在 Think sphinix rails 3.2.14 中拥有并属于许多关联搜索

Question

我正在使用Rails 3.2.14、thinking-sphinx 3.1.1 和Sphinx 2.2.4-id64-release (r4806)

我在下面有两个模态：-

Album.rb
  has_and_belongs_to_many :genres

Genre.rb
  has_and_belongs_to_many :albums

所以关联表是albums_genres

我想使用genre_id搜索相册

Example: 当我通过genre_id 时，它应该根据第三张表albums_genres 返回与genre_id 关联的所有专辑

我试过这样

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!

Answer 1

看起来这是 Rails 3.2、:source => :query 和 HABTM 连接的一个错误（遗憾的是，这并不奇怪 - 即使在 Rails 4.0 上让代码工作也是痛苦和脆弱的）。

恐怕您的选择是升级到 Rails 4 或不使用 :source => :query 选项（我知道这意味着您失去了一些不错的索引速度增益）。

我在不久的将来得到一个补丁的可能性很小（但如果他们愿意，欢迎其他人试一试）。
