如何更改ModelForm中所有Django日期字段的默认小部件？

from django import forms
from django.forms import ModelForm
from .models import YourModel

class CustomModelForm(ModelForm):
    def __init__(self, *args, **kwargs):
        super(CustomModelForm, self).__init__(*args, **kwargs)
        for field_name, field in self.fields.items():
            if isinstance(field.widget, forms.DateInput):
                self.fields[field_name].widget = forms.DateInput(attrs={'type': 'date'})

class YourModelForm(CustomModelForm):
    class Meta:
        model = YourModel
        fields = '__all__'
