Thinking Sphinx 3.1.4 ActiveRecord::ConfigurationError on indexing

Question

我在 Rails 3.2.21 和 Thinking-Sphinx 3.1.4 上使用 Sphinx 2.2.9-id64-release (rel22-r5006)。

我刚从 mysql 转移到 postgres，当我索引时出现此错误：

production@vagrant:/opt/rails/production/current$ rake ts:index --trace

** Invoke environment (first_time)

Tasks: TOP => ts:index

我将索引缩小到仅有的两个可能导致错误的条目，它似乎与多态关系有关：

ThinkingSphinx::Index.define(:project, name: 'project', with: :active_record, delta: true) do
  indexes data.itemcode, as: :itemcode

  polymorphs data, to: PROJECT_DATA_TYPES.map(&:camelize)
end

知道为什么这不起作用吗？

Answer 1

按照您的堆栈跟踪，您正在使用 Rails 3.2 和 Thinking Sphinx 3.1.4 - 在 TS v3.1.4 中删除了对 Rails 3.2 的多态关联支持（如 the release notes 的“升级”部分所述）。 ActiveRecord 的内部代码会定期更改，对于该特定功能同时支持 3.2 和 4.x 实在是太痛苦了。

如果您刚刚升级了 TS 并且有一个可以运行的早期版本，您可能需要切换回该版本。还是升级到 Rails 4.0？ :)
