ActiveRecord association lazy reload?

Rails
1

If I want to reload an AR association, I can call “reload” on it.
department.employees.reload or what have you.

But what I want to do is uncache it, but not actually take a trip to the
db. I want to mark it so NEXT time it’s accessed, it will take a trip to
the db (if it is ever accessed again). I know it’s become unreliable,
but I don’t want to spend the time reloading it now, I want to just mark
it as uncached. Lazily reload it.

Any good way to do that in AR?

If it’s an association collection, then department.employees.reset
should do the trick. For has_one/belongs_to you need to fiddle with
innards.

Perfect, that meets my present needs, thanks.

Would be a useful enhancement to support reset/reload on to-one
relationships too, but for now this is what I need, thanks.
