Ruby on Rails 3 - 思考狮身人面像在Capistrano部署后失败"unknown key name 'sql_attr_string'"

Question

Thinking Sphinx在我的Rails应用程序开发环境中像做梦一样工作。但是，当我尝试通过Capistrano将它部署到我的生产环境中时，它失败了。我试着进去手动构建索引，结果出现了最奇怪的错误：

myuser@myhost:/domains/myappname.com/current$ bundle exec rake RAILS_ENV=production ts:index
Generating Configuration to /domains/myappname.com/releases/20130207221841/config/production.sphinx.conf
Sphinx 0.9.9-release (r2117)
Copyright (c) 2001-2009, Andrew Aksyonoff
using config file '/domains/myappname.com/releases/20130207221841/config/production.sphinx.conf'...
ERROR: unknown key name 'sql_attr_string' in /domains/myappname.com/releases/20130207221841/config/production.sphinx.conf line 27 col 18.
FATAL: failed to parse config file '/domains/myappname.com/releases/20130207221841/config/production.sphinx.conf'

查看.conf文件的相关部分，我没有看到任何特别奇怪的东西：

source piece_core_0
{
  type = mysql
  sql_host = localhost
  sql_user = [user redacted]
  sql_pass = [pass redacted]
  sql_db = [db redacted]
  sql_query_pre = SET NAMES utf8
  sql_query_pre = SET TIME_ZONE = '+0:00'
  sql_query = SELECT SQL_NO_CACHE `posts`.`id` * CAST(2 AS SIGNED) + 0 AS `id` , `posts`.`title` AS `title`, `posts`.`body` AS `body`, `users`.`name` AS `author_name`, `post$
  sql_query_range = SELECT IFNULL(MIN(`id`), 1), IFNULL(MAX(`id`), 1) FROM `posts`
  sql_attr_uint = sphinx_internal_id
  sql_attr_uint = sphinx_deleted
  sql_attr_uint = class_crc
  sql_attr_string = sphinx_internal_class
  sql_query_info = SELECT * FROM `posts` WHERE `id` = (($id - 0) / 2)
}

有什么解释吗？我只是不明白sphinx怎么会不理解它自己的配置文件中正常的部分（sql_attr_string）。这个错误是真正的错误吗？还是它指向了其他问题？

Answer 1

您似乎在使用Sphinx0.9.9版本（r2117）

根据斯芬克斯文件，sql_attr_string仅在1.10-beta版本中引入。

请检查您的生产环境，并使用更新的版本来使用此功能。
