我真的可以通过我使用Devise for users和Paperclip为图片上传构建的应用程序，将配置文件图像正确上传到S3时使用一些帮助。
我的其他模型都通过Hercl到3的Paperclip工作得很好，我唯一无法工作的模型是Devise的用户模型。我已经阅读了100篇关于为设计设置配置的允许参数的不同文章，似乎没有变量可行。我已经阅读了有关此问题的所有Stack Overflow Q＆amp; A，似乎没有与我的相关。
我在用户模型中添加了其他属性（配置文件名称，dob等），所有这些属性都正常工作。只有图像不起作用。
我已经在完整的日志文件下面显示了错误消息 - “未经许可的参数：宝丽来。”
Paperclip'image'文件名称为'Polaroid'。
有什么想法？谢谢！
