Question

I have the relationship follow as:

class Question(models.Model):
  qid = models.PositiveIntegerField(primary_key=True)
  content = models.CharField(max_length=128)

class Answer(models.Model):
  answerid = models.PositiveIntegerField(primary_key=True)
  content = models.CharField(max_length=128)
  question = models.ForeignKey(Question)

I want to find the questions, which have the answer. How can I do it?
Please help me to solve this problem.
Thank you so much.

If you are trying to find all the questions that have answers:

Question.objects.filter(answer__isnull=False).distinct()
