Hi,

just override the default helper.

here’s the source (ie put this in your helper, and then change it to  
fit)

def error\_messages\_for(\*params)  
options = params.extract\_options!.symbolize\_keys  
if object = options.delete(:object)  
objects = [object].flatten  
else  
objects = params.collect {|object\_name|  
instance\_variable\_get(“@#{object\_name}”) }.compact  
end  
count = objects.inject(0) {|sum, object| sum +  
object.errors.count }  
unless count.zero?  
html = {}  
[:id, :class].each do |key|  
if options.include?(key)  
value = options[key]  
html[key] = value unless value.blank?  
else  
html[key] = ‘errorExplanation’  
end  
end  
options[:object\_name] ||= params.first  
options[:header\_message] = “#{pluralize(count, ‘error’)}  
prohibited this #{options[:object\_name].to\_s.gsub(‘\_’, ’ ')} from  
being saved” unless options.include?(:header\_message)  
options[:message] ||= ‘There were problems with the following  
fields:’ unless options.include?(:message)  
error\_messages = objects.map {|object|  
object.errors.full\_messages.map {|msg| content\_tag(:li, msg) } }

```
 contents = ''
 contents << content_tag(options[:header_tag] || :h2,

```

options[:header\_message]) unless options[:header\_message].blank?  
contents \<\< content\_tag(:p, options[:message]) unless  
options[:message].blank?  
contents \<\< content\_tag(:ul, error\_messages)

```
 content_tag(:div, contents, html)

```

else  
‘’  
end  
end
