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. On 13 March 2010 16:54, Max Williams <[email protected]> wrote: > Hi.
