Steve,
You reference a partial in your master layout file, application.rhtml
which resides in views/layouts. You will need to include the path to
the partial though.
For example, if you have a login form in apps/views/sessions/
_form.rhtml
then you could reference that in your application.rhtml file as:
<%= render :partial => 'sessions/_form.html' %>
Cheers,
Nicholas
