Question

I have a model called Question and another one called Answer.

class Question(models.Model):     text = models.CharField(max_length=140)  class Answer(models.Model):      user = models.ForeignKey(User)     question = models.ForeignKey(Question)     uncertain = models.BooleanField()     text = models.CharField(max_length=30) 

Now I’d like to have a QuerySet questions which is equivalent to Question.objects.all() but including the currently logged in user’s answers. I’m almost completely sure that this could be accomplished by an explicit JOIN in SQL, but I’m certain there is a better way to do this using Django’s ORM.

So how would I do that?

EDIT: To clarify, I’d like to be able to loop through the QuerySet, e.g. for q in questions and then be able to see whether or not the user has answered it through something like q.answered which could be a boolean, or q.answer which could be the Answer object itself (or None).

Answer 1

Are you looking for something like this?

[ item.question for question in Answer.objects.filter(user=request.user) ] 

Or perhaps you want to do a

questions = Question.objects.all() for question in questions:     question.answer = question.answer_set.filter(user=request.user) 

I guess I’m not understanding the question and which direction you want to go…

EDIT: Ok, based on your edit, perhaps the latter… you can see if it’s an empty list or tack on a .count() and see if the value is greater than 0.
