Question

我无法附加XLS文件，但DOC有效：

附件文件内容类型无效
附件文件无效

这是日志：

Parameters: ... "files"=>[#<ActionDispatch::Http::UploadedFile:0x0000000daf7730 @tempfile=#<Tempfile:C:/Users/Chloe/AppData/Local/Temp/RackMultipart20170511-47156-ym774u.xls>, @original_filename="Chocolate_Store1.xls", @content_type="application/vnd.ms-excel", @headers="Content-Disposition: form-data; name=\"deal[files][]\"; filename=\"Chocolate_Store1.xls\"\r\nContent-Type: application/vnd.ms-excel\r\n">],
...
Command :: file -b --mime "C:/Users/Chloe/AppData/Local/Temp/1f1fb4d71efc0bd245abd7b5b9aa661220170511-47156-1rqzd0q.xls"
   (1.0ms)  ROLLBACK
  Rendering deals/edit.html.erb within layouts/application

当我测试类型时：

>file -b --mime "C:/Users/Chloe/AppData/Local/Temp/1f1fb4d71efc0bd245abd7b5b9aa661220170511-47156-1rqzd0q.xls"
application/vnd.ms-office; charset=binary

我的接受列表中有这种类型：

class Attachment < ApplicationRecord
  has_attached_file :file
  validates_attachment_content_type :file, content_type: [
    "application/pdf", "application/msword", 
    "application/vnd.openxmlformats-officedocument.wordprocessingml.document", 
    "application/vnd.oasis.opendocument.text",
    "application/vnd.ms-excel",
    "application/vnd.ms-office",
    "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet",
    "application/vnd.oasis.opendocument.spreadsheet"
   ]

end

Rails 5.0.2，Paperclip 5.1.0，文件5.04（DevKit）

我注意到DevKit file与Cygwin file不同。不确定是否相关：

>file -b --mime "C:/Users/Chloe/AppData/Local/Temp/1f1fb4d71efc0bd245abd7b5b9aa661220170515-54920-1e2bk5s.xls"
application/vnd.ms-office; charset=binary

$ file -b --mime "C:/Users/Chloe/AppData/Local/Temp/1f1fb4d71efc0bd245abd7b5b9aa661220170515-54920-1e2bk5s.xls"
application/vnd.ms-excel; charset=binary

Answer 1

我切换到使用

validates_attachment_file_name :file, matches: [/\.pdf$/, /\.docx?$/, /\.xlsx?$/, /\.odt$/, /\.ods$/]

Answer 2

...content_type: [...'application/x-ole-storage'...]

为我工作
