堆栈级别太深：Spree 管理员 - 产品图片

Question

我在 spree 2.3.0 的生产环境中遇到 Stack Level Too Deep 错误。

当我尝试转到管理面板中的产品图片索引页面时发生。此错误不会发生在开发中，只会发生在 Ninefold 的生产中。当我在生产模式下本地运行应用程序时，不会发生错误。我似乎可以追踪是什么原因造成的。我没有更改 Spree 中与产品图片相关的任何默认核心功能。图像在前端渲染良好。

我正在使用回形针和 aws。有一次生产没有错误。但是，我检查了我所有的提交，但无法查明导致此问题的更改。我已经添加了其他 gems，但是 none 的 gems 与回形针 gems 或其依赖项发生冲突，这是我对可能导致此问题的猜测。

这里是生产日志错误。

所以在检查了我安装的所有 gem 之后，我终于找到了问题所在。

Spree::Admin::ImagesController 装饰器中的 alias_method 导致了 Stack Level Too Deep 错误。
