determining if a one-to-many relation exists

[Jim N]

Hi Djangoists,

I have a model "question" which has a one-to-many relationship with
"answer".

class Question(models.Model):
    text = models.TextField()

class Answer(models.Model):
    text = models.TextField()
    question = models.ForeignKey(Question)

I can't figure out how to construct a filter that will give me

- just questions where there isn't an answer
- just questions where there is an answer

Is this really easy and I'm just not seeing it?

Thanks,
Jim
