当我运行pprint(request.POST)时，它只返回表单集最后一个表单的数据。为什么会这样？这是我的代码。
我的models.py：

class Order(models.Model):
    date = models.DateField(unique=True, blank=True, null=True)
    first_course = models.CharField(null=True, blank=True, unique=False, max_length=30)
    first_course_quantity = models.IntegerField()
    second_course = models.CharField(null=True, blank=True, unique=False, max_length=30)
    second_course_quantity = models.IntegerField()
    dessert = models.CharField(null=True, blank=True, unique=False, max_length=30)
    dessert_quantity = models.IntegerField()
    drink = models.CharField(null=True, blank=True, unique=False, max_length=30)
    drink_quantity = models.IntegerField()

    def __str__(self):
        return f"Date of order: {self.date}"

我的forms.py：

class DisabledOptionWidget(forms.Select):
    def render(self, name, value, attrs=None, renderer=None):
        html_code = super(DisabledOptionWidget, self).render(name, value, attrs, renderer)
        html_code = html_code.replace(f'<option value=""', f'<option value="" disabled')
        return html_code

class OrderForm(forms.ModelForm):
    first_course = forms.ChoiceField(choices=[("", 'Select a dish')] + [(f"{item}", item) for item in list(
    Menu.objects.values_list("first_course", flat=True))], widget=DisabledOptionWidget, required=False)
    first_course_quantity = forms.IntegerField(min_value=0)
    second_course = forms.ChoiceField(choices=[("", 'Select a dish')] + [(f"{item}", item) for item in list(
    Menu.objects.values_list("second_course", flat=True))], widget=DisabledOptionWidget, required=False)
    second_course_quantity = forms.IntegerField(min_value=0)
    dessert = forms.ChoiceField(choices=[("", 'Select a dish')] + [(f"{item}", item) for item in list(
    Menu.objects.values_list("dessert", flat=True))], widget=DisabledOptionWidget, required=False)
    dessert_quantity = forms.IntegerField(min_value=0)
    drink = forms.ChoiceField(choices=[("", 'Select a dish')] + [(f"{item}", item) for item in list(
    Menu.objects.values_list("drink", flat=True))], widget=DisabledOptionWidget, required=False)
    drink_quantity = forms.IntegerField(min_value=0)
    date = forms.DateField(required=False)

    class Meta:
        model = Order
        fields = "__all__"

    def save(self, commit=True):
        if commit:
            order = Order.objects.create(
                date=self.cleaned_data['date'],
                first_course=self.cleaned_data['first_course'],
                first_course_quantity=self.cleaned_data['first_course_quantity'],
                second_course=self.cleaned_data['second_course'],
                second_course_quantity=self.cleaned_data['second_course_quantity'],
                dessert=self.cleaned_data['dessert'],
                dessert_quantity=self.cleaned_data['dessert_quantity'],
                drink=self.cleaned_data['drink'],
                drink_quantity=self.cleaned_data['drink_quantity']
            )
            return order

我的**views.py:**

class OrderView(LoginRequiredMixin, CreateView):
    login_url = reverse_lazy('login')
    template_name = "myapp/order.html"
    success_url = reverse_lazy("order_success")
    formset_class = formset_factory(OrderForm, extra=5)

    def get(self, request, *args, **kwargs):
        days = self._get_days()
        formset = self.formset_class()

        return render(request, self.template_name, {
            'formset': formset,
            'Monday': days[0],
            'Tuesday': days[1],
            'Wednesday': days[2],
            'Thursday': days[3],
            'Friday': days[4]
        })

    def post(self, request, *args, **kwargs):
        formset = self.formset_class(request.POST)

        if formset.is_valid():
            formset.save()
            return redirect(self.success_url)
        else:
            pprint(request.POST)
            return redirect('order')

我的模板看起来像：

{% for form in formset.forms %}
        {% if forloop.counter == 1 %}
