Celery-Django: Unable to execute tasks asynchronously

I'm trying to run some tasks in the background while users browse my site, but whenever I call a function using Celery it seems to be executed synchronously instead of asynchronously.

e.g., when I call function.delay() the entire site hangs until function.delay() returns. Other methods of calling functions in a similar manner (apply_async, subtasks) exhibit the same problem.

I'm guessing something in either Django or Celery is misconfigured, but I don't know what it is.

Celery configuration in settings.py:

import djcelery
djcelery.setup_loader()

CELERY_RESULT_BACKEND = "amqp"
CELERYBEAT_SCHEDULER = "djcelery.schedulers.DatabaseScheduler"
BROKER_HOST = "localhost"
BROKER_PORT = 5672
BROKER_USER = "test"
BROKER_PASSWORD = "test"
BROKER_VHOST = "testhost"

TEST_RUNNER = "djcelery.contrib.test_runner.run_tests"

CELERY_IMPORTS = ("myapp.tasks",)

BROKER_BACKEND = "memory"
CELERY_ALWAYS_EAGER = True

Trying to start the Celery daemon wi开发者_开发技巧th "./manage.py celeryd", I get the following output:

Try removing

CELERY_ALWAYS_EAGER = True

You are explicitly asking celery to execute tasks synchronously. It'll always wait for the result. This setting is useful for writing unit tests etc.
