从delayed_job执行时,Ruby on Rails fb_graph失败,未定义方法字节大小

我正在使用omniauthdelayed_job的组合来与Facebook整合。我有一个Authentication模型看起来有点像这样:

class Authentication < ActiveRecord::Base

  def account
    @account ||= FbGraph::User.me(token)
  end

  def post_to!(opts = {})
    account.feed!(opts)
  end

end

然后从控制台我可以做到这样的事情:

auth.post_to :message => 'Foo bar', :link => 'http://google.com'

...一切正常,更新发布到我的Facebook Feed。

但是,在应用程序中,我创建了一个完全按照上述方式执行的自定义延迟作业,只有每次都出现以下错误堆栈时才会失败:

我已经正式开始将昂贵的计算机扔出窗外。任何人都可以提供任何关于它失败的原因,为什么它在从控制台执行时有效,但在从自定义delayed_job执行时失败?

非常感谢任何帮助。谢谢。

解决方案很简单。 您必须在代码中使用 to_str

auth.post_to message: message.to_str, link: 'http://google.com'
