U＆＃39; __模块__＆＃39;创建内联formset时出错

Question

我是Django的新手。我正在尝试使用inlineformset_factory包含多个模型表单，但我收到以下错误：

Exception Type: KeyError at /dataentry/dataentry
Exception Value: u'__module__'

这是我的formset和模型表单：

ProductFormSet = inlineformset_factory(Product, Size , 
    ProductImage, 
    can_delete=False, fields=('image',) , extra=1)


class ProductModelForm(forms.ModelForm):
    class Meta:
        model = Product
        exclude = ['is_verified' , 'in_stock']

这是完整的追溯

为什么会发生错误，我该怎么做才能解决？

Answer 1

ProductFormSet = inlineformset_factory(Product, Size, ProductImage, ...)

inlineformset_factory的第三个参数应该是模型表单类。从名称ProductImage，听起来你已经通过了一个模型。也许您打算使用ProductModelForm代替。
