Ruby on rails rails activerecord sqlserver适配器-（对象不支持检查）

我有一个应用程序正在经历从MySQL到MSSQL的转换。我们使用的是rails 3.2.22和activerecord sqlserver适配器3.2.16

在rails控制台中运行以下操作时：

irb(main):008:0* f = F5Device.first
  F5Device Load (6.1ms)  EXEC sp_executesql N'SELECT TOP (1) [dbo].[f5_devices].* FROM [dbo].[f5_devices]'
=> #<F5Device id: 5422, name: "VMIKSA69901MEM", environment: "UAT", feed_type_id: 1, scm_device_id: 121764, created_at: "2012-08-24 01:02:52", updated_at: "2017-01-19 16:08:08", gonefishing: 0>
irb(main):009:0> f.members
(Object doesn't support #inspect)
=>

---

我以前也遇到过几次

（对象不支持#inspect）

错误。结果应该仍然有效，但您只需在其处于的状态下将其打印到屏幕上即可。尝试调用

f.members.first.to_s

并查看结果。@MichaelGorman我仍然收到

NoMethodError:undefined method
