Ruby on rails 在特定操作后重定向

我在mailboxer gem上遇到了一些问题。回复和垃圾箱具体来说，邮件被回复，当选择删除时也被发送到垃圾箱，但我无法成功地将其重定向到收件箱。我总是收到错误，无法找到id为的用户以下是我的垃圾箱部件控制器代码-

  def trash

      conversation = Conversation.find(params[:id])

      beta = current_userA || current_userB

         case beta

          when current_userA

            conversation.move_to_trash(current_userA)

            # redirect_to :conversations

          when current_userB

           conversation.move_to_trash(current_userB)

           # redirect_to :conversations

         end



    respond_to do |format|      
       format.html { redirect_to conversation_path, notice: 'Conversation successfully trashed.' }        
    end

end

日志 更新日志 将重定向_更改为对话后，将重定向_更改为对话

请告诉我我做错了什么，我已经做了一天，我还没有找到任何解决办法。不用说，userA和userB都是不同的Desive用户。欢迎对此提出任何建议。

尝试在重定向中使用路径，您可以从rake_routes获得该路径。也许下面给出的例子对你有用

respond_to do |format|
    format.html { redirect_to inbox_path, notice: 'Conversation successfully trashed.' }    
end

为什么重定向被注释掉了？具体的异常消息是什么？请复制并粘贴它？你在哪行收到错误，我不使用任何用户。在这里查找…？@Michal我明天肯定会发布错误，因为我目前无法访问我的机器。在那之前，请你把你的答案贴在我应该把用户写在哪里。查找代码我不能不看代码就给你答案。上面的代码显然不完整。@MichalSzyndel这是垃圾箱的控制器代码，请告诉我您还需要什么。@MichalSzyndel-发布操作日志

respond_to do |format|
    format.html { redirect_to inbox_path, notice: 'Conversation successfully trashed.' }    
end
