軌redirect_to的HTML格式不起作用

redirect_to的request.referer，：格式=> 「HTML」：警惕=> exception.message

當它從重定向一個js格式的控制器動作，重定向也在js中，而不是html格式。

任何線索爲什麼？謝謝！

PS：我嘗試：格式=>：HTML以及

EDIT出於完整性

重定向從這個application_controller方法

if request.referer 
     logger.debug "Rescueing Cancan" 
     redirect_to request.referer, :format => :html, :alert => exception.message 
    else 
     redirect_to root_path, :alert => exception.message, :format => :html 
    end 
    end

一個康康舞autorization之後發生這是我日誌：

嘗試使用:back在

redirect_to :back, alert: exception.message

從文檔上redirect_to：

:back - 返回發出請求的頁面。對於從多個地方觸發的表單很有用。短片爲redirect_to(request.env["HTTP_REFERER"])
