Question

使用Rails 5.2，红宝石2.4宝石载波

gem 'carrierwave', '~> 1.0'

当我使用扩展名mdl和内容类型上传时：application / octet-stream 返回文件保存以下错误

    ["Job data file You are not allowed to upload \"mdl\" files, 
allowed types: jpg, jpeg, gif, png, application/octet-stream"]

但是我包含了内容类型：application / octet-stream，如错误所示。我的上传器文件为：

class JobDataFileUploader < CarrierWave::Uploader::Base
  # Include RMagick or MiniMagick support:
  # include CarrierWave::RMagick
  # include CarrierWave::MiniMagick

  # Choose what kind of storage to use for this uploader:
  storage :file
  # storage :fog

  # Override the directory where uploaded files will be stored.
  # This is a sensible default for uploaders that are meant to be mounted:
  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end

  # Provide a default URL as a default if there hasn't been a file uploaded:
  # def default_url(*args)
  #   # For Rails 3.1+ asset pipeline compatibility:
  #   # ActionController::Base.helpers.asset_path("fallback/" + [version_name, "default.png"].compact.join('_'))
  #
  #   "/images/fallback/" + [version_name, "default.png"].compact.join('_')
  # end

  # Process files as they are uploaded:
  # process scale: [200, 300]
  #
  # def scale(width, height)
  #   # do something
  # end

  # Create different versions of your uploaded files:
  # version :thumb do
  #   process resize_to_fit: [50, 50]
  # end

  # Add a white list of extensions which are allowed to be uploaded.
  # For images you might use something like this:
  def extension_whitelist
    %w(jpg jpeg gif png application/octet-stream)
  end

  # Override the filename of the uploaded files:
  # Avoid using model.id or version_name here, see uploader/store.rb for details.
  # def filename
  #   "something.jpg" if original_filename
  # end
end

Answer 1

更新了的上载文件

  def extension_whitelist
    %w(mdl)
  end

我将采用与回形针相同的内容类型来进行验证，例如“ application / octet-stream”。

Gem Carrierwave不允许上传应用程序/八位字节流文件
