当文件不是有效的附件内容类型时，Paperclip :: NotIdentifiedByImageMagickError
当我尝试上传不在["image/jpg", "image/jpeg", "image/gif", "image/png", "image/pjpeg", "image/x-png"]的文件时，我系统地出错了["image/jpg", "image/jpeg", "image/gif", "image/png", "image/pjpeg", "image/x-png"]
当我尝试上传像’wav’这样的文件时，我收到了这条消息
* Photo /var/folders/nT/nTr21TWfFRO7r3cyG-h-7++++TM/-Tmp-/Clip audio 01,39154,0.wav is not recognized by the 'identify' command. * Photo /var/folders/nT/nTr21TWfFRO7r3cyG-h-7++++TM/-Tmp-/Clip audio 01,39154,0.wav is not recognized by the 'identify' command. * Photo content type Accepted files include: jpg, gif, png
因此，它检测到该文件不是图像并显示我的消息"Accepted files include: jpg, gif, png"但是在我的照片未被’identify’命令识别之前我已经包含了这个额外的消息…上传工作正常对于图片
我的代码是：
控制器：
def upload @picture= Picture.new(params[:picture]) if !@picture.valid? render :form end end
查看表格：
nil, :message => nil %> "uploadPic", :url => { :action => 'upload_data'}, :html => {:name => 'uploadForm', :multipart => true } do |form| %>
图片型号：
class Picture { :medium => "300x300>", :thumb => "100x100>" } validates_attachment_size :photo, :less_than => 2.megabytes , :message => "must be less than 2 megabytes" validates_attachment_content_type :photo, :content_type => ["image/jpg", "image/jpeg", "image/gif", "image/png", "image/pjpeg", "image/x-png"], :message => "Accepted files include: jpg, gif, png" end
解决了它：whiny => false
has_attached_file：photo，：whiny => false，：styles => {：medium =>“300×300>”，：thumb =>“100×100>”}
：whiny => false不足以解决最新版回形针（2.3.6）的问题。 我最终在rails初始化器中执行此操作：
module Paperclip class Attachment alias original_assign assign def assign(*args) original_assign(*args) rescue NotIdentifiedByImageMagickError => e end end end
似乎可以吞下该exception，因为至少如果使用：whiny => true，则无论如何都会添加validation错误。
