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.
Thanks!
Phil
