I am just getting started with celery,trying to run a periodic task.
Configured *rabbitmq** added celeryconfig.py.
And added following code in tasks.py:
from celery.decorators import periodic_task
from datetime import timedelta
@periodic_task(run_every=timedelta(seconds=2))
def every_2_seconds():
print("Running periodic task!")
Now when I start celerybeat by typing "celerybeat" in my terminal it starts to run with follwing message
celerybeat
celerybeat v3.0.3 (Chiastic Slide) is starting.
__ - ... __ - _
Configuration ->
. broker -> amqp://arnold@localhost:5672//
. loader -> celery.loaders.default.Loader
. scheduler -> celery.beat.PersistentScheduler
. db -> celerybeat-schedule
. logfile -> [stderr]@INFO
. maxinterval -> now (0s)
[2012-08-03 14:24:52,202: INFO/MainProcess] Celerybeat: Starting...
And there is no output of every_2_seconds
method in the terminal.I am assuming I have to specify which app to run or wich tasks during the celerybeat command.How to do that?
How can I specify tasks and print the line after every 2 seconds as a periodic tasks?
Thanks.
Add CELERY_IMPORTS=("tasks",)
to your celeryconfig.py then run celerybeat.
