Question

我有一个modelformset AddressFormSet = modelformset_factory(Address)。在我看来，我将此formset分配给不同的上下文变量，但它们似乎是重复的。输入名称相同。

def get_context_data(self, **kwargs):
    context = super(TravelCreate, self).get_context_data(**kwargs)
    if self.request.POST:
        context['address1'] = AddressFormSet(self.request.POST)
        context['address2'] = AddressFormSet(self.request.POST)
    else:
        context['address1'] = AddressFormSet(queryset=self.model.objects.none())
        context['address2'] = AddressFormSet(queryset=self.model.objects.none())
    return context

如何为它们指定不同的名称，以便两个formset中的数据都能创建对象。

从工厂创建时，您需要为两个Formset提供不同的前缀，否则它们将使用发布数据中的相同名称

def get_context_data(self, **kwargs):
    context = super(TravelCreate, self).get_context_data(**kwargs)
    if self.request.POST:
        context['address1'] = AddressFormSet(self.request.POST, prefix='address1')
        context['address2'] = AddressFormSet(self.request.POST, prefix='address2')
    else:
        context['address1'] = AddressFormSet(queryset=self.model.objects.none(), prefix='address1')
        context['address2'] = AddressFormSet(queryset=self.model.objects.none(), prefix='address2')
    return context
