for anyone else who might come across this, i found field_error_proc.
you can over ride it and have it automatically add the errors, you can
leave the error_message_on out of your code completely. you just add
this code to an initializer.
i combined it with the second example to also stop rails from putting
those annoying divs around the fields with errors, it makes much more
sense to simply add a css class to the fields.

ActionView::Base.field_error_proc = Proc.new {|html_tag, instance|
if instance.error_message.kind_of?(Array)
%(#{html_tag}<span
class=''validation-error''>←#
{instance.error_message.join('','')}</span>)
else
%(#{html_tag}<span
class=''validation-error''>←#
{instance.error_message}</span>)
end
}

ActionView::Base.field_error_proc = Proc.new do |html_tag, instance|
if html_tag =~ /<(input|label|textarea|select)/
error_class = ''error''
nodes = Hpricot(html_tag)
nodes.each_child { |node| node[:class] = node.classes.push
(error_class).join('' '') unless !node.elem? || node[:type] ==
''hidden''
|| node.classes.include?(error_class) }
nodes.to_html
else
html_tag
end
end
