Question

When saving a form and a field fails validation, I don’t want the label to be modified at all.
I don’t mind wrapping the input with a div and a class of “field_with_errors”, but how can I stop it from wrapping the label as well?

I wasn’t able to find anything in the ActionView::Base documentation about the field_error_proc method, but here is the solution I came up with. Hopefully this will help others!

 ActionView::Base.field_error_proc = Proc.new do |html_tag, instance| 
  unless html_tag =~ /^<label/
    "<div class=\"field_with_errors\">#{html_tag}</div>".html_safe
  else
    html_tag.html_safe
  end
end
