【问题描述】:
我有以下模型和索引来使用曲目标题和艺术家姓名搜索曲目:
models/track.rb
class Track < ActiveRecord::Base
include ThinkingSphinx::Scopes
belongs_to :artist, :class_name => 'Fan', :foreign_key => 'fan_id'
sphinx_scope(:of_fan) do |fan_id|
{with: {fan_id: fan_id}}
end
def artist_name
artist.name
end
end
models/fan.rb
class Fan < User
has_many :tracks
end
models/user.rb
class User < ActiveRecord::Base
#Codes...
end
宝石清单:
gem 'rails', '4.1.0.rc1'
gem 'thinking-sphinx', '~> 3.1.3'
索引/track_index.rb
ThinkingSphinx::Index.define :track, :with => :active_record, :delta => true do
indexes title
has plays_count, :as => :play_count
end
我尝试使用以下所有选项重建索引,但没有任何效果并在此块下生成错误:
indexes artist(:first_name), :as => :artist_name
indexes artist.first_name, :as => :artist_name
indexes artist_name
indexes [artist.first_name, artist.last_name], :as => :artist_name
错误:
#For..
#indexes artist(:first_name), :as => :artist_name
#indexes artist.first_name, :as => :artist_name
ERROR: index 'track_delta': sql_range_query: ERROR: syntax error at or near "AS"
LINE 1: ..."title" AS "title", AS "author...

(DSN=pgsql://username:***@localhost:5432/db_name).
#For - indexes [artist.first_name, artist.last_name], :as => :artist_name
