Hi,
I'm not sure 100% what you're trying to do but the presence of question_id will not be there until the record has been saved. No?
And I'm not sure why you're doing this .... @grading = @question.gradings.build(more_attributes)
Shouldn't you have done a build before presenting your form if you have nested forms?
Maybe you could teach me something on what you're trying to do.

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
