Try this
def validates_on_yours_method_name
size_letters = field.scan(/\w/).size
size_invalid = field.scan(/[A-Z]/).size
if size_invalid > 0
if (size_letters / size_invalid) < 4 and size_letters > 10
errors.add( field,
I18n.t('activerecord.errors.
messages.uppercase'))
write_attribute(field, field.downcase)
end
end
end
