Rails 4.1 和 Thinking Sphinx - ActiveRecord::Associations::JoinDependency::JoinAssociation 的未定义方法“父”答案

【问题标题】：Rails 4.1 and Thinking Sphinx - undefined method 'parent' for ActiveRecord::Associations::JoinDependency::JoinAssociationRails 4.1 和 Thinking Sphinx - ActiveRecord::Associations::JoinDependency::JoinAssociation 的未定义方法“父”
【发布时间】：2014-06-09 08:06:05
【问题描述】：

我开始将Rails 4.0 应用升级到Rails 4.1。应用程序使用了很多宝石，Thinking Sphinx 就是其中之一。我在 Rails 4.1 升级后重新安装了thinking-sphinx gem（以启用正确版本的连接器，现在是3.0）。但是现在当我尝试重建索引时，我会收到来自 TS 的奇怪错误：

$ rake ts:rebuild --trace

** Execute environment

searchd is not currently running.

补充资料：

Rails 4.1
Sphinx 2.1.4 版本 (rel21-r4421)
thinking-sphinx 3.1.1
mysql2 0.3.16（狮身人面像）
pg 0.17.1（这是我的主数据库）

任何想法如何处理？我无法升级到新的 Rails，因为该项目使用 TS 非常重。

【解决方案1】：

好的，Thinking Sphinx 和 Rails 4.1 存在问题。当您使用 Rails 4.1 时，Thinking Sphinx 中的多态关联被破坏（因为 ActiveRecord 中发生了很多变化）。这是我打开的问题：https://github.com/pat/thinking-sphinx/issues/783

就我而言，我刚刚从多态关联迁移，因为我希望能够完全升级到 Rails 4.1。

UPD：Pat 解决了这个问题，现在应该可以了。
