.NavItem = DS.Model.extend({
nav:DS.belongsTo('App.Nav'),
navItemName:DS.attr('string'),
navItemPath:DS.attr('string')
});
App.Nav.FIXTURES = [
{
id: 10,
name: 'Anon',
navItems: [100,200,300]
}
];
App.NavItem.FIXTURES = [
{
id:100,
nav:10,
navItemName:'Home',
navItemPath:'anon.home'
},
{
id:200,
nav:10,
navItemName:'Contact',
navItemPath:'anon.contact'
},
{
id:300,
nav:10,
navItemName:'About',
navItemPath:'anon.about'
}
];
How do I pass navItemPath to the {{linkTo}} helper? In this code snippet:
{{#linkTo navItemPath}}{{navItemName}}{{/linkTo}}
ember complains that it can't find the "navItemPath" route, like it's looking for it literally. If I replace that with a valid literal route like:
{{#linkTo 'anon.home'}}{{navItemName}}{{/linkTo}}
ember will render the linkTo with the navItemName as expected, so I know the controller is passing it the right data, but of course all the routes are goofy. Am I missing something obvious?

Answer 1

You can't do that with LinkTo helper, you need to bind the href of your link to navItemPath using bindAttr
<a {{bindAttr href="navItemPath"}}>{{navItemName}}</a>
Make sure the the logic rending navItemPath's value takes into account the location API
