Ruby on Rails

I hate to reply to myself, but I narrowed it down to Rails caching by DEFAULT of model queries.  It can be worked around by passing 'true', like this:

tc.name = "something different"

tc.save!

tp.test_children.map {|x| x.name }.to_sentence # => "test1, test2, test3, and test4" *WRONG*

tp.test_children(true).map {|x| x.name }.to_sentence # => "test1, test2, test3, and something different" *CORRECT*

Another workaround is to just stop using has_many and such in favor of manual functions, a la:

 def test_children

  return TestChild.where(["test_parent_id = ?", self.id])

 end

Is there a way to turn this sort of caching off globally?  (Other caching is fine, I don't want to turn all caching off.)

BTW- It is a bit mind blowing that this is turned on by default.  Possible data corruption shouldn't ever be preferred by default over (possible) speed gains.  I'd still categorize this as a serious bug, at least as a configuration default.
