Ruby on rails 在ruby中“未定义的方法”是什么意思

我在生产中遇到了工作延误的麻烦。我得到了未定义的方法SOMEMETHOD for error，我想了解的是for的含义。它既不是一个Fixnum，也不是一个类。我想知道是什么

我的追踪：

我添加了我的跟踪，因为它再次发生。上次，我发现了问题所在。Delayed_jobs没有显示全部内容，事实证明，这是一个Shopify ActiveResource实例。这一次，这是一个不同的方法，我真的不知道是什么。不确定这是哪个类。

当您报告错误时，显示生成错误的源代码行几乎总是有帮助的。堆栈跟踪对于找出哪里出了问题非常有帮助。否则，如果你不具体说明，这是一个猜测游戏。同意。我会确保包括下次！错误消息看起来真的像是未定义的SOMEMETHOD吗？不在延迟作业中我同意@muistooshort-我想你的错误消息有一个类名，但它被什么东西吞没了。你从网页复制了跟踪吗？
