Hi. I'm using rails 2.3.4 and have this association between two of my
models.

Question
has_many :gradings

Grading
belongs_to :question

Grading has this validation:
validates_presence_of :question_id

And this validation test is stopping me from doingg this, which i would
normally expect to work

@question = Question.new(attributes)
@grading = @question.gradings.build(more_attributes)
@question.save #fails because grading has no question_id

Now, i thought that this would work ok because (in my understanding) the
question is saved and then it saves it's built associated objects. How
can i ensure this will work? Do i need to drop the validation? I'd
rather not if possible.

Grateful for any advice - max
