回形针 - 如何上传PDF？

Question

我有一个模型将图像和pdf上传到Amazon S3 - 图像工作,pdf没有.

这就是我的模型:

validates_attachment_content_type :photo, :content_type => ['image/jpeg', 'image/png', 'image/gif']
has_attached_file :pdf,
    :storage => :s3,
    :s3_credentials => "#{::Rails.root.to_s}/config/s3.yml",
    :path => "/userpdfs/:id/:basename.:extension"
has_attached_file :photo,
    :styles => {:medium => "200x300>", :thumb => "100x150>" },
    :storage => :s3,
    :s3_credentials => "#{::Rails.root.to_s}/config/s3.yml",
    :path => "/userphotos/:style/:id/:basename.:extension"

亚马逊正在展示userphotos但没有userpdfs.两种类型在我的数据库中都有四个字段:

pdf_name
pdf_type # could also be a word doc
pdf_size
pdf_updated_at

1. 为什么不上传简历(图片可以!)
2. 如何验证:pdf字段只允许.pdf,.doc,.docx,.txt？

编辑

将任何图像上传到:pdf字段都可以!关于pdfs本身的一些东西似乎搞乱了系统.我的服务器说它已将文件保存到S3但它们没有出现在目录中.

PDF现在只有在标题中没有空格时才起作用.有了空格,我收到以下错误:Errno::EPIPE: Broken Pipe.

试试这个

>> Attachment.last.file_path
=> "https://s3.amazonaws.com/content.dynamixccw.com/attachments/4/Financial goal Report.pdf"
>> url = _
=> "https://s3.amazonaws.com/content.dynamixccw.com/attachments/4/Financial goal Report.pdf"
>> url.gsub(' ', '%20')
=> "https://s3.amazonaws.com/content.dynamixccw.com/attachments/4/Financial%20goal%20Report.pdf"

要验证,请将其丢弃

validates_attachment_content_type :pdf, :content_type => ['application/pdf', 'application/msword', 'text/plain'], :if => :pdf_attached?

def pdf_attached?
  self.pdf.file?
end
