EDIT 1:
Actually, print
statements outputs to the Celery terminal, instead of the terminal where the python program is ran - as @PatrickAllen indicated
OP
I've recently started to use Celery, but can't even get a simple test going where I print a line to the terminal after a 30 second wait.
In my tasks.py
:
from celery import Celery
celery = Celery(__name__, broker='amqp://guest@localhost//', backend='amqp://guest@localhost//')
@celery.task
def test_message():
print ("schedule task says hello")
in the main module for my package, I have:
import tasks.py
if __name__ == '__main__':
<do something>
tasks.test_message.apply_async(countdown=30)
I run it from terminal:
celery -A tasks worker --loglevel=info
Task is ran correctly, but nothing on the terminal of the main program. Celery output:
[2016-03-06 17:49:46,890: INFO/MainProcess] Received task: tasks.test_message[4282fa1a-8b2f-4fa2-82be-d8f90288b6e2] eta:[2016-03-06 06:50:16.785896+00:00]
