Paperclip 在某些图像上失败，但继续将图像分配给模型
我的应用程序与 FB 集成。当用户没有图像时，FB 返回：

虽然这看起来像普通的 gif，但它破坏了回形针：

即使出现错误，回形针仍然将图像保存到模型中。
问题：
为什么会损坏？
我如何告诉回形针，如果出现处理错误，则中止图像，而不是整个过程，因为我还保存名称等，但至少阻止图像保存最终导致 404ing 的死文件。< /p>
谢谢
my app integrates with FB. When the user has no image, FB returns:

While that looks like a normal gif, it breaks paperclip:

[paperclip] An error was received while processing: #<Paperclip::PaperclipError: There was an error processing the thumbnail for stream20110517-560-1y0qj3p-0>
Even with the error, paperclip still saves the image to the model.
Questions:
Why is it breaking?
How can I tell paperclip that if there is a processing error, abort the image, not the entire process as I'm also saving names etc, but at least stop the image from saving a dead file that ends up 404ing.
Thanks

看起来它实际上是一个损坏的图像。下载它并运行
identify -format %wx%h yDnr5YfbJCH.gif会抛出错误：因此您可以将此归咎于 Facebook。
Rob on Rails 有一个关于如何验证上传的是有效图片。这应该能让您的最终用户顺利工作。
It looks like it is actually a corrupt image. Downloading it and running
identify -format %wx%h yDnr5YfbJCH.gifthrows the error:So you can blame Facebook for that one.
Rob on Rails has a good example on how to validate that an upload is a valid image. That should make things work nicely for your end users.
