Question

我有一个有多个“has_many through”关系的rails模型。我在活动记录和可搜索块中定义了这些。当我在单字模型名称上定义关系时（例如：贡献者）和重新索引，它工作正常。当我在2字模型名称上定义关系时（例如：LuSubject）和重新索引，它不起作用。我收到错误“未定义的方法'subject_ids'。我尝试了其他具有相同结果的模型。 “奖”有效。 “LuGrade”没有。

以下是我的“工作”模型中的代码：

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

这是reindex命令的输出

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

Tasks: TOP => sunspot:reindex
(See full trace by running task with --trace)

这是完整的痕迹

这是我当前的版本信息

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

注意：我正在使用生产表，因此我没有重命名这些表的选项。

感谢。

您integer :subject_ids, ...的设置将导致太阳黑子在您的对象上调用subject_ids方法。一些ActiveRecord关联将基于has_many关联定义类似的方法，但我没有看到定义该关联的has_many :subjects。

您的意思是integer :lu_subject_ids吗？

Rails3太阳黑子：reindex - rake aborted！未定义的方法
