I was talking with a friend of mine last week about the new Rails deprecation warnings that you’ll see when you do naughty things like access @cookies from your controller or use deprecated methods like ActiveRecord’s find_all. Sometimes it’s useful to turn off those warnings – especially when they’re coming from a part of your application you don’t control (i.e. a third-party library).

To turn off all deprecation warnings, just do the following:

ActiveSupport::Deprecation.silenced = true

Or, if you want to perform something other than spit out deprecation warnings you can re-route them however you want within a block:

ActiveSupport::Deprecation.behavior = Proc.new { |msg, stack| MyLogger.warn(msg) }

def bad_action
  ActiveSupport::Deprecation.silence { p "Referencing #{@cookies} is bad" }
end

Hopefully this will get you past any annoying deprecations you can’t do much about (without giving you an easy out for those that you can do something about).
