类型错误：modelform_factory() 'extra' 遇到意外的关键字参数

我正在尝试使用modelformset_factory来呈现多个表单。但是，当尝试运行服务器时，会出现TypeError: modelform_factory() got an unexpected keyword argument 'extra'错误

所有在线消息来源都说我应该能够在modelform_factory中指定extra参数，但我似乎不能。

forms.py

class MapSeniorTeachForm(ModelForm):
role = forms.CharField(max_length=32)
def __init__(self, teach_id, *args, **kwargs):
super(MapSeniorTeachForm, self).__init__(*args, **kwargs)
self.teach_id = teach_id
self.fields['senior'] = forms.ChoiceField(choices=[(1,1),(2,2),(3,3)])

class Meta:
model = MapSeniorTeach
fields = ['role', 'senior']
MapSeniorTeachFormset = modelform_factory(MapSeniorTeach, form=MapSeniorTeachForm, extra=1)

剪切输出日志

MapSeniorTeachFormset = modelform_factory(MapSeniorTeach, form=MapSeniorTeachForm, extra=1)

需要注意的一点是，如果我删除了额外的关键字，那么表单的一个实例就会成功呈现。

以下是我之前谈到的一些来源：

非常感谢您的帮助！
