Hi, people!
I want to write a view, which save all my data, entered to form.(like contrib.admin) But I got a problem. How to get a pk value of parent form, when it's just saved(form is continue editing)? I have such models: ###### class Question(models.Model): number = models.IntegerField() question = models.TextField() class Choice(models.Model): question = models.ForeignKey('Question') description = models.CharField(max_length=255) class QuestionForm(forms.ModelForm): class Meta: model = Question ChoiceQuestionFormSet = inlineformset_factory (Question,Choice,extra=1,can_delete=True) ####### def cat4_view(request): if request.method == 'POST': uform = QuestionForm(request.POST,prefix='question',) choice_formset = ChoiceQuestionFormSet(request.POST, request.FILES, instance=uform.instance,prefix='choice',) # #uform.insnace is always None ! # print dir(uform) print uform.instance print dir(uform.instance) print uform.instance.pk print uform.instance.id print uform.instance.question assert False if uform.is_valid(): number = uform.cleaned_data['number'] description = uform.cleaned_data['question'] try: q = Question.objects.get(number = number) q.question = description q.save() except Question.DoesNotExist: Question.objects.filter(number = number).delete() q = Question(number = number,question = description) q.save() if choice_formset.is_valid(): choice_formset.save() else: choice_formset = ChoiceQuestionFormSet(prefix='choice',) uform = QuestionForm(initial={},prefix='question',) return render_to_response('form.html',{'form': uform, 'formset':choice_formset}) ##### In these example instance=uform.instance is always null, even I just save a model and make a mistake in some field. (submit is worked as 'save and conitue edit') How can I recognize a instance object's pk for "choice_formset = ChoiceQuestionFormSet(request.POST, request.FILES, instance=uform.instance,prefix='choice',)" igor. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
