Morning (as appropriate) all!
I’m having a problem with rails 2.0.1 and am hoping somebody here
might be able to help me out.
I’m building a flex/rubyamf/rails app, and I’m having trouble saving
object graphs. Here’s an example.
Model: Contest
has_many Prizes
Model: Prize
belongs_to Contest
has_many Wins
Model: Win
belongs to Prize
When I create my Contest, I am populating Prizes, however, I’m not
populating Wins. When I get to ContestsController.create and do
@contest.save it’s blowing up (stack below) because it doesn’t like
that @contest.prizes.wins is nil. There are no validations on wins,
and I really suspect I SHOULD be able to do this.
Anybody have an idea what might be wrong? I know that my objects are
good when they hit the controller, so it’s not rubyamf at this
point. . .that was a whole other story ; ) Here are the params and
dump:
