CarrierWave扩展白名单错误消息

根据@mizurnix建议的解决方案回答。这对我很有用。

超越了 check_extension_whitelist! avatar uploader(app/uploaders/avatar_uploader.rb)中的方法,即在avatar_uploader.rb中添加以下代码。

private

  def check_extension_whitelist! new_file
    extension = new_file.extension.to_s
    if extension_whitelist && !whitelisted_extension?(extension)
      raise CarrierWave::IntegrityError, I18n.translate(:"errors.messages.extension_whitelist_error", extension: extension, allowed_types: Array(extension_whitelist).join(", "))
    end
  end

  def whitelisted_extension? extension
    downcase_extension = extension.downcase
    Array(extension_whitelist).any? { |item| downcase_extension =~ /\A#{item}\z/i }
  end
