jquery - Rails3 Paperclip JCrop 进入循环

Question

我有这个配置的典型设置，没什么特别的，就像本教程中的一样:http://shareyourtechskills.blogspot.com/2011/01/jcrop-with-paper-clip-plugin.html

上传头像 - 工作正常，但当我裁剪它时，进程卡在循环中，并在控制台中出现以下错误:

这个字符串大约有 500 个，然后我得到这个:

也是大约 500，然后我在浏览器中收到此错误:

SystemStackError in UsersController#update
stack level too deep

我很感兴趣，如果我只修剪一张，为什么会有这么多图片？谢谢

Answer 1

大多数文章已过时且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，如评论中所述 http://railscasts.com/episodes/182-cropping-images?view=comments#comment_160006福纳说，那

    avatar.reprocess!

必须不是从模型而是从这样的 Controller 调用:

    @user.avatar.reprocess!

当然，您需要验证它是否存在裁剪变量，例如 crop_x 和其他附言感谢 Fona 的评论。
