Why is rails query caching not working? -


in development environment have single request generating hundreds of same queries:

person load (24.4ms)  select "persons".* "persons" ("persons"."person_id" = 517) limit 1   . . .    person load (64.4ms)  select "persons".* "persons" ("persons"."person_id" = 517) limit 1

why this? thought rails supposed enable query caching default on per request basis?

config/development.rb:   config.cache_classes = false   config.perform_caching = true     . . .     # show full error reports , disable caching   config.consider_all_requests_local       = true   config.action_view.debug_rjs             = true   config.action_controller.perform_caching = true   config.active_support.deprecation        = :log

if you're connecting multiple databases (say using establish_connection in models), appears activerecord::base.connection gets query caching enabled. not sure if that's case here, tricky side effect of connecting multiple dbs.
