ruby-on-rails – 通过delayed_job使用Gibbon gem时出错？

Rails 3.0.7,Gibbon 0.1.5(用于处理MailChimp的gem),delayed_job 2.1.4.

调节器

def subscribe
  email = params[:email]
  EmailNewsletter.subscribe(email)
  render(:update) do |page|
    page << "...view update code..."
  end
end

LIB / email_newsletter.rb

module EmailNewsletter
  def self.subscribe(email)
    g = Gibbon::API.new('api_key_here',:id => 'list_id_here')
    g.listSubscribe(:email_address => email)
  end
end

使用上面的代码,如果我向/ subscribe发布电子邮件地址,一切正常.我想合并delayed_job,以便我的应用程序不会感到缓慢,如果MailChimp花了太长时间来响应.

调节器

def subscribe
  email = params[:email]
  EmailNewsletter.delay.subscribe(email)
  render(:update) do |page|
    page << "...view update code..."
  end
end

看起来这个工作进入delayed_job表就好了.处理程序数据是：

--- !ruby/struct:Delayed::PerformableMethod 
object: !ruby/module EmailNewsletter
method_name: :subscribe
args: 
- email@example.com

一秒钟后,工人拿起并运行,我收到一个错误：未初始化的常量EmailNewsletter :: Gibbon.

application.rb包括config.autoload_paths =％W(#{Rails.root} / lib).

我究竟做错了什么？

编辑

为了澄清,错误被抛出的那一行是

g = Gibbon :: API.new(‘api_key_here’,：id =>’list_id_here’)

我也试过了

g = :: Gibbon :: API.new(‘api_key_here’,：id =>’list_id_here’)
