思考狮身人面像,协会不起作用

我有一个模特:

class Topic < ActiveRecord::Base

  define_index do 
    indexes title, :sortable => true
    indexes body
    indexes tags(:name), :as => :tag_name
  end

  has_and_belongs_to_many :tags, :join_table => 'topic_tags', :order => 'tags.name asc'

end

当我跑步时:

rake ts:rebuild

我明白了:

sql_range_query: Unknown column 'topics.name' in 'field list'

我的'config / development.sphinx.conf'有这种奇怪之处:<​​/ p>

  sql_query = SELECT `topics`.`id` * 1 + 0 AS `id` , CAST(`topics`.`title` AS CHAR) AS 
`title`, CAST(`topics`.`body` AS CHAR) AS `body`, CAST(`topics`.`name` AS CHAR) AS 
`tag_name`, `topics`.`id` AS `sphinx_internal_id`, 1552019743 AS `class_crc`, '1552019743'
 AS `subclass_crcs`, 0 AS `sphinx_deleted`, IFNULL(`topics`.`title`, '') AS `title_sort` 
FROM `topics`    WHERE `topics`.`id` >= $start AND `topics`.`id` <= $end GROUP BY 
`topics`.`id`  ORDER BY NULL
  sql_query_range = SELECT IFNULL(MIN(`id`), 1), IFNULL(MAX(`id`), 1) FROM `topics`

因此,出于某种原因,协会看起来很破旧,我哪里出错,我该如何解决这个问题呢?

(运行导轨2.3.4和最新思考的sphinx 1.2.11)

1 个答案:

答案 0 :(得分:9)

琐碎陷阱:

这有效:

class Topic < ActiveRecord::Base
  has_and_belongs_to_many :tags, :join_table => 'topic_tags', :order => 'tags.name asc'

  define_index do 
    indexes title, :sortable => true
    indexes body
    indexes tags(:name), :as => :tag_name
  end



end
必须在索引之前定义

关联。
