无法获得实时信息的芹菜任务

Question

我想获取芹菜信息的任务，然后参考文档[http://docs.celeryproject.org/en/latest/userguide/workers.html?highlight=revoke#inspecting-workers）这是代码。

celery.py

app = Celery('tasks', broker='redis://127.0.0.1:6379/0')

app.config_from_object('django.conf:settings')
app.autodiscover_tasks(lambda: settings.INSTALLED_APPS)

i = app.control.inspect()

views.py

from myproject.celery import i
class AAA(APIView):
    def get(self,request):
        print(i.registered())
        print(i.active())
        print(i.scheduled())
        print(i.reserved())
    return Response("ok")

这是打印结果

{'celery@wwl': ['quantum.tasks.pro_execute']}
{'celery@wwl': []}
{'celery@wwl': []}
{'celery@wwl': []}

task.py

@task
def pro_execute(code, oper_id, number_of_shots):
   operation = Operation.objects.filter(id=oper_id, status=0).first()
   if not operation:
        return
    operation.start_date = datetime.now()
    operation.status = 1
    operation.save()
    try:
        qc = QuantumCircuit.from_qasm_str(code)
        backend = Aer.get_backend('qasm_simulator')
        job_sim = execute(qc, backend, shots=number_of_shots)
        sim_result = job_sim.result()
        ope_result = sim_result.get_counts(qc)
        operation.result = ope_result
        operation.end_date = datetime.now()
        operation.status = 2
    except Exception as e:
        logging.error("execute program failed：error %s" % str(e))
        operation.result = str(e)
        operation.status = 3
    operation.save()

无法获得最后三个结果？我不知道为什么但是可以在鲜花仪表板上看到它们非常感谢。
