Django 内联表单集验证

Question

我有以下型号：

class CaseForm(ModelForm):
    class Meta:
        model = Case
        fields = '__all__'


class ClientForm(ModelForm):

    class Meta:
         model = Client
         fields = '_all__'

CaseClientFormset = inlineformset_factory(Case, Client, form=ClientForm,
                                      extra=0, max_num=2, min_num=1,
                                      validate_max=True,
                                      validate_min=True)

当我填写表格（caseform）的顶部时，它会正确保存。当我填写caseform和clientform时，它会正确保存。

如果我填写了caseform但部分填写了clientform，则似乎不会进行任何验证，并且会保存一个案例，并且客户信息会丢失并且永远不会保存。

class CaseCreateView(LoginRequiredMixin, AdviserExistenceMixin,
                 CreateView):
    model = Case
    form_class = CaseForm

    def form_valid(self, form):
        context = self.get_context_data()
        clients = context['clients']
        self.object = form.save()

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

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        if self.request.POST:
            context['clients'] = CaseClientFormset(self.request.POST)
        else:
            context['clients'] = CaseClientFormset()

        context['navbar'] = str(self.model.__name__).lower()
        return context

我遇到的另一个问题是，尽管指定了 min_num=1 和 validate_min=True，但我似乎能够在不填写客户表单的情况下保存案例。

任何帮助将不胜感激。

修复了将 def form_valid 替换为：

def form_valid(self, form):
    context = self.get_context_data()
    clients = context['clients']

    if clients.is_valid():
        self.object = form.save()
        clients.instance = self.object
        clients.save()
        return super(CaseUpdateView, self).form_valid(form)
    else:
        return super(CaseUpdateView, self).form_invalid(form)
