Question

我想使用嵌入式内联formset，使用django-extra-views进行创建和更新。

我可以毫无问题地实现典型的（非嵌套的）内联formset。这是一个基本的例子。

# forms.py
class ProductForm(forms.ModelForm):
    class Meta:
        model = models.Product

        # for brevity, assume these fields are defined on the `Product` model
        fields = [
            'name',
            'image',
            'price',
        ]


class VariantForm(forms.ModelForm):
    class Meta:
        model = models.Variant

        # for brevity, assume these fields are defined on the `Variant` model
        fields = [
            'price_override',
            'shipping_dimensions',
        ]


class InlineVariant(InlineFormSet):
    model = models.Variant
    form_class = VariantForm
    extra = 1

和

# views.py
class Add(CreateWithInlinesView):
    template_name = "products/add.html"
    model = models.Product
    form_class = forms.ProductForm

    inlines = [
        forms.InlineVariant,
    ]


class Edit(UpdateWithInlinesView):
    template_name = "products/edit.html"
    model = models.Product
    form_class = forms.ProductForm
    context_object_name = "product"

    inlines = [
        forms.InlineVariant,
    ]

但是，现在我希望Stock为每个Variant内联。

# forms.py
class StockForm(forms.ModelForm):
    class Meta:
        model = models.Stock

        # for brevity, assume these fields are defined on the `Stock` model
        fields = [
            'location',
            'quantity',
        ]


class InlineStock(InlineFormSet):
    model = models.Stock
    form_class = StockForm
    extra = 1

如何修改上面定义的视图？

现有的django-extra-views issue断言这是可能的。但是，没有明确的例子说明如何做到这一点。有人建议制作自定义formset_class。

我还找到了一个单独的包django-nested-admin，它定义了一个看似通用的NestedInlineFormset类。可以以某种方式整合吗？

我发现这真令人困惑。
