Even if I have the following lines in settings.py:
CELERY_ACCEPT_CONTENT = ['application/json'] CELERY_TASKS_SERIALIZER = 'json' CELERY_RESULT_SERIALIZER = 'json' from kombu import serialization serialization.registry._decoders.pop("application/x-python-serialize")
I still get inappropriate trace content. It’s strange that I already have celery working perfectly with exactly the same settings elsewhere. If anyone could offer a solution, that would be very helpful. Django's version is 1.7.1, and celery was downloaded today, so it should be the last. Using rabbitmq as a broker. The following is a complete error trace.

This is what I have in the celery.py file in the project directory, parallel to the settings.py file:
from __future__ import absolute_import import os from celery import Celery from django.conf import settings os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'projectname.settings') app = Celery('projectname',broker='amqp://',backend='amqp://',) app.config_from_object('django.conf:settings') app.autodiscover_tasks(lambda: settings.INSTALLED_APPS) @app.task(bind=True) def debug_task(self): print('Request: {0!r}'.format(self.request))
Please let me know if more information is needed.
