类型对象 'Event' 没有属性“_default_manager”

Question

我收到以下错误：

AttributeError at /admin2/event/edit/1/ type object 'Event' has no attribute '_default_manager'

来自新添加的代码：

(views.py)

@method_decorator(staff_member_required, name='dispatch')
class EditEvent(LoginRequiredMixin, UpdateView):
    template_name = 'admin2/events/edit-event.html'
    form_class = AddEventForm
    model = Event
    slug_url_kwarg = "events_id"
    slug_field = 'id'
    success_url = '/admin2/event/'

(urls.py)

url(r'^admin2/event/edit/(?:(?P<events_id>.+)/)?$', login_required(EditEvent.as_view()), name='edit-event-view'),

(models.py)

class Event(models.Model):
    title = models.CharField(help_text='Name of the event', max_length=250, null=False, blank=False)
    location = models.CharField(help_text='Location of the event', max_length=250, null=False, blank=False)
    date = models.DateTimeField(auto_now=False)

(forms.py)

class AddEventForm(forms.ModelForm):
    class Meta:
        model = Event
        fields = ('title', 'location', 'date')

我正在使用 Django 1.11（已过时但无法更新）

已解决：

我将我的视图重命名为 EditIndiView 并将我的模型重命名为 IndiView，但是，我没有任何冲突的名称...无论如何，重命名模型和视图解决了错误。
