Our approach up to now has been to blacklist request parameters from the Rails logs. We've been directed to ensure that no PII makes its way into these logs, so this switches the approach to whitelisting, by default only logging the controller, action, and id.
Rails's method of doing this is pretty janky, letting you specify a block that must modify the parameters in-place. Under test, the parameters can be symbols, which one cannot modify in-place, although this does not seem to be the case in the app server.
