Order.products << product w/out persisting

Rails
1

Hi,
I have a one-to-many relationship. I want to be able to add objects
to the collection w/out persisting them. How do I do this?

The only thing I can’t think of is to use a transaction and roll it
back.

In other words - I want to do this:

o = Order.find(1)
p = Product.find(1)
o.products << p # but don’t persist this

I assume I’m just missing something obvious here. Any ideas?
Thanks,
Ben

Hm, maybe clone/dup the object?

o.products.to_ary << p

yes, but I still want it to be there as an unpersisted member, so I
get it when I do

o.products.each do |p|
…
end

Hmm, I’m surprised this doesn’t work.
