django-celery

问题 I have a django project that used django-nose. I'd like to add django-celery to the project. I use unit tests. Both django-nose and django-celery need a TEST_RUNNER setting in my settings.py file. Specifically: TEST_RUNNER = 'django_nose.NoseTestSuiteRunner' for django-nose and: TEST_RUNNER = 'djcelery.contrib.test_runner.CeleryTestSuiteRunner' for django-celery. How should I handle this so that I can use both packages? 回答1: I found that the best way to handle this is to skip the Celery test

问题 I am working on a Django project which I have pushed on Heroku , for background tasking I have used Celery . Although Celery works fine locally, but on the Heroku server I have observed that celery worker is getting crashed. I have set CLOUDAMQP_URL properly in settings.py and configured worker configuration in Procfile , but still worker is getting crashed. Procfile web: gunicorn my_django_app.wsgi --log-file - worker: python manage.py celery worker --loglevel=info Settings.py ... # Celery

问题 My task goes into celery and gets results. I know this because I can do this. >>> ts = TaskState.objects.all()[0] >>> ts Out[31]: <TaskState: SUCCESS apps.checklist.tasks.bulk_checklist_process(ec01461b-3431-478d-adfc-6d6cf162e9ad) ts:2012-07-20 14:35:41> >>> ts.state Out[32]: u'SUCCESS' >>> ts.result Out[33]: u'{\'info\': ["Great",]}' But when I attempt to use the documented way to get the result - all hell breaks loose.. >>> from celery.result import BaseAsyncResult >>> result =

问题 In my Django project I'm running some asynchronous tasks using Celery (docs), Django-Celery and RabbitMQ as the broker. Whereas it works in general, I have two problems with my setup: a) the task execution seems to be joined with my request thread. Thus the user http request seems to wait until the task has been executed b) the task execution seems to ignore the countdown flag For testing purposes I have setup a simple TestTask: from celery.task import Task from celery.registry import tasks

问题 I'd like to quit a celery task gracefully (i.e. not by calling revoke(celery_task_id, terminate=True) ). I thought I'd send a message to the task that sets a flag, so that the task function can return. What's the best way to communicate with a task? 回答1: Use signals for this. Celery's revoke is the right choice; it uses SIGTERM by default, but you can specify another using the signal argument, if you prefer. Just set a signal handler for it in your task (using the signal module) that

问题 I have the following setup with a fresh installed celery and django 1.4: settings.py: import djcelery djcelery.setup_loader() BROKER_HOST = 'localhost' BROKER_PORT = 5672 BROKER_USER = 'user' BROKER_PASSWORD = 'password' BROKER_VHOST = 'test' [...] INSTALLED_APPS = [ 'django.contrib.auth', 'django.contrib.admin', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.sites', 'django.contrib.staticfiles', 'djcelery', 'south', 'compressor', 'testapp', ] testapp/tasks.py: from

问题 I am using django-celery for my django project. Last day I have changed my computer's hostname (I am using Ubuntu 12.04, edited file '/etc/hostname'), and after next restart django-celery was failing with error Consumer: Connection Error: [Errno 111] Connection refused. Trying again in 4 seconds... After some research on this error I could find that, changing my host name caused this error from here. My rabbitmq startup log shows file: /var/log/rabbitmq/startup_log Activating RabbitMQ plugins

问题 I have the following code: @task() def handle_upload(title, temp_file, user_id): . . . photo.save() #if i insert here "photo2 = Photo.objects.get(pk=photo.pk)" it works, including the view function return photo.pk #view function def upload_status(request): task_id = request.POST['task_id'] async_result = AsyncResult(task_id) photo_id = async_result.get() if async_result.successful(): photo = Photo.objects.get(pk=photo_id) I use an ajax request to check for the uploaded file but after the

问题 I used pip install django-celery and pip3 install django-celery in Pycharm. After that I use import djcelery ,but Pycharm reminds me no module named djcelery . Then I used pip list I can see django-celery 3.2.2 in the list. But when I went to virtual environment path myenv/lib/site-packages where I can see all the module or app that I have installed such as django-pure-pagination.But I can't find django-celery there. Any friend has any idea, how to fix it? 回答1: Seems like you've installed

问题 backgroud The system is Centos7, which have a python2.x. 1GB memory and single core. I install python3.x , I can code python3 into python3. The django-celery project is based on a virtualenv python3.x,and I had make it well at nginx,uwsgi,mariadb. At least,I think so for no error happend. I try to use supervisor to control the django-celery's worker,like below: command=env/bin/python project/manage.py celeryd -l INFO -n worker_%(process_num)s numprocs=4 process_name=projects_worker_%(process
