Mongoid-peperclip [回形针]内容类型欺骗:错误 [英] Mongoid-peperclip [paperclip] Content Type Spoof: Error

问题描述

我需要通过mongoid-paperclip上传一些大型CSV文件，但出现错误 Uploaded file2 my_file has an extension that does not match its contents. 在终端中，我可以看到此错误为 [paperclip] Content Type Spoof: my_file.csv (["text/csv", "text/comma-separated-values"]), content type discovered from file command: application/octet-stream. See documentation to allow this combination.好吧，我将验证设置为do_not_validate_attachment_file_type :my_file.它不能帮助相同的错误. 在application.rb中，我添加此行

I need to upload some large CSV files via mongoid-paperclip and I am getting error Uploaded file2 my_file has an extension that does not match its contents. In terminal I can see this error as [paperclip] Content Type Spoof: my_file.csv (["text/csv", "text/comma-separated-values"]), content type discovered from file command: application/octet-stream. See documentation to allow this combination. Ok, I set validation as do_not_validate_attachment_file_type :my_file It does not help same error. In application.rb I add this line

Paperclip.options[:content_type_mappings] = { jpeg: 'image/jpeg', jpg: 'image/jpeg' }

然后更改为此

Paperclip.options[:content_type_mappings] = { csv: 'text/csv'} 

它也无济于事，同样的错误 Uploaded file2 my_file has an extension that does not match its contents. 然后我将验证更改为validates_attachment_content_type:my_file，:content_type =>'text/csv' 这也没有帮助.然后我发现有人建议这样做

It also does not help, same error Uploaded file2 my_file has an extension that does not match its contents. Then I changed validation to validates_attachment_content_type :my_file, :content_type => 'text/csv' It also did not help. Then I found some one suggesting to do this

`require 'paperclip/media_type_spoof_detector'         
module Paperclip         
 class MediaTypeSpoofDetector        
    def spoofed?         
      false       
    end       
  end        
end 

但是我应该在哪里做呢?在哪个文件中?在哪个目录? (我正在使用Rails 4.0) 如果有人知道如何解决此错误，请告诉我！谢谢！ `

But where I should do this? in which file? in which directory? (I am using rails 4.0) If any one knows how to fix this error, please let me know! Thank you! `
