If you ever want to render a partial but don't want an error thrown you can either check for the existence of the file first
<%= render :partial => params[:controller]+"/sidebar" if File.exists?(RAILS_ROOT+"/app/views/"+params[:controller]+"/_sidebar.html.erb") %>
or you can catch the error that Rails throws
<%= render :partial => params[:controller]+"/sidebar" rescue nil %>
