未定义的方法 `has_one_attached' - Spree、AWS S3、产品图片、Rails

Question

我正在尝试将我的 Spree 购物车与 AWS S3 连接以上传产品图片，但我不断收到错误消息：

.rbenv/versions/2.4.0/lib/ruby/gems/2.4.0/gems/activerecord-5.2.0/lib/active_record/dynamic_matchers.rb:22:in `m
ethod_missing': undefined method `has_one_attached'

这是我的设置：

文件

ruby '2.4.0'
gem 'rails', '~> 5.2.0'
gem 'spree', '~> 3.6.0'
gem 'spree_auth_devise', '~> 3.3'
gem 'spree_gateway', '~> 3.3'
gem 'globalize', github: 'globalize/globalize'
gem 'spree_i18n', github: 'spree-contrib/spree_i18n'
gem 'spree_globalize', github: 'spree-contrib/spree_globalize', branch: 'master'
gem 'spree_static_content', github: 'spree-contrib/spree_static_content'
gem 'aws-sdk', '~> 2.3'

配置/初始化程序/spree.rb

attachment_config = {

    s3_credentials: {
      access_key_id:     ENV['AWS_ACCESS_KEY_ID'],
      secret_access_key: ENV['AWS_SECRET_ACCESS_KEY'],
      bucket:            ENV['S3_BUCKET_NAME']
    },

    storage:        :s3,
    s3_region:      ENV['S3_REGION'],
    s3_headers:     { "Cache-Control" => "max-age=31557600" },
    s3_protocol:    "https",
    bucket:         ENV['S3_BUCKET_NAME'],
    url:            ":s3_domain_url",

    styles: {
        mini:     "48x48>",
        small:    "100x100>",
        product:  "240x240>",
        large:    "600x600>"
    },

    path:           "/:class/:id/:style/:basename.:extension",
    default_url:    "/:class/:id/:style/:basename.:extension",
    default_style:  "product"
  }

  attachment_config.each do |key, value|
    Spree::Image.attachment_definitions[:attachment][key.to_sym] = value
  end

有没有人遇到过这个错误并有解决方案？

该配置对我来说也不起作用。实际上步骤非常简单。在 storage.yml 中声明 amazon 配置，添加 aws gem，然后就可以开始了。ActiveStorage 文档包含一切。http://edgeguides.rubyonrails.org/active_storage_overview.html#setup
