如何从celery任务中返回django视图？

Question

我需要从django celery任务内部返回表单。我的任务从下面的django视图中调用：

class MyView(CreateView):
    model = MyModel
    form_class = MyForm
    success_url = '/create/form'

    def form_valid(self, form):
        form.save()
        # I call my task in here
        period.delay()
        print("Loading task...")

        return super(MyView, self).form_valid(form)

我的任务的名称是“ period”，当我的[[IF中的条件为true时，它将日期与打开事件的目标进行比较。我的“ event”是用户必须确认在场的处方。

我的任务：

from .views import MyAnotherView 
# others imports...

"""
    in my settings.py, I had to call tha task every minute:
    CELERYBEAT_SCHEDULE = {
    'add-periodic-events': {
        'task': 'myapp.tasks.period',
        'schedule': crontab(minute='*'),
        }
    }
"""

@shared_task(serializer='json')
def period():
    event = MyModel.objects.get(id=1) # I limited my model to receive only one object

    request = RequestFactory.get('/another/form') 
    view = MyAnotherView() 

    week_d = week_day(event.day) # day is a field of my model
    event_d = event_day(week_d, event.hour) # hour is a field of my model
    conf_d = presence_confirm(event.before_days, event.begin_hour, event_d) # before_days and begin_hour are fields of my model

    utc_now = pytz.utc.localize(datetime.utcnow())
    n = utc_now.astimezone(pytz.timezone('America/Recife'))
    t_str = '{}-{}-{}'.format(n.year, n.month, n.day)
    t_hour = ' {}:{}'.format(n.hour, n.minute)

    today = t_str + t_hour
    today = datetime.strptime(today, '%Y-%m-%d %H:%M')

    if (today >= conf_d) and (today < event_d):
        # HOW TO CALL MY FORMULARY???
        print("Call my formulary")
        view.setup(request)

    else:
        # another thing

我想在调用任务后并且条件为真时显示的公式将来自django模型，如下所示：
class MyAnotherModel(models.Model):
    OPTIONS = (
        (True, 'Sim'),
        (False, 'Não'),
    )

    player = models.OneToOneField(MyUserModel, primary_key=True, on_delete=models.CASCADE)
    confirm = models.BooleanField(choices=OPTIONS, default=False)
    modified = models.DateTimeField(auto_now_add=True)

简而言之，我希望我的处方在我的情况为真时出现。因此，我尝试将RequestFactory.get用于任务，以捕获URL并调用视图（MyAnotherView）。 
     # ...
     request = RequestFactory.get('/another/form') 
     view = MyAnotherView() # View responsável em instanciar MyAnotherModel 
     # ...
     if (today >= conf_d) and (today < event_d):
        view.setup(request)

但是，我收到了
ImportError：无法导入名称'MyAnotherView'] >>。如果有人可以帮助我，我非常感谢！

我的问题是检查今天的日期是否在两个日期之间。如果是这样，我必须“显示”表格。我用芹菜做的这张支票。我的问题是，只要今天的日期在启用表格的日期之间，我该怎么做。我解决了如下问题：
