Question

此操作不起作用：

redirect_to request.referer，：format =＆gt; “html”，：alert =＆gt; exception.message

当它以js格式从控制器动作重定向时，重定向也是js，而不是html格式。

有什么线索的原因？ THX！

PS：我试过了：format =＆gt; ：html也是

编辑完整性

通过此application_controller方法

进行cancan自动化后，重定向发生

   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

这是我的日志：

Answer 1

尝试使用

中的:back

redirect_to :back, alert: exception.message

来自redirect_to上的文档：

:back - 返回发出请求的页面。适用于从多个位置触发的表单。 redirect_to(request.env["HTTP_REFERER"])
的简写

rails redirect_to html格式不起作用
