Question

我是新手编写代码以支持我正在开发的应用程序的第三方（Transaction Express）API调用。我一直在关注这个教程：https://revs.runtime-revolution.com/integrating-a-third-party-api-with-rails-5-134f960ddbba它对我有意义。但是，在尝试根据教程代码查看订阅者时，我收到以下错误。

收到错误：

无法自动加载常量Base，预计 /Users/xxxxxxxxx/Documents/projects/phrayme/xxxxxxxxxxx/app/services/base.rb 定义它

从我的研究中，我认为它可能与目录结构以及Rails期望在那里有什么关系，但我还没能找到问题所在。请指教。

subscribers_controller.rb

class SubscribersController < ApplicationController
   def index
     @subscribers, @errors = Transexp::Subscriber.random(query)
   end

   def show
     @subscriber = Transexp::Subscriber.find(params[:id])
   end

private

   def query
     params.fetch(:query, {})
   end
end

服务/ base.rb

module Transexp
  class Base
    attr_accessor :errors

    def initialize(args = {})
      args.each do |name, value|
        attr_name = name.to_s.underscore
        send("#{attr_name}=", value) if respond_to?("#{attr_name}=")
      end
    end
  end
end

服务/ subscriber.rb

module Transexp
  class Subscriber < Base
    attr_accessor :firstName,
                  :lastName,
                  :fullName,
                  :coName,
                  :phone_type,
                  :phone_nr,
                  :addrLn1,
                  :addrLn2,
                  :city,
                  :state,
                  :zipCode,
                  :ctry,
                  :email,
                  :type,
                  :stat,
                  :note

    MAX_LIMIT = 25

    def self.find(id)
      response = Request.get("subscribers/#{id}/information")
      Subscriber.new(response)
    end

    def self.random(query = {})
      response = Request.where('subscribers/random', query.merge({ number: MAX_LIMIT }))
      subscribers = response.fetch('subscribers', []).map { |subscriber| Subscriber.new(subscriber) }
      [ subscribers, response[:errors] ]
    end

    def initialize(args = {})
      super(args)
    end
  end
end
