modelformset partial save and AttributeErrors

[Michael Wayne Goodman]

Hi, I'm getting the following error when I try to assign a value to a
model attribute in a modelformset:

AttributeError at /number/
'WSGIRequest' object has no attribute 'qsession'

which occurs in the following snippet:

            numbers = formset.save(commit=False)
            for number in numbers:
                number.qsession = request.qsession
                number.save()

If I dir(number) I can see qsession as an attribute, which is
puzzling. I'm really bad at this stuff, so I'll put all the relevant
code below. Any help appreciated.

Here are the models:

class QuestionnaireSession(models.Model):
    user = models.ForeignKey(User,blank=True,null=True)
    name = models.CharField(max_length=100,blank=True,null=True)

class Number(models.Model):
    qsession = models.ForeignKey(QuestionnaireSession)
    name = models.CharField(max_length=100)
    supertype = models.ForeignKey('self',blank=True,null=True)

And the formset:

NumberFormSet = modelformset_factory(Number, exclude=('qsession',))

And the relevant views.py code:

def get_qsession(request):
    if 'qsession' not in request.session:
        qsession = QuestionnaireSession()
        qsession.save()
        request.session['qsession'] = qsession
    else:
        qsession = request.session['qsession']
    return qsession

def number(request):
    qsession = get_qsession(request)
    queryset = Number.objects.filter(qsession=qsession)
    if request.method == 'POST': # form was submitted
        formset = NumberFormSet(request.POST, queryset=queryset)
        if formset.is_valid():
            numbers = formset.save(commit=False)
            for number in numbers:
                number.qsession = request.qsession
                number.save()
            return HttpResponseRedirect('/top/')
    else:
        formset = NumberFormSet(queryset=queryset)
    return render_to_response('questionnaire/questionnaire.html',
                              {'numberformset': formset},
 
context_instance=RequestContext(request))

Thank you
