ruby-on-rails - 未初始化的常量 Gibbon::Request (NameError)

Question

我正在尝试使用 Gibbon 和 Mailchimp 进行基本邮件列表设置。

当我启动我的 rails 服务器 rails s

时，我经常遇到这个错误

我什至降级到版本 gem 'gibbon', '~>1.2.0'

但是我的日志还是这个样子

我一直在关注这个链接 http://cheshireoctopus.github.io/blog/2014/01/23/mailchimp-plus-gibbon-plus-rails-create-a-basic-sign-up-form/

还有这个http://aspiringwebdev.com/e-mail-in-rails-with-mailchimp-and-mandrill-a-comprehensive-guide/

我已经根据 stackoverflow 帖子做了各种修改，但似乎仍然没有任何效果。

我不知道这里发生了什么，但如果有人能给我建议会很有帮助......

这是我的config/initializers/gibbon.rb

 require 'gibbon'
  gibbon = Gibbon::Request.new(api_key: "myAPIkey")
  Gibbon::API.timeout = 15
  Gibbon::API.throws_exceptions = false

emailapi_controller.rb

 class EmailapiController < ApplicationController
  def index
  end

  def subscribe

   @list_id = "myLISTid"
   gb = Gibbon::API.new

   gb.lists.subscribe({
   :id => @list_id,
   :email => {:email => params[:email][:address]}
   })

  end
end

Answer 1

如果有人感兴趣，我设法通过执行以下操作解决了这个问题。

在 Gemfile 中，我将 gem 'Gibbon' 更改为 gem 'gibbon', :git => 'https://github.com/amro/gibbon.git'

然后我将 emailapi_controller.rb 更改为

class EmailapiController < ApplicationController
 def subscribe
   @list_id = ENV["MAILCHIMP_LIST_ID"]
 gibbon = Gibbon::Request.new

gibbon.lists(@list_id).members.create(
  body: {
    email_address: params[:email][:address],
    status: "subscribed"
  }
)

respond_to do |format|
  format.json{render :json => {:message => "You have been Successfully added to the list! :)"}}
    end
  end
end

initializers/gibbon.rb 应该是这样的:

 Gibbon::Request.api_key = ENV["MAILCHIMP_API_KEY"]
 Gibbon::Request.timeout = 15
 Gibbon::Request.throws_exceptions = false

MAILCHIMP_API_KEY 和 MAILCHIMP_LIST_ID 存储在由 figaro gem 创建的 application.yml

希望这对遇到同样错误的人有所帮助。
