如何动态地向表单添加两个内联表单集？

Question

在管理页面中，它可以轻松完成，但是在查看页面中似乎存在问题。我已经尝试过但是失败了很多次。因为我是django的新手。如何在“自定义视图”页面中实现这种类型的表单集？ （同时创建和更新） 我将jQuery插件用于动态FormSet。这是我在views.py

中的代码

class ExamAdd(CreateView):
    model = Exam
    fields = ['title', 'examRoom']
    success_url = reverse_lazy('index')

    def get_context_data(self, **kwargs):
        data = super(ExamAdd, self).get_context_data(**kwargs)
        print('This is data for exam add',data)
        if self.request.POST:
            data['dateformset'] = ExamDateFormSet(self.request.POST)
            data ['shiftformset'] = ExamShiftFormSet(self.request.POST)
        else:
            data['dateformset'] = ExamDateFormSet()
            data['shiftformset'] = ExamShiftFormSet()
        return data

    def form_valid(self, form):
        context = self.get_context_data()
        dateformset = context['dateformset']
        shiftformset = context ['shiftformset']
        with transaction.atomic():
            self.object = form.save()

            if dateformset.is_valid() and shiftformset.is_valid():
                dateformset.instance = self.object
                shiftformset.instance = self.object
                instances  = dateformset.save(commit = False)
                for instance in instances:
                    instance.save()
                instances  = shiftformset.save(commit = False)
                for instance in instances:
                    instance.save()
                invigilatorAssignment = InvigilatorAssignmentForm()
        return super(ExamAdd, self).form_valid(form)



class ExamUpdate(UpdateView):
    model = Exam
    fields = ['title', 'examRoom']
    success_url = reverse_lazy('index')
    examDateFormSet = inlineformset_factory(Exam,ExamDate,form = ExamDateAddForm,formset=BaseExamDateEditFormSet2,extra = 1,can_delete=True)
    examShiftFormSet = inlineformset_factory(Exam,Shift,form = ExamShiftAddForm,formset = BaseShiftEditFormSet2,extra = 1,can_delete=True)

    def get_context_data(self, **kwargs):
        data = super(ExamUpdate, self).get_context_data(**kwargs)
        if self.request.POST:
            data['dateformset'] = self.examDateFormSet(self.object,self.request.POST)
            data ['shiftformset'] = self.examShiftFormSet(self.object,self.request.POST)
        else:
            data['dateformset'] = self.examDateFormSet(self.object)
            data['shiftformset'] = self.examShiftFormSet(self.object)
        print ("This is data",data)
        print ("THis is objetc",self.object)
        return data

    def form_valid(self, form):
        context = self.get_context_data()
        dateformset = context['dateformset']
        shiftformset = context ['shiftformset']
        with transaction.atomic():
            self.object = form.save()

            if dateformset.is_valid() and shiftformset.is_valid:
                if dateformset.has_changed():
                    dateformset.instance = self.object
                    dateformset.save()
                if shiftformset.has_changed():
                    shiftformset.instance = self.object
                    shiftformset.save()
                invigilatorAssignment = InvigilatorAssignmentForm()
            else:
                print ("DateFormSet Not Valid",dateformset.errors)
                print ("ShiftFormSet Not Valid",shiftformset.errors)
        return super(ExamUpdate, self).form_valid(form)

和模板中。
