How does one enforce that any child record saved has a parent? I've got this:
Parent: has_one :child Child: belongs_to :parent So, Child records have a parent_id. If, in the Child model, I put: validates :parent_id, :presence => true I get a failure when I do this: c = Child.new p = Parent.new c.parent = p c.save! It fails the validation with "parent_id can't be blank". As if it's trying to save the child first, before the associated parent? If I take away the presence validation, it works fine. Or, if I leave the validation there, but save the two sides by hand: c = Child.new p = Parent.new p.save! c.parent = p c.save! It also seems to work. Is it just not smart enough to know it needs to save the parent first so it can get the id? Or am I just not smart enough to use what rails provides? :) Thanks for any thoughts... -glenn -- SD Ruby mailing list [email protected] http://groups.google.com/group/sdruby
