hi julian i tried with ur code but the code stuck in second line
itself.i pasted the code in helper.rb as you said but im getting error
when executing.

the error is:

“{ undefined method `extract_options!’ for [“valuecheck”]:Array
}”

here “valuecheck” => is my model’s name.

im new to ror julian i dont know how to proceed with this.please help
me if u know what’s wrong.

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
