为什么在django中运行syncdb时没有创建celery_taskmeta和其他表？

Question

我正在尝试设置celery和django,但是没有创建celery_taskmeta表.

我遵循了许多(最近的)教程,将djcelery和djkombu添加到我的installed_apps.将'BROKER_TRANSPORT ="djkombu.transport.DatabaseTransport"'行添加到我的设置等.

我可以很好地运行守护进程,它将执行任务,但它会在最后吐出这个回溯:

- ============================

那么我怎么能在syncdb中创建这个表呢？

Answer 1

这里的问题实际上是南方管理djcelery表.您需要将djcelery迁移到它的新架构.如果您从早期版本升级了djcelery并且已经安装了一组表,则需要先进行虚假迁移:

python manage.py migrate djcelery 0001 --fake
python manage.py migrate djcelery

我以前遇到过同样的问题,但是修好了.

Answer 2

我也收到以下错误:

DatabaseError: no such table: djkombu_queue

在进一步研究之后,我相信解决这个问题的正确方法(从这里拉出来)它将以下内容添加到INSTALLED_APPS:

INSTALLED_APPS = ('djcelery.transport', )

添加kombu.transport.django感觉不正确.

Answer 3

进入完全相同的问题,全新安装.将芹菜和django-celery降级到2.2.7并重新运行syncdb解决了它(无论如何都是临时的).

Answer 4

我收到了类似的错误:

DatabaseError: no such table: djkombu_queue

就我而言,我需要将相关技术的Django应用程序添加到INSTALLED_APPS设置中.就我而言,它是:kombu.transport.django

在那之后,我重新开始syncdb,一切正常.在您的情况下,也许可以在芹菜蛋中添加一些东西到路径中.
