I am getting an error that I cannot figure out:

ActionView::MissingTemplate (Missing template cluster/delete_stuff.erb in view path app/views)
<...snip trace...>
Rendering rescues/layout (internal_server_error)

I am "enhancing" others code and am following the convention they set up, where they have have code like:

<%= render :partial => "other_stuff" %>

And a file named _other_stuff.html.erb and it all works, but when I copy these little snippets, I get the above error. Any ideas? Something is going on here that I need to figure out.
