Celery Received unregistered task of type (run example)

Question

I\'m trying to run example from Celery documentation.

I run: celeryd --loglevel=INFO

/usr/local/lib/python2.7/dist-packages/celery/loade         


        

Answer 1

I also had the same problem; I added

CELERY_IMPORTS=("mytasks")

in my celeryconfig.py file to solve it.

Answer 2

app = Celery('proj',
             broker='amqp://',
             backend='amqp://',
             include=['proj.tasks'])

please include=['proj.tasks'] You need go to the top dir, then exec this

celery -A app.celery_module.celeryapp worker --loglevel=info

not

celery -A celeryapp worker --loglevel=info

in your celeryconfig.py input imports = ("path.ptah.tasks",)

please in other module invoke task!!!!!!!!

Answer 3

I had the issue with PeriodicTask classes in django-celery, while their names showed up fine when starting the celery worker every execution triggered:

KeyError: u'my_app.tasks.run'

My task was a class named 'CleanUp', not just a method called 'run'.

When I checked table 'djcelery_periodictask' I saw outdated entries and deleting them fixed the issue.

Answer 4

Write the correct path to the file tasks

app.conf.beat_schedule = {
'send-task': {
    'task': 'appdir.tasks.testapp',
    'schedule': crontab(minute='*/5'),  
},

}

Answer 5

What worked for me, was to add explicit name to celery task decorator. I changed my task declaration from @app.tasks to @app.tasks(name='module.submodule.task')

Here is an example

# test_task.py
@celery.task
def test_task():
    print("Celery Task  !!!!")

# test_task.py
@celery.task(name='tasks.test.test_task')
def test_task():
    print("Celery Task  !!!!")

Answer 6

If you are using the apps config in installed apps like this:

LOCAL_APPS = [
'apps.myapp.apps.MyAppConfig']

Then in your config app, import the task in ready method like this:

from django.apps import AppConfig

class MyAppConfig(AppConfig):
    name = 'apps.myapp'

    def ready(self):
        try:
            import apps.myapp.signals  # noqa F401
            import apps.myapp.tasks
        except ImportError:
            pass
