Django 在ModelForm字段中使用self

我有一个Formview并将pk传递给ModelForm。在ModelForm中，我无法在为字段定义的查询集中使用self.pk：

视图.py

class DetailProductForm(forms.ModelForm):


    def __init__(self, *args, **kwargs):
        # get the pk from the FormView at set it as self.pk
        self.pk = kwargs.pop('pk', None)
        super(DetailProductForm, self).__init__(*args, **kwargs)

    # use self.pk in my queryset (there are more fields who use self.pk, this is just one as an example)
    field = forms.ModelChoiceField(queryset=Configuration.objects.filter(product__pk=self.pk), widget=forms.RadioSelect)


    class Meta:
        model = Configuration
        fields = ['field']

[……]

forms.py

class DetailProductForm(forms.ModelForm):


    def __init__(self, *args, **kwargs):
        # get the pk from the FormView at set it as self.pk
        self.pk = kwargs.pop('pk', None)
        super(DetailProductForm, self).__init__(*args, **kwargs)

    # use self.pk in my queryset (there are more fields who use self.pk, this is just one as an example)
    field = forms.ModelChoiceField(queryset=Configuration.objects.filter(product__pk=self.pk), widget=forms.RadioSelect)


    class Meta:
        model = Configuration
        fields = ['field']

NameError:未定义名称“self”

如何将self.pk用于字段？

找到了解决方案。实际上，我甚至不再需要模型了

class DetailProductForm(forms.Form):

    field = forms.ModelChoiceField(queryset=None, widget=forms.RadioSelect)

    def __init__(self, *args, **kwargs):
        self.pk = kwargs.pop('pk', None)
        super().__init__(*args, **kwargs)
        self.fields['field'].queryset = Configuration.objects.filter(product__pk=self.pk))
