ruby-on-rails - 缺少必需的选项 :name

Question

我正在尝试设置 AWS 和carrierwave 从我的网站上传图片。但是，当我尝试上传/更新帖子时，我不断收到错误消息“缺少必需的选项:名称”。我按照教程设置了我的 S3 帐户并设置了carrierwave.rb。如果您有任何想法，请告诉我!

载波

CarrierWave.configure do |config|
 config.storage    = :aws
 config.aws_bucket = ENV['S3_BUCKET_NAME']
 config.aws_acl    = 'public-read'
 config.aws_authenticated_url_expiration = 60 * 60 * 24 * 7
 config.aws_attributes = {
   expires: 1.week.from_now.httpdate,
   cache_control: 'max-age=604800'
 }

 config.aws_credentials = {
   access_key_id:     ENV['AWS_ACCESS_KEY_ID'],
   secret_access_key: ENV['AWS_SECRET_ACCESS_KEY'],
   region:            ENV['AWS_REGION']
 }
end

.env 示例

S3_BUCKET_NAME=*****
AWS_ACCESS_KEY_ID=*****
AWS_SECRET_ACCESS_KEY=*****
AWS_REGION=*****

投资组合_上传者.rb

class PortfolioUploader < CarrierWave::Uploader::Base

  storage :aws

  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end

  def extension_white_list
    %w(jpg jpeg gif png)
  end
end

Answer 1

我也遇到了这个问题。错误消息具有欺骗性。我发现它实际上是config.aws_bucket = ENV['S3_BUCKET_NAME']导致问题的行。如 config.aws_bucket是 nil (比如当ENV['S3_BUCKET_NAME']未设置时，你会在控制台中得到欺骗性的missing required option :name。
