Programmatically render spacer_template
===

I have a rails spacer template that's used in between renderings of a collection. For example, it might be as simple as

    <hr />

If I render a collection of users for example then after each user it will render `<hr />`

This works fine but I was wondering if there's a way to render the spacer template by itself from within my controller. Something like `render_to_string` but specifically for just the spacer template.

I need this because I am doing an ajax request to add a user comment. Right now I can successfully render the comment with `render_to_string` but since it's not a collection the spacer template is not showing up.
