如何在UpdateView中访问SelectDateWidget？

from django.views.generic.edit import UpdateView
from django.forms.widgets import SelectDateWidget

class YourUpdateView(UpdateView):
    model = YourModel
    fields = ['field1', 'field2', ...]
    template_name = 'your_template.html'

<form method="post">
    {% csrf_token %}
    {{ form.field1 }}
    {{ form.field2 }}
    ...
    <input type="submit" value="Save">
</form>

from django import forms

class YourForm(forms.ModelForm):
    field1 = forms.DateField(widget=SelectDateWidget)

    class Meta:
        model = YourModel
        fields = ['field1', 'field2', ...]

from django.urls import path
from .views import YourUpdateView

urlpatterns = [
    path('your_model/<int:pk>/update/', YourUpdateView.as_view(), name='your_update_view'),
    ...
]
