Django异步任务之Celery的基本使用

pip install django-celery
pip install celery

import djcelery

djcelery.setup_loader() 
BROKER_URL = 'django://'

INSTALLED_APP = (
 ...
 'app'
 'djcelery',
 'kombu.transport.django',
)

# 相对路径导入, 防止导入 celery 时冲突
from __future__ import absolute_import
import os
from celery import Celery
from django.conf import settings

# 让 celery 能找到 django 项目
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'project.settings')
# 创建一个 celery 应用
app = Celery('project')

# 导入配置
app.config_from_object('django.conf:settings')
# 自动发现 task
app.autodiscover_tasks(lambda: settings.INSTALLED_APPS)

@app.task(bind=True)
def debug_task(self):

 print('Request: {0!r}'.format(self.request))

from __future__ import absolute_import

# This will make sure the app is always imported when
# Django starts so that shared_task will use this app.
from .celery import app as celery_app

from celery.task import task
from time import sleep

@task()
def helloWorld():
 print 'helloWorld'
 sleep(10)
 print 'helloWorld'
 return 'helloCelery'

from tasks.py import helloWorld

def home():

 helloWorld.delay()

 return HttpResponse('helloCelery')

python manage.py migrate
