Ruby on rails 斯芬克斯的思想有很多；你有很多吗

我需要索引这些关联：

Author has_many :contributions
Author has_many :books, through: :contributions

我试着像这样写我的索引：

ThinkingSphinx::Index.define :author, :with => :active_record do
  indexes books(:title), as: :book
end

但它没有工作的意图。有什么想法吗

编辑

当我尝试此解决方案或几乎所有其他解决方案时，我在rake ts:index:

任务：TOP=>ts:index
（通过使用--trace运行任务查看完整跟踪）

试试这个

ThinkingSphinx::Index.define :author, :with => :active_record do
  indexes books.title, :as => :title
end

编辑：

请在git中检查此问题

在books表中是否有一个名为title的列？您是否有任何错误消息可以帮助我们进一步分析？您是否运行了

rake ts:index

？首先使用

rake ts:stop

停止ts，然后运行

rake ts:configure

，然后运行

rake ts:start

最后

rake ts:index

。我觉得新的索引定义在sphinx配置中不可用。rake ts:stop似乎根本不起作用，当我调用它时，什么都没有发生，我必须通过ctl+C终止它，担心以前的帖子。请在git中检查此问题。
