我正在使用Rails 3.2.14，thinking-sphinx 3.1.1和Sphinx 2.2.4-id64-release (r4806)
我有两种模式： -
Album.rb
has_and_belongs_to_many :genres
Genre.rb
has_and_belongs_to_many :albums
因此关联的表格为albums_genres
我想使用genre_id
Example:当我传递genre_id时，它应该根据第三个表genre_id
albums_genres相关联的所有相册
我试过那样的
ThinkingSphinx::Index.define :album, :with => :active_record do
#other indexes
has genres.id, :as => :genre_ids, :source => :query
end
但是当我以rake ts:index运行rake任务时，我得到的错误是： -
rake aborted!
undefined method `join_table' for #<ActiveRecord::Reflection::AssociationReflection:0x000000079224d8>

看起来这是Rails 3.2，:source => :query和HABTM加入的错误（遗憾的是，即使使用Rails 4.0使代码工作也很痛苦且非常脆弱）。
我担心您的选项要么升级到Rails 4，要么不使用:source => :query选项（我知道这意味着您会因索引而失去一些不错的速度增益）。
我在不久的将来获得补丁的几率很小（但如果他们愿意的话，欢迎其他人试一试）。
