Question

我试图将我的Spree购物车与AWS S3连接以上传产品图片，但是我一直收到错误消息：

.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：

宝石文件

ruby '2.4.0'
gem 'rails', '~> 5.2.0'
gem 'spree', '~> 3.6.0'
gem 'spree_auth_devise', '~> 3.3'

gem 'spree_static_content', github: 'spree-contrib/spree_static_content'
gem 'aws-sdk', '~> 2.3'

config / initializers / 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

有人遇到这个错误并有解决方案吗？

Answer 1

spree.rb中的注释行attachment_config

在config/storage.yml中声明Active Storage服务。对于您的应用程序使用的每项服务，请提供名称和必要的配置。

amazon:
  service: S3
  access_key_id: ""
  secret_access_key: ""
  bucket: ""
  region: "" # e.g. 'us-east-1'

要在生产中使用Amazon S3服务，请将以下内容添加到config/environments/production.rb：

config.active_storage.service = :amazon

将aws-sdk-s3宝石添加到您的Gemfile中：

gem "aws-sdk-s3", require: false

Answer 2

对于以后遇到此问题的任何人，这就是我已解决的方法。

如果您将Spree :: User类作为初始化程序进行编辑，则问题在于'active_storage / reflection'中的初始化程序未运行。因此，请在您的class_eval块的开头添加以下行：

include ActiveStorage::Reflection::ActiveRecordExtensions

ActiveRecord::Reflection.singleton_class.prepend(ActiveStorage::Reflection::ReflectionExtension)

include ActiveStorage::Attached::Model

然后，应加载ActiveStorage，您将能够找到方法has_one_attached :image

Answer 3

该配置也不适用于我。实际上，步骤非常简单。在storage.yml中声明Amazon配置，添加aws gem，就可以开始了。 ActiveStorage文档包含了所有内容。 http://edgeguides.rubyonrails.org/active_storage_overview.html#setup

未定义的方法“ has_one_attached”-Spree，AWS S3，产品图片，Rails
