我被困住了，即使我找到了一些关于这个问题的主题，我也没有找到任何解决方案。

如果我的“Packer”注册到我们的时事通讯，我正在尝试添加对 Mailchimp 的订阅（“Packer”是一种“用户”-“用户”只有设计参数，“包装器”有其余参数）

该错误是一个未初始化的常量，似乎是因为 rails 无法识别我的服务。

这是我的#app/models/packer.rb

after_create :subscribe_to_newsletter
after_update :subscribe_to_newsletter
private
def subscribe_to_newsletter
  SubscribeToNewsletterService.new.call(self.user) if self.newsletter
end

和我的 #app/services/subscribe_to_newsletter_service.rb

require "gibbon"
class SubscribeToNewsletterService
  def initialize
    @gibbon = Gibbon::Request.new(api_key: ENV['MAILCHIMP_API_KEY'])
    @list_id = ENV['MAILCHIMP_NEWSLETTER_LIST_ID']
  end
  def call(user)
    @gibbon.lists(@list_id).members.create(
      body: {
        email_address: user.email,
        status: "subscribed",
        double_optin: false,
        # merge_fields: {
        #   FNAME: @user.first_name,
        #   LNAME: @user.last_name
        # }
      }
    )
  end
end

查看不同的解决方案，我还在#config/application.rb 中添加了该行

module Pyswebsitev1
  class Application < Rails::Application
    @config.autoload_paths += %W(#{config.root}/app/services)
    config.i18n.default_locale = :en
  end
end

当我做一个 Rails 控制台时 - ActiveSupport::Dependencies.autoload_paths 结果包括 /app/services

我还尝试了“Spring stop”，重新启动服务器并捆绑。

如果您有任何想法，那将非常有帮助！非常感谢

您忘记了_service文件名末尾的 。

_service如果你把它放在你的问题中，也许你忘了把它放在你的文件名事件中。只是猜测...
