Django SplitDateTime 小部件抛出“list”对象没有属性“strip”

Question

我正在尝试使用 django 创建具有开始日期时间和结束日期时间的事件。在表单中，我尝试使用 AdminSPlitDateTime 小部件分隔日期和时间输入（我想输入一些 JS。）当我尝试创建事件时，django 给了我“'list' object has no attribute'剥离'”错误。 SplitDateTimeWidget 也会发生。

当我删除小部件或使用 DateTimeInput 小部件（没有拆分）时，一切都按预期工作。但是用户可能会混淆输入日期时间的正确格式。所以我想使用 AdminSplitDateTime。

一定是用小部件分割日期和时间，但我想不出办法解决这个问题。

使用 Python 3.7 django 2.2.7 pipenv 2018.11.26

我的模特是

class Event(models.Model):
    event_start = models.DateTimeField()
    event_end = models.DateTimeField()
    notes = models.CharField(max_length=140, null=True, blank=True)
    hasta = models.ForeignKey(Hasta, on_delete=models.CASCADE)
    doktor = models.ForeignKey(User, on_delete=models.CASCADE)



    def __str__(self):
        return f'{self.event_start} -- {self.event_end}'

    class Meta:
        ordering = ['event_start'] 

我的表单类是：

class EventCreateForm(ModelForm):
    event_start = forms.DateTimeField(widget= admin_widgets.AdminSplitDateTime())
    event_end = forms.DateTimeField(widget=admin_widgets.AdminSplitDateTime())

    def __init__(self, *args, **kwargs):
        """this whole thing is for filtering the hasta objects. User can only create an event with his patients."""
        self.user = kwargs.pop('user')
        super().__init__(*args, **kwargs)
        self.fields['hasta'].queryset = Hasta.objects.filter(doktor_id=self.user.id)

    class Meta:
        model = Event
        fields = [
            'event_start',
            'event_end',
            'notes',
            'hasta',
        ]
        labels = {
            'event_start': _('Randevu Başlangıç Tarihi'),
            'event_end': _('Randevu Bitiş Tarihi'),
            'notes': _('Notlar')

        } 

我的视图类是：

class EventCreateView(LoginRequiredMixin, CreateView):
    model = Event
    template_name = 'create_event.html'
    form_class = EventCreateForm
    success_url = '/randevu'

    def get_form_kwargs(self):
        """This adds the user object to the kwargs and it will be used in create event form to filter
        the patients of the current user"""
        kwargs = super(EventCreateView, self).get_form_kwargs()
        kwargs.update({'user': self.request.user})
        return kwargs

    def form_valid(self, form):
        """This adds the current user id to the created event"""
        form.instance.doktor = self.request.user
        form.save()
        messages.success(self.request, f"randevu Kaydedildi!")
        return super().form_valid(form)

我收到以下错误；

您必须将SplitDateTimeField 与AdminSplitDateTime 一起使用。
