Jquery Rails3回形针JCrop进入了环路

我有这种配置的典型设置，没有什么特别之处，类似于本教程：

上传头像-工作正常，但当我裁剪它时，进程陷入循环，控制台中出现以下错误：

这个字符串大约有500个，然后我得到：

大约500，然后我在浏览器中得到这个错误：

SystemStackError in UsersController#update
stack level too deep

我很感兴趣，为什么有这么多的图片，如果我只修剪一个？

大多数文章已经过时，与当前版本的回形针和rails不兼容，因此此配置需要重新组织，如本文所述 丰纳说,

    avatar.reprocess!

必须不是从模型调用，而是从如下控制器调用：

    @user.avatar.reprocess!

当然，您需要验证它是否存在裁剪变量，如crop_x和其他 谢谢你的评论
