Eager Loading Polymorphic Associations

Rails
#1

Hi,

I’m searching for a method of eager loading polymorphic associations
under
activerecord 2.0.2. After some initial google-fu I came up with a link
to
an enhancement that’s been added to edge:
http://dev.rubyonrails.org/ticket/8119

Anyone have any idea how long that might take to work its way into a
general
release? I’m early in development now so I can afford to wait a while
instead of introducing any dubious work arounds.

Thanks!

That patch is not in the current edge. Current edge has a
different :include mechanism (from ticket 9640) which does know how
to eager load polymorphic associations, so 2.1 will be able to do
this. I don’t have the faintest clue when 2.1 will be out, but if
running edge for now is an option then you might want to go with that
(or try and backport that patch to 2.0.2. I imagine it would apply
without too much difficulty, but then you’d also want to track down
any bug fixes made to it)

I should also point out that 9640 solves the problem in an entirely
different way
