Rails - Sep 2006 - Work around for problems with error_message_on

Hey all

I was encountering problems with error_message_on in the fact that it 
caused an exception when no object by that name had any errors (or did 
not exsist) so i created this work around...

  def display_error(obj, method, prepend_text = "", append_text =
"",
css_class = "form_error")
    object = instance_variable_get("@#{obj}")
    if object && !object.errors.empty?
      errors = object.errors.on(method)
      if errors
        content_tag("div", "#{prepend_text}#{errors.is_a?(Array)
?
errors.first : errors}#{append_text}", :class => css_class)
      end
    else
      return nil
    end
  end

It just checks to see if there are any errors before trying to present 
them

Hope this might one day help somone else!

Tim
