为什么在django中运行syncdb时不会创建celery_taskmeta和其他表？ [英] Why are celery_taskmeta and other tables not being created when running a syncdb in django?

问题描述

我正在尝试设置芹菜和django，但是没有创建celery_taskmeta表。

我遵循了许多（Recent）教程，添加了djcelery和djkombu到我的installed_apps。添加了'BROKER_TRANSPORT =djkombu.transport.DatabaseTransport'行到我的设置等。

我可以运行守护进程，它将执行任务，但是它最后吐出这个追溯：

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

所以如何在syncdb中创建这个表？

解决方案

进入完全相同的问题，全新安装。将芹菜和django-芹菜降级到2.2.7并重新运行syncdb解决了它（对于临时的，反正）。

I'm trying to setup celery and django, but the celery_taskmeta table is not being created.

I've followed numerous (Recent) tutorials, added djcelery and djkombu to my installed_apps. added the 'BROKER_TRANSPORT = "djkombu.transport.DatabaseTransport"' line to my settings, etc.

I can run the daemon just fine, and it will execute tasks, but it spits out this traceback at the end:

 DatabaseError: no such table: celery_taskmeta

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

so how the hell do i get this table created during syncdb?

解决方案

Ran into the exact same issue, fresh install. Downgrading celery and django-celery to 2.2.7 and rerunning syncdb solved it (for the interim, anyway).
