Question

我有问题我将对象id传递给另一个控制器到另一个控制器之间我使用devise gem执行sign_in操作，当sign_in完成后，下一页显示错误＆＃34; Active record :: RecordNotFound BookingController #index＆＃34;并且＆＃34;找不到没有身份证的房间＆＃34; ##我执行步骤中的操作 1：当我浏览＆＃34; guest_search＆＃34;页面我使用＆＃34; Ransack gem＆＃34;进行了搜索操作。当搜索完成后，我使用params [：id]获取特定id并发送给另一个控制器l.e roomcontroller.rb。
