How to render an Ember template to a string? [duplicate] - templates

Question

I just want to run the template string against an object and examine the result
I have a string that is a template. I've "compiled" it. Now I want to run it against an object and examine the result.
But this doesn't work:
var template = '<div>{{#each items}}<div>{{item}}</div>{{/each}}</div>';
var compiled = Ember.Handlebars.compile(template);
var result = compiled({ items: [1, 2, 3] }); // ERRORS
What I want to get is the DOM result of running my compiled string against an object. In other words, a set of DOM elements that looks something like this:
<div>
<div>1</div>
<div>2</div>
<div>3</div>
</div>
It appears that Ember.Handlebars.compile is very tightly coupled to other parts of an Ember application, to the point it expects a lot of things to be populated in the context I'm passing ot the compiled function. I have yet to figure out what all of these things are, or if there is a better way to create a context to pass to the compiled function.
Other things:
I don't want to use plain "non-Ember" Handlebars.
I'd like to avoid creating an Ember Application if I can.
I don't really want to answer questions about "why" I want to do this. This is what I want to do. :P

Why do you want to do this? ;)
Honestly the easiest way to do this will be to create a view. Ember hooks up a bunch of fancy rendering stuff when it calls compile due to the data binding etc, so it's difficult to create it straight from the compile function (it passes in a slew of additional stuff, like buffers etc...)
var view = Ember.View.extend({
template:Ember.Handlebars.compile('hello <div>{{#each item in view.items}}<div>{{item}}</div>{{/each}}</div>')
});
var foo = view.create({ items: [1, 2, 3] });
foo.appendTo('#blah');
Example

// you must wait for all bindings to sync before you can check the contents of #blah:
var empty = $('#blah').html(); // this will be empty
Ember.run.next(function(){
var notEmpty = $('#blah').html(); // this will have the proper result in it
});
or you can hook up to the didInsertElement callback
var foo = view.create(blah);
foo.didInsertElement = function(){
console.log(foo.$().html());
}
foo.appendTo('#blah');

The bindings are still in tact when you create a Ember handlebars template, so you can modify the object passed in and it will update the template.
