TypeError:\uuuu init\uuuuuuuu（）以Django形式获取了一个意外的关键字参数&；模板集

在下面的Django文档中，我返回了以下内容：

__init__() got an unexpected keyword argument 'choices'


File "/Users/emilepetrone/Envs/kishikoi/lib/python3.6/site-packages/django/utils/functional.py" in __get__

Exception Value: __init__() got an unexpected keyword argument 'choices'

My Form&Formset-我正在使用forms.Form，因为我将使用这些字段更新Form.is\u valid（）中的其他字段

解决方案

对于其他遇到此问题的人，kwargs.pop（'choices'）确实需要位于表单中Super（）的上方。init

---

这解决了错误，但随后在没有将数据加载到ChoiceField的情况下提供了一个表单集。我将该字段更改为ModelChoiceField&set queryset=None（将在初始化中更改），从而解决了问题。

在调用

super

之前弹出：

def __init__(self, *args, **kwargs):

        queryset = kwargs.pop('choices')

        super(SoldTransactionForm, self).__init__(*args, **kwargs)

        self.fields['old_transaction'].queryset = queryset

谢谢Jens，这解决了错误！+1现在“old_transaction”字段中没有queryset数据，但这是另一个问题。再次感谢您的帮助

class SoldTransactionForm(forms.Form):

    old_transaction = forms.ChoiceField()

    num_shares = forms.IntegerField(
        min_value=0
    )

    class Meta:
        fields = [
            'old_transaction',
            'num_shares',
        ]

    def __init__(self, *args, **kwargs):
        super(SoldTransactionForm, self).__init__(*args, **kwargs)
        self.fields['old_transaction'].queryset = kwargs.pop('choices')

SoldFormset = forms.formset_factory(
    SoldTransactionForm,
    formset=forms.BaseFormSet,
    extra=2
)

def __init__(self, *args, **kwargs):

        queryset = kwargs.pop('choices')

        super(SoldTransactionForm, self).__init__(*args, **kwargs)

        self.fields['old_transaction'].queryset = queryset
