Rails 5 ActionView :: Template ::错误发生在控制器中＃action：“嵌套事务”
我最近从4迁移到最新的5.1 rails（以及从thin到puma服务器）。我有一个不可重复的错误，我无法追踪它的来源。下面是一个示例应用程序回溯：Rails 5 ActionView :: Template ::错误发生在控制器中＃action：“嵌套事务”
app/views/reports/_transaction_dialog.html.erb:88:in `_app_views_report= s__transaction_dialog_html_erb___259516699_72100400'

我知道它不会说太多...它只是一个局部渲染。它发生在代码的各个地方，但通常在应用程序使用鳍状肢来检查功能可用性的地方。这里_transaction_dialog.html.erb：88有：
<% if $flipper[:schooling].enabled? current_user %> 我会尝试将其报告给flipper但也许有人有其他的想法？我使用章鱼进行数据库分片。下面Gemfile.lock的：

它看起来像我有两个相同的请求，其中一个失败，从ActiveRecord的'嵌套事务'错误（它是AR？类错误实际上是::的ActionView ::模板错误）......
我没有看到任何rails source“嵌套事务” ......
第一个问题是为什么在轨两个请求从同一个客户和几乎相同的第二个？
第二个问题是为什么这种并行请求确实失败？
...我已经寻找“嵌套事务”我所有的宝石的来源，我没有看到它 - 我无法找到该代码提出这一错误:(
回答：
我终于能够重现上发展这个错误：我双击造成两个几乎同时请求链接从升降舵的的PStore来了实际的“嵌套事务”错误
解决方案：
使用$ flipper.preload减少翻转的功能调用数（[]）与a功能的名字rray并加入5分钟ActiveSupportCacheStore缓存过的PStore
禁用连续链路的使用
要检查它是否是对生产有效的，但开发试验看好。
UPDATE1：它只是降低了断号的错误 - 需要通过修补脚蹼启用上的PStore线程安全选项
UPDATE2：https://github.com/jnunemaker/flipper/pull/334
