![]() Import must be protected with if _name_ = '_main_'. When running the worker programmatically with the scheduler, you must keep in mind that the Up by other workers with the scheduling component enabled. This way, if a worker with active scheduler dies, the scheduling work will be picked If they don’t, one of the idle schedulers will start Idle schedulers will periodically (every 15 minutes) check whether the queues they’re Workers with scheduler enabled, only one scheduler will be actively working for a given queue.Īctive schedulers are responsible for enqueueing scheduled jobs. ![]() Only a single scheduler can run for a specific queue at any one time. We then showed how to create a custom Django Admin command and a periodic task with Celery Beat to run that command automatically.From rq import Worker, Queue from redis import Redis redis = Redis () queue = Queue ( connection = redis ) worker = Worker ( queues =, connection = redis ) worker. ![]() In this article we guided you through setting up Docker containers for Celery, Celery Beat, and Redis. In the code, we queried the database for orders with a confirmed_date of today, combined the orders into a single message for the email body, and used Django's built in mail_admins command to send the emails to the admins.Īdd a dummy admin email and set the EMAIL_BACKEND to use the Console backend, so the email is sent to stdout, in the settings file:Ĭelery_1 | Content-Type: text/plain charset = "utf-8"Ĭelery_1 | Content-Transfer-Encoding: 7bitĬelery_1 | Subject: Order Report for to Ĭelery_1 | From: | To: Ĭelery_1 | Order: 3947963f-1860-44d1-9b9a-4648fed04581 - product: CoffeeĬelery_1 | Order: ff449e6e-3dfd-48a8-9d5c-79a145d08253 - product: RiceĬelery_1 | -Ĭelery_1 | Ĭelery_1 | E-mail Report was sent. write ( "E-mail Report was sent." ) else : self. filter ( confirmed_date_range = ( today_start, today_end )) if orders : message = "" for order in orders : message += f " " ) mail_admins ( subject = subject, message = message, html_message = None ) self. combine ( tomorrow, time ())) class Command ( BaseCommand ): help = "Send Today's Orders Report to Admins" def handle ( self, * args, ** options ): orders = Order. combine ( today, time ())) today_end = make_aware ( datetime. now () tomorrow = today + timedelta ( 1 ) today_start = make_aware ( datetime. ![]() In the "core" directory, create a celery.py file and add the following code:įrom datetime import timedelta, time, datetime from import mail_admins from import BaseCommand from django.utils import timezone from import make_aware from orders.models import Order today = timezone. project/:/usr/src/app/ environment : - DEBUG=1 - DJANGO_ALLOWED_HOSTS=localhost 127.0.0.1 depends_on : - redisīefore building the new containers we need to configure Celery in our Django app. project command : celery -A core beat -l info volumes :. project/:/usr/src/app/ environment : - DEBUG=1 - DJANGO_ALLOWED_HOSTS=localhost 127.0.0.1 depends_on : - redis celery-beat : build. project command : celery -A core worker -l info volumes :. project/:/usr/src/app/ ports : - 1337:8000 environment : - DEBUG=1 - DJANGO_ALLOWED_HOSTS=localhost 127.0.0.1 depends_on : - redis redis : image : redis:alpine celery : build. project command : python manage.py runserver 0.0.0.0:8000 volumes :. ![]()
