将 rails2 应用程序迁移到 rails 3，难以思考 sphinx 索引运行

Question

rails 2.3.10 正在迁移到 rails 3.2.18。它完全围绕全文索引。 rails 2 版本在 postgresql 9.0.4 上运行，而迁移版本在 9.3.5 上运行

数据表被移植到新的 rails 3 版本而没有错误。我确实有几个模型需要一些改进，但不是与这个问题/案例相关的对象。

rake ts:configure 

生成 sphinx.conf 文件。它看起来与原生 rails3 sphinx/thinking-sphinx 应用略有不同。

source filodiretto_core_0
{
  type = pgsql
  sql_host = localhost
  sql_user = jerdvo
  sql_pass = 
  sql_db = fna_development
  sql_query_pre = SET TIME ZONE UTC
  sql_query = SELECT "filodirettos"."id" * 24 + 0 AS "id", "filodirettos"."titolo" AS "titolo", "filodirettos"."domanda" AS "domanda", "filodirettos"."data" AS "data", "filodirettos"."risposta" AS "risposta", "filodirettos"."id" AS "sphinx_internal_id", 'Filodiretto' AS "sphinx_internal_class", 0 AS "sphinx_deleted" FROM "filodirettos"  WHERE ("filodirettos"."id" BETWEEN $start AND $end) GROUP BY "filodirettos"."id", "filodirettos"."titolo", "filodirettos"."domanda", "filodirettos"."data", "filodirettos"."risposta", "filodirettos"."id"
  sql_query_range = SELECT COALESCE(MIN("filodirettos"."id"), 1), COALESCE(MAX("filodirettos"."id"), 1) FROM "filodirettos" 
  sql_attr_uint = sphinx_internal_id
  sql_attr_uint = sphinx_deleted
  sql_attr_string = sphinx_internal_class
  sql_query_info = SELECT "filodirettos".* FROM "filodirettos"  WHERE ("filodirettos"."id" = ($id - 0) / 24)
}

index filodiretto_core
{
  type = plain
  path = /Users/jerdvo/r/fna/shared/sphinx/filodiretto_core
  docinfo = extern
  charset_type = utf-8
  min_infix_len = 2
  enable_star = 1
  source = filodiretto_core_0
}

但是当我启动时

rake ts:index

所有索引都失败了

indexing index 'filodiretto_core'...
ERROR: source 'filodiretto_core_0': unknown type 'pgsql'; skipping.
ERROR: index 'filodiretto_core': failed to configure some of the sources, will not index.
[...] skipping non-plain index 'filodiretto'...

相对的“_index.rb”文件状态

ThinkingSphinx::Index.define :filodiretto, :with => :active_record do
    indexes titolo
    indexes domanda
    indexes data
    indexes risposta
end

我遇到了一个带有本机 rails3 应用程序的 pg_dump 文件。唯一的区别是在文件的顶部，来自 rails 2（和 postgres 9.0.4）的版本状态（在开头）

--
-- Name: crc32(text); Type: FUNCTION; Schema: public; Owner: jerdvo
--

CREATE FUNCTION crc32(word text) RETURNS bigint
    LANGUAGE plpgsql IMMUTABLE
    AS $$
          DECLARE tmp bigint;
          DECLARE i int;
          DECLARE j int;
          DECLARE byte_length int;
          DECLARE word_array bytea;

我不知道这个 'pgsql' 错误是从哪里来的。

您的 Sphinx 副本似乎没有安装 PostgreSQL 支持。您应该使用适当的标志重新安装它 - 如果是 compiling manually，则为 --with-pgsql，或者在通过 Homebrew 安装时使用 --pgsql。还需要 MySQL 支持，但可能已经自动应用了？
