Dynamically render partial templates using mustache

Question

Is there a way to dynamically inject partial templates (and have it work the same way in both Ruby & Javascript)? Basically, I'm trying to render different types of objects in a list.

The best I can come up with is this:

<div class="items">
{{#items}}
<div class="item">
  {{#is_message}}
  {{> message}}
  {{/is_message}}

  {{#is_picture}}
  {{> picture}}
  {{/is_picture}}
</div>
{{/items}}
</div>

I'm not super-psyched about this approach. Is there a better way?

Also note that the different types of models for the views can have non-similar fields. I suppose I could always go to the lowest common denominator and have the data hash contain the html, however I would rather use the mustache templates.
