Cache?

[atomless]

Hi, I'm look into how to get activerecord query cache working otr.
After adding this to my config.ru:

use ActiveRecord::QueryCache

On starting my server I now see this error :

Any ideas? Have you had activerecord query cache working otr?

[atomless]

I found one solution is to add this after a connection has been established:

ActiveRecord::Base.connection.enable_query_cache!

But wonder if there's a better way ?

The recommended answer is use OTR::ActiveRecord::QueryCache,
