我正在尝试设置celery和django,但是没有创建celery_taskmeta表。
我已经按照了很多(最近的)教程,将djcelery和djkombu添加到了我的installed_apps。将'BROKER_TRANSPORT =“djkombu.transport.DatabaseTransport”'行添加到我的设置等。
我可以正常运行守护进程,并且它将执行任务,但它会在最后吐出这个回溯:

DatabaseError: no such table: celery_taskmeta
- ============================
那么我怎么能在syncdb中创建这个表?
答案 0 :(得分:17)
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
之前我遇到过同样的问题,但是修好了。
答案 1 :(得分:10)
我也遇到了以下错误:
DatabaseError: no such table: djkombu_queue
在进一步研究之后,我相信解决此问题的正确方法(从here拉出来)将其添加到INSTALLED_APPS
:
INSTALLED_APPS = ('djcelery.transport', )
添加kombu.transport.django
感觉不正确。
答案 2 :(得分:5)
进入完全相同的问题,全新安装。将celery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)。
答案 3 :(得分:5)
我遇到了类似的错误:
DatabaseError: no such table: djkombu_queue
就我而言,我需要将相关技术的Django应用添加到INSTALLED_APPS
设置中。就我而言,它是:kombu.transport.django
之后,我重新syncdb
,一切正常。在你的情况下,也许可以在芹菜鸡蛋中加入一些东西。
答案 4 :(得分:1)
我在运行manage.py dumpdata
时遇到此错误。我尝试了两个不同的2.2.x版本的 celery 和 django-celery 包与MySQL数据库。在我的情况下升级到2.2.7没有解决问题。在这个Github Issue #34上发现的建议是什么。
在Django 1.3+上使用dumpdata时,添加--exclude djcelery
选项。 (当然,如果您只转储应用程序和模型的子集,则无论如何都不会得到丢失的表错误。如果您不首先使用dumpdata,则此答案不适用。)
答案 5 :(得分:0)
问题可能是SQLite3。你不能在Django中同时使用它,它会引发一个误导性的错误。切换到PostgreSQL或MySQL,尤其是芹菜开发。
或者,咬紧牙关,然后设置RabbitMQ ......
