挣扎于回形针内容类型，需要上传xls / xlsx文件。

Command :: file -b --mime '/var/folders/zy/khy_wsfn7jbd40bsdps7qwqc0000gt/T/5a76e813d6a0a40548b91acc11557bd220160328-13642-1meqjap.xlsx'
   (0.2ms)  BEGIN
Command :: file -b --mime '/var/folders/zy/khy_wsfn7jbd40bsdps7qwqc0000gt/T/5a76e813d6a0a40548b91acc11557bd220160328-13642-114d8t6.xlsx'
   (0.3ms)  ROLLBACK
{:sheet_content_type=>[" Only EXCEL files are allowed."], :sheet=>[" Only EXCEL files are allowed."]}

修正了它

has_attached_file :sheet,
                :path => ":rails_root/public/system/:attachment/:id/:filename"

validates_attachment :sheet, presence: true,
                   content_type: { content_type: [
                     "application/vnd.ms-excel",
                     "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"
                   ]
                   },
                   message: ' Only EXCEL files are allowed.'
