   app = Celery('celertest', broker='amqp://guest@localhost//')
    
   # Using a string here means the worker will not have to
   # pickle the object when using Windows.
   app.config_from_object('django.conf:settings')
   app.autodiscover_tasks(lambda: settings.INSTALLED_APPS)
    
   app.conf.update(CELERY_RESULT_BACKEND='djcelery.backends.database.DatabaseBackend')
