Forum: RForum Set locale

Is there any beter way to write this?



 before_filter :set_locale

  def set_locale
    if(params[:locale] and params[:locale].match /^(da|en|de)$/)
      I18n.locale = params[:locale]
    elsif session[:locale] == nil
      xxx = request.env['HTTP_ACCEPT_LANGUAGE'].scan(/^[a-z]{2}/).first
      if xxx.match /^(da|en|de)$/
        I18n.locale = xxx
      else
        I18n.locale = 'en'
      end
    else
      I18n.locale = session[:locale] || 'en'
    end
    session[:locale] = I18n.locale
  end
