I have a rails model that has multiple "has_many through" relationships. I defined these in active record and in the searchable block. When I define the relationship on a single-word model name (ex: Contributor) and re-index, it works fine. When I define the relationship on a 2-word model name (ex: LuSubject) and re-index, it does not work. I get the error "undefined method 'subject_ids'. I tried other models with the same result. "Award" works. "LuGrade" does not.

Here is the code from my "Work" model:

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

Here is the output of the reindex command

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

Here is my current version info

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

NOTE: I am working with production tables, so I don't have the option of renaming those tables.

Thanks.

Answer 1

Your setting of integer :subject_ids, ... will cause Sunspot to invoke a subject_ids method on your object. Some ActiveRecord associations will define a method like that based on a has_many association, but I don't see a has_many :subjects which would define that.

Did you mean integer :lu_subject_ids?
