python - 模块的对象没有属性 'SelectDateWidget'

Question

我正在尝试在 Calendarium 中创建自定义表单/ View ，但我一直收到错误

AttributeError: 'module' object has no attribute 'SelectDateWidget'

在我的 forms.py 中创建事件

class CreateEvent(forms.ModelForm):
    class Meta:
        model = Event
        fields = ['title', 'start', 'end', 'description', 'category', 'created_by', 'rule', 'end_recurring_period']
        widgets = {
            'start': forms.SelectDateWidget()
        }

views.py 中的 EventCreateView

class EventCreateView(EventMixin, CreateView):
    form_class = CreateEvent
    model = Event

有谁知道我为什么会收到这个错误

额外(如果允许):

在 EventCreateView 中，它被传递“EventMixin”，看起来像这样

class EventMixin(object):
    """Mixin to handle event-related functions."""
    model = Event
    fields = '__all__'



    @method_decorator(permission_required('calendarium.add_event'))
    def dispatch(self, request, *args, **kwargs):
        return super(EventMixin, self).dispatch(request, *args, **kwargs)

有人能给我解释一下吗？

您缺少小部件:

class CreateEvent(forms.ModelForm):
    class Meta:
        model = Event
        fields = ['title', 'start', 'end', 'description', 'category', 'created_by', 'rule', 'end_recurring_period']
        widgets = {
            'start': forms.widgets.SelectDateWidget()
        }
        #                    ^^

另一方面，我怀疑包含该片段的文件名为 forms.py
