I'm pretty sure this used to work pre-edge:
u = User.new
=> #<User id: nil, nickname: nil, created_at: nil, updated_at: nil>
l = u.listings.build
=> #<Listing id: nil, user_id: nil, title: nil, text: nil, created_at: nil, updated_at: nil>
l.user
=> nil
u.listings
=>
User/Listing have a very basic has_many/belongs_to relationship.
Am I imagining things, or did some of the recent changes to AR break something?
Thanks, Hendrik
