django - 在 formset.save() 上设置表单集的外键

Question

很简单 - 我想要做的就是设置谁回答了问题(如果问题得到回答)。如果问题得到解答，有人可以告诉我如何设置表单值吗？我知道我也可以将其设置为初始值，但随后我必须有选择地确定哪些记录已得到答复。这看起来更简单，但我正在费尽心思试图弄清楚这一点。有人可以帮我吗。

模型足够简单

class ProjectQuestion(models.Model):
    question = models.CharField(max_length=255, editable=True)
    answer_type = models.CharField(max_length=50, choices=VALUE_TYPE_CHOICES, editable=True)
    answer = models.CharField(max_length=255, null=True, blank=True)
    answer_comment = models.TextField(blank = True, null = True)
    answered_by = models.ForeignKey(Employee, related_name="answered_by_test", null=True, blank=True)
    answer_date = models.DateTimeField(auto_now = True, null=True)
    objects = models.Manager()


    def __unicode__(self):
        return u'%s' % (self.question)

并且表示 View 也很简单。

# views.py
if request.method == "POST":
    print request.POST
    print request.user
    formset = QuestionFormSet(data=request.POST, files=request.FILES,
                              queryset=ProjectQuestion.objects.filter(id__lt=shortname))
    print formset.forms
    if formset.is_valid():
        person =  Employee.objects.get(name__iexact = request.user.get_full_name())
        for i in range(0, formset.total_form_count()):
            form = formset.forms[i]
            if form.cleaned_data['answer']:
                # THIS DOESN'T WORK...  PLEASE FIX..
                form.save(commit=False)
                form.answered_by = person
                form.save()
else:
    active_section = ProjectQuestion.objects.filter(id__lt=shortname)

Answer 1

这不是应该的吗

if form.cleaned_data['answer']:
    # THIS DOESN'T WORK...  PLEASE FIX..
    question = form.save(commit=False)
    question.answered_by = person
    question.save()
