如何在django视图中使用芹菜存储延迟呼叫的结果？ [英] How to store the result of a delay-call using celery in a django view?

问题描述

我遵循 http ：//celeryq.org/docs/django-celery/getting-started/first-steps-with-django.html ，并创建了一个在tasks.py中调用我的测试方法的视图：

I`ve followed the guidelines in http://celeryq.org/docs/django-celery/getting-started/first-steps-with-django.html and created a view that calls my test method in tasks.py:

import time
from celery.decorators import task

@task()
def add(x, y):
    time.sleep(10)
    return x + y

但是如果我的add-method需要很长时间的响应，那么如何在调用add.delay（1,2）时存储结果对象，并使用它来检查进度/成功/结果？ / p>

But if my add-method takes a long time to respond, how can I store the result-object I got when calling add.delay(1,2) and use it to check the progress/success/result using get later?

推荐答案

您只需要task-id：

You only need the task-id:

result = add.delay(2, 2)
result.task_id

使用这个你可以轮询任务的状态（使用例如AJAX）
Django-celery附带了一个返回结果和JSON的状态的视图：
http://celeryq.org/docs/django-celery /reference/djcelery.views.html

With this you can poll the status of the task (using e.g. AJAX) Django-celery comes with a view that returns results and status in JSON: http://celeryq.org/docs/django-celery/reference/djcelery.views.html
