【问题描述】：

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，但它不断发出以下错误：

TransactionManagementError: This code isn't under transaction management

【问题讨论】：

我在 Django 1.4.8 中遇到了同样的问题。你找到解决方案了吗？我的直觉是，这可能是由于 Django 交易，众所周知，这些交易不是 100% 可靠的。据说它在 Django 1.6 上要好得多，这让我认为最新的 kombu/celery 仅针对此设置进行了测试？
嗯，很奇怪。我将尝试升级到 Django 1.6，看看它是否有效。

【解决方案1】：

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

还有你的 CELERY_RESULT_BACKEND 设置是什么？我的设置为 djcelery.backends.database:DatabaseBackend

你的大时钟漂移可能与它有关吗？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。
