Django CreateView-如何显示类似integer的相关字段（FK）而不是select？

您好（抱歉我的英语不好），我正试图在django模型的FK关系中使用数字输入而不是选择来显示表单，但我做不到

问题是，我需要在输入框中手动填写产品的ID，但django会自动使用所有产品生成select表单

这是我在forms.py中看到的

class PurchaseForm(forms.ModelForm):
    class Meta:
        model = Purchase
        fields = [
            'date',
            'supplier',
            'warehouse',
        ]
        widgets = {
            'date': forms.DateInput(attrs={
                    'type': 'date',
                }),
        }


class PurchaseItemForm(forms.ModelForm):
    class Meta:
        model = PurchaseItem
        fields = [
            'product',
            'quantity',
            'net_purchase_price',
            'sell_price',
        ]

        widgets = {
            'product': forms.NumberInput(),
        }


PurchaseFormSet = inlineformset_factory(
        Purchase,
        PurchaseItem,
        fields='__all__',
        extra = 10,
    )

这是我的看法

class PruchaseCreateView(CreateView):
    template_name = 'purchases/create_purchase.html'
    form_class = PurchaseForm

    def get_context_data(self, **kwargs):
        context = super(PruchaseCreateView, self).get_context_data(**kwargs)
        if self.request.POST:
            context['formset'] = PurchaseFormSet(self.request.POST)
        else:
            context['formset'] = PurchaseFormSet()
        return context

    def form_valid(self, form):
        context = self.get_context_data()
        formset = context['formset']
        if formset.is_valid():
            self.object = form.save()
            formset.instance = self.object
            formset.save()
            return redirect(self.object.get_absolute_url())  
        else:
            return self.render_to_response(self.get_context_data(form=form))

我试着用widget number输入，但什么都没有！！！有什么想法吗？

在调用inlineformset\u factory时，需要包括自定义表单：

PurchaseFormSet = inlineformset_factory(
    Purchase,
    PurchaseItem,
    form=PurchaseItemForm
    fields='__all__',
    extra = 10,
)
