RAILS 6从失败的单元结果获取错误消息
是否有可能收到作为失败单元结果传递的错误消息？据我所见，为提供了方法成功> ，但是否也可以从失败中获取消息？
response[0]
=> Failure("12345 - Product code is not valid")
像：
response[0].message
=> "12345 - Product code is not valid"
Is it possible to get error message which was passed as a Failure monad result? as far as I can see the value! method is provided for Success but is it possible to get message from Failure as well?
response[0]
=> Failure("12345 - Product code is not valid")
to be something like:
response[0].message
=> "12345 - Product code is not valid"
