Showing validation errors next to its field

Question

Is there any way to show errors not on top of form page, but next to field, that fired an error?

Answer 1

initializers/my_custom_error_messages.rb

ActionView::Base.field_error_proc = Proc.new do |html_tag, instance|
  errors = Array(instance.error_message).join(',')
  %(#{html_tag}<span class="validation-error">&nbsp;#{errors}</span>).html_safe
end

update:

without label

ActionView::Base.field_error_proc = Proc.new do |html_tag, instance|
  errors = Array(instance.error_message).join(',')

  if html_tag =~ /^<label/
    html_tag
  else
    %(#{html_tag}<span class="validation-error">&nbsp;#{errors}</span>).html_safe
  end

end
