Python TypeError:uuu init_uuuuuuuuuuu（）为关键字参数'；获取了多个值；选择'；

回溯如下

class StatisticsBaseForm(forms.Form):
    type_choice = forms.ChoiceField(_("Type"), choices=settings.STATISTICS_TYPE_CHOICES, default=0)
    period = forms.ChoiceField("Period", max_length=20, choices=settings.PERIODS, default='week')

    def __init__(self, *args, **kwargs):
        super(StatisticsBaseForm, self).__init__(*args, **kwargs)
        self.helper = FormHelper(self)

    class Meta:
        model = Statistics
        fields = '__all__'

TypeError:\uuuu init\uuuuuu（）为关键字参数“choices”获取了多个值

我有这个错误，但我没有设法纠正它。我怎样才能继续处理这个错误呢？起初，

StatisticsBaseForm

是一个

forms.ModelForm

，

type\u选项

和

period

在我的统计模型中，两者都是

SmallIntegerfield

。在这一特定背景下，一切都很顺利

更改为

type_choice = forms.ChoiceField(label=_("Type"), choices=settings.STATISTICS_TYPE_CHOICES, initial=0)
period = forms.ChoiceField(label="Period", choices=settings.PERIODS, initial='week')
