带有ModelBase的Django Formsets不会默认呈现复选框而是一个下拉列表

from django import forms
from django.forms import formset_factory
from django.forms.models import BaseModelFormSet

class CustomBooleanField(forms.TypedChoiceField):
    def __init__(self, *args, **kwargs):
        kwargs['coerce'] = lambda x: bool(int(x))
        kwargs['choices'] = ((1, 'True'), (0, 'False'))
        super().__init__(*args, **kwargs)

class MyForm(forms.ModelForm):
    my_boolean_field = CustomBooleanField()

    class Meta:
        model = MyModel
        fields = '__all__'

MyFormSet = formset_factory(MyForm, formset=BaseModelFormSet)
