Rails console eats my query trace

I understand that the default since 3.1 is not to log to development.log
anymore and simply display SQL inline in the console (STDOUT). This is
fine
with me, and I know I can change it by reassigning the
ActiveRecord::Base.logger to e.g. Rails.logger.

However, I can’t seem to get any of the query tracing gems to show me
the
origin of the SQL queries (bullet, sql-logging, query_trace,
active-record-query-trace). As far as I can tell I’ve configured these
correctly and their config setting is enabled as true

For example, I’ve tried using this: https://gist.github.com/1942451

This should set up a log subscriber attached to ActiveRecord. However,
the
sql method in there never gets called. I’m not really sure what’s
happening. Has anyone had success or problems with this?

Thanks,
Andrew V.
