        return self.state in self.backend.READY_STATES
      File "/usr/local/lib/python2.6/dist-packages/celery/result.py", line 277, in state
        return self.backend.get_status(self.id)
      File "/usr/local/lib/python2.6/dist-packages/celery/backends/base.py", line 487, in _is_disabled
        raise NotImplementedError('No result backend configured.  '
    NotImplementedError: No result backend configured.  Please see the documentation for more information.

我如何配置后端，以便我可以修复特定的延迟时间

Answer 1

如果使用celeryconfig.py配置模块，可以通过CELERY_RESULT_BACKEND设置配置结果后端

CELERY_RESULT_BACKEND="amqp"

或通过Celery实例

celery = Celery('tasks', backend='amqp', broker='amqp://')

请查看docs了解详情。
