Emberjs: Create a complex action with data from parent and child

Emberjs: Create a complex action with data from parent and child

So I have this ember app I am building and everything has gone smoothly
until now. I am in a bit of a jam and can't quite understand what I have
to do, but I know what I want to do. The place where I am stuck is this: I
want to display all the recordings for a user, and for each recording
there will be 1 or 2 filtered versions (maybe more later). In the table
that displays all a users recordings, I want to render a link for each
version. Currently we form those links in the API by prepending something
to the public id for the recording.
So here is some pseudocode to help illustrate what I am asking about:
//models
App.User = DS.model.extend({
first_name: DS.attr('string'),
last_name: DS.attr('string')
recordings: DS.hasMany(App.Recording)
});
App.Recording = DS.model.extend({
name: DS.attr('string'),
filter: DS.hasMany(App.Filter)
});
App.Filter = DS.model.extend({
name: DS.attr('string'),
linkPrefix: DS.attr('string')
});
//router
App.Router.map( function(){
this.resource('user', {path: '/:user_id'}, function(){});
});
//User template
<script type="text/x-handlebars" data-template-name="user">
<table class="table">
<thead>
<tr>
<th>Recording Name</th>
<th>Filters</th>
</tr>
</thead>
<tbody>
{{#each recording in recordings}}
<tr>
<td>{{name}}</td>
<td>
{{#each filter in recording}}
//pseudocode here: {{#view should combine linkPrefix +
recording_id contentBinding="recording"
(maybe??)}}{{filter.name}}{{/view}}
//also need this link to handle the click and set it to
"read" once the link has been clicked
{{/each}}
</td>
</tr>
{{/each}}
</tbody>
</table>
</div>
</script>
If it isn't obvious, in the table cell for "Filters" I want to display
names like "unfiltered" and "enhanced". Each name should link to the
appropriate version of that recording which for now will just need to open
in a new tab (I know, yuck).
So, after struggling with this for a while, I found I couldn't figure out
how to get the parent recording id and the child linkPrefix to be rendered
into a view; the big problem for me was that I couldn't get the view to
"know about" both the parent recording and the child filter. Filter.name
was a piece of cake, but I fear that this is not the "ember way." My gut
tells me there is a way to do this part without even using an each loop.
Thoughts?
