No underscore/dash escaping in Mongoid

mongoid.rb

# Instead of the standard composition, convert everything
# non-alpha and non-digit to dash and squeeze
class String
  def identify
    if Mongoid.parameterize_keys
      gsub(/[^a-z0-9]+/, ' ').strip.gsub(' ', '-')
    else
      self
    end
  end
end

only this version (https://gist.github.com/749649/87ae99a47430846d2854aae63192d4704c423b71) working properly for turkish charset ( Öö Çç Üü Şş Iı İi Ğğ)
