我注意到我的查询没有被缓存。我跑bundle exec rake middleware | grep Cache，它是空的。我尝试在config/application.rb中添加以下内容：
config.middleware.use ActiveRecord::QueryCache
但是，我得到：
rake aborted!

我以为默认情况下应该启用查询缓存？为什么没有启用？如何启用它？
我正在使用 WSL。
查询缓存在轨道中的工作方式不同。它仅在请求内部应用，缓存在请求结束时被销毁，它不会在请求之间保持活动状态。
请参阅 SQL 缓存 https://guides.rubyonrails.org/caching_with_rails.html#sql-caching 的轨道指南
但是，请务必注意，查询缓存在操作开始时创建，并在操作结束时销毁，因此仅在操作持续时间内保留。如果要以更持久的方式存储查询结果，可以使用低级别缓存。
如果要在请求之间保留查询缓存，则必须使用低级别缓存自行实现它 https://guides.rubyonrails.org/caching_with_rails.html#low-level-caching
