the part/update method isn't typically used for rendering arbitrary code. http://cookbook.hobocentral.net/manual/ajax#the_part_context
to do what you're after, you'd probably want something like this: def update_result @result = 'some returned text' end <div part="update_result"><%= @result %></div> on the first pass, @result is blank (or contains some other info). when the form is submitted, the variable is set and the part mechanism re-renders the part context with the new info. if all you're after is updating like this without dryml or an active record model(s) in the part, you can get same effect with regular rails link_to_remote like you were describing.
