複数の「has_many through」関係を持つ Rails モデルがあります。これらをアクティブ レコードと検索可能ブロックで定義しました。1 語のモデル名 (例: Contributor) でリレーションシップを定義し、インデックスを再作成すると、正常に機能します。2 語のモデル名 (例: LuSubject) でリレーションシップを定義して再インデックスすると、機能しません。「undefined method 'subject_ids'」というエラーが表示されます。同じ結果で他のモデルを試しました。「Award」は機能しますが、「LuGrade」は機能しません。

私の「仕事」モデルのコードは次のとおりです。

class Work < ActiveRecord::Base

  self.table_name = 'work'
  self.primary_keys = :WORK_ID  

  alias_attribute :work_id, :WORK_ID
  alias_attribute :title, :TITLE
  alias_attribute :series_id, :SERIES_ID 


  has_many :work_contributors, :foreign_key => :WORK_ID
  has_many :contributors, :through => :work_contributors
  has_many :work_grades, :foreign_key => :WORK_ID
  has_many :lu_grades, :through => :work_grades  
  has_many :work_primary_subjects, :foreign_key => :WORK_ID
  has_many :lu_subjects, :through => :work_primary_subjects  
  has_many :work_awards, :foreign_key => :WORK_ID
  has_many :awards, :through => :work_awards
  belongs_to :series, :foreign_key => :SERIES_ID

  searchable do
    text :title 

    integer :work_id 
    string :title
    integer :series_id 
    integer :contributor_ids, :references => Contributor, :multiple => true
    integer :subject_ids, :references => LuSubject, :multiple => true
  end

reindex コマンドの出力は次のとおりです。

$ bundle exec rake sunspot:reindex 
rake aborted!
undefined method `subject_ids' for #<Work:0x00000003bee760>

ここに私の現在のバージョン情報があります

$ gem list|grep sunspot
sunspot (1.3.3)
sunspot_rails (1.3.3)
sunspot_solr (1.3.3)

注: 私は実稼働テーブルで作業しているため、これらのテーブルの名前を変更するオプションはありません。

ありがとう。

の設定によりinteger :subject_ids, ...、Sunspot はsubject_idsオブジェクトのメソッドを呼び出します。一部の ActiveRecord アソシエーションは、アソシエーションに基づいてそのようなメソッドを定義しますが、それを定義する は見当たりhas_manyませんhas_many :subjects。

ということinteger :lu_subject_idsですか？
