我正在使用 Facebook 的组合omniauth并delayed_job与 Facebook 集成。我有一个Authentication看起来有点像这样的模型：

class Authentication < ActiveRecord::Base

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

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

end

那么从控制台我可以做这样的事情：

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

... 一切正常，更新已发布到我的 Facebook 提要。

但是，在应用程序中，我创建了一个完全执行上述操作的自定义延迟作业，只是每次都会失败，并出现以下错误堆栈：

undefined method `bytesize'' for nil:NilClass

我已经正式到了开始将昂贵的计算机扔出窗外的地步。任何人都可以提供任何关于它为什么失败的见解，为什么它在从控制台执行时工作但在从自定义延迟作业执行时失败？

任何帮助是极大的赞赏。谢谢你。

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'
