Python Django-（隐藏字段顺序）内联外键与父实例主键不匹配

其他类似的问题并没有解决我的问题

我收到了错误消息：

（隐藏字段顺序）内联外键与父实例主键不匹配。

当试图从编辑表单（即已有数据）保存时。在我的视图中，我有另一种保存新数据的方法

my views.py：

def order_edit(request, order_id):
if request.POST:
    form = OrderForm(request.POST)
    if form.is_valid():
        order = form.save(commit=False)
        drink_formset = DrinkFormSet(request.POST, instance=order)
        if drink_formset.is_valid():
            OrderService.save_order(order, drink_formset)
            return HttpResponseRedirect(reverse('coffee:dashboard'))
else:
    order = OrderService.load_order(order_id, request)
    form = OrderForm(instance=order)
    drink_formset = DrinkFormSet(instance=order)
return render(request, 'coffee/order_edit.html', {
    'form': form,
    'drink_formset': drink_formset,
    })

我在我的forms.py中定义了这一点：

class OrderForm(forms.ModelForm):
    class Meta:
        model = Order
        fields = ['description_text', ]


class DrinkForm(forms.ModelForm):
    class Meta:
        model = Drink
        fields = ['type_of_drink']

    DrinkFormSet = inlineformset_factory(
        Order,
        Drink,
        form=DrinkForm,
        can_delete=False,
        extra=10)

这是my models.py：

class Order(models.Model):
    description_text = models.CharField(max_length=200)
    date = models.DateTimeField('date made')
    user = models.ForeignKey(User, null=True, blank=True, )

    def __str__(self):
        return self.description_text

    def was_recent(self):
        return self.date >= timezone.now() - datetime.timedelta(days=1)

    was_recent.admin_order_field = 'date'
    was_recent.boolean = True
    was_recent.short_description = 'Recent?'


class Drink(models.Model):
    order = models.ForeignKey(Order,)
    type_of_drink = models.CharField(max_length=200)
    placed = models.BooleanField(default=False)
    paid = models.BooleanField(default=False)

    def __str__(self):
        return self.type_of_drink
