ruby-on-rails - Paperclip::NotIdentifiedByImageMagickError 当文件不是有效的附件内容类型时

Question

当我尝试上传不在 ["image/jpg", "image/jpeg", "image/gif", "image/png", "图片/pjpeg", "图片/x-png"]

当我尝试上传类似“wav”的文件时，我收到此消息

* Photo/var/folders/nT/nTr21TWfFRO7r3cyG-h-7++++TM/-Tmp-/Clip audio 01,39154,0.wav 无法被“identify”命令识别。
* Photo/var/folders/nT/nTr21TWfFRO7r3cyG-h-7++++TM/-Tmp-/Clip audio 01,39154,0.wav 无法被“identify”命令识别。
* 图片内容类型接受的文件包括:jpg、gif、png

因此它检测到该文件不是图像并显示我的消息 “接受的文件包括:jpg、gif、png” 但是我在我的照片无法识别之前包含了这条额外的消息“识别”命令...上传图片效果很好

我的代码是:

Controller :

def upload  
  @picture= Picture.new(params[:picture])  
    if !@picture.valid?  
        render  :form  
    end  
end  

查看表单:

<%= error_messages_for :picture, :header_message => nil, :message => nil %>  
<% form_for :picture, @picture, :name => "uploadPic", :url => { :action => 'upload_data'}, :html => {:name => 'uploadForm', :multipart => true } do |form| %>  
    <%= form.file_field :photo %>  
    <%= submit_tag 'Save'%>  
<% end %>

图片模型:

 class Picture < ActiveRecord::Base    
    require 'paperclip'  
    has_attached_file :photo, :styles => { :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

用 :whiny => false 解决了它
has_attached_file :photo, :whiny => false, :styles => { :medium => "300x300>", :thumb => "100x100>"}
