Or you could just add
ActionView::Base.field_error_proc = Proc.new do |html_tag, instance| “<span class="error">#{html_tag}” end
to your config/environment.rb. I agree that using a div [block] where a span [inline] would work as well seems overkill but I didn’t create Rails. And granting how awesome all the other stuff is, I think I’ll let this one slide.
