Django Formset的DetailView

Question

我第一次使用Django inlineformsets，而我正试图处理我的观点。我已经能够创建我的创建和更新视图，但我对如何进行详细信息视图感到迷茫。我基本上有2个模型 - SchoolMain和SchoolSub与SchoolSub与SchoolMain建立了fk关系。 SchoolSub是我的表格。我的创建视图位于 -

之下

class SchoolSubCreate(LoginRequiredMixin,UserPassesTestMixin,generic.CreateView):
    model = SchoolMain
    fields = '__all__'

    def get_context_data(self, **kwargs):
        data = super(SchoolSubCreate, self).get_context_data(**kwargs)
        if self.request.POST:
            data['schoolsub'] = SchoolSubFormSet(self.request.POST)
        else:
            data['schoolsub'] = SchoolSubFormSet()

    def form_valid(self, form):
        context = self.get_context_data()
        schoolsub = context['schoolsub']
        with transaction.atomic():
            form.instance.user = self.request.user
            self.object = form.save()

            if schoolsub.is_valid():
                schoolsub.instance = self.object
                schoolsub.save()
        return super(SchoolSubCreate, self).form_valid(form)

我理解如何创建一般的DetailView，但这只能获取我的主要模型的对象，即SchoolMain模型。但是我无法访问formset中的对象。非常感谢任何帮助。感谢。
