Question

我最近开始使用带有django的rabbitmq和芹菜。我正在使用django-celery，django-celery-email和邮局以异步方式发送电子邮件。安装所有这些软件包后，我的settings.py看起来像

INSTALLED_APPS = [
#other apps
'djcelery',
'djcelery_email',
'post_office'
]


# setup celery
import djcelery
djcelery.setup_loader()

# using post office as the default email backend 
EMAIL_BACKEND = 'post_office.EmailBackend'
# using djcelery's email backend as a backend for post office 

POST_OFFICE_BACKEND = 'djcelery_email.backends.CeleryEmailBackend'

POST_OFFICE = {
    'DEFAULT_PRIORITY' : 'now'
}

EMAIL_HOST = 'YOUR_HOST_NAME'
EMAIL_HOST_USER = "YOUR_HOST_USER_NAME"
EMAIL_PORT = 25  # default smtp port
EMAIL_HOST_PASSWORD = "YOUR_HOST_USER_PASSWORD"
EMAIL_USE_TLS = False
DEFAULT_FROM_EMAIL = 'testing@example.com'

当我试图通过命令

运行django-celery时

**python manage.py celeryd**

正在通过以下错误

Traceback (most recent call last):
  File "manage.py", line 22, in <module>
    execute_from_command_line(sys.argv)
  File "/home/ubuntu/edyodavirtual/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 364, in execute_from_command_line

    worker.get_options() +
TypeError: can only concatenate tuple (not "NoneType") to tuple

此处有人帮我解决此问题

Answer 1

即使我面临同样的问题，我也试图通过djcelery包将芹菜与django整合在一起。然后我阅读了许多博客和文档，并在下面得出结论。

“Celery的早期版本需要一个单独的库来处理Django，但是从3.1开始就不再是这样了。现在支持Django”

[芹菜笔记] [1] http://docs.celeryproject.org/en/latest/django/first-steps-with-django.html

没有使用djcelery我直接编写任务并且它有效！

Answer 2

只需在“〜/ anaconda2 / envs / test_django / lib / python3.6 / site-packages / djcelery / management / commands / celery.py”中注释掉这些行，就像这样：

 14     #    options = (CeleryCommand.options +
 15     #           base.get_options() +
 16     #           base.preload_options)

然后它起作用。
