python - Celerycam 错误 - 此代码不在事务管理之下

Question

我的设置包括 django 1.5.1、celery 3.1.0 和 redis 作为后端

$ python manage.py celerycam -b 'redis://localhost:6379/0'

使 celerycam 运行，但它不断吐出以下内容:

TransactionManagementError: This code isn't under transaction management

您是否遵循了 django/celery 集成的新指南？ http://docs.celeryproject.org/en/master/django/first-steps-with-django.html

我将我的项目转换为不再调用 djcelery.setup_loader() ，而是现在在 {project}/{project}/celery.py 下有一个 celery.py

另外，您的 CELERY_RESULT_BACKEND 设置为多少？我将我的设置为 djcelery.backends.database:DatabaseBackend

你的大时钟漂移可能与此有关吗？您是否尝试过同步时钟？

我正在使用 celerycam 运行 django 1.6.1，没有任何问题。
