python-xlib VS django-celery-beat

The last error message claims Xlib.ext.shape has no attribute SO even though it totally should. What's your version of python-xlib (pip show python-xlib or use your package manager)? On my working ueberzug setup it's 0.31. Maybe also check/usr/lib/python3.10/site-packages/Xlib/ext/shape.py and make sure the SO class is in there. Not a solution, but maybe somewhere to start looking.

If you're using X11, you could look into xlib. But the documentation for the Pyton Xlib is, using its own words, "not finished by far".

I was looking for a nice way to manipulate periodic tasks in Celery. I found an amazing django-celery-beat package that provides PeriodicTask database objects. With PeriodicTask objects, you can dynamically add/remove/update periodic tasks in Celery. I want to share my approach. I've created an example GitHub repository and wrote step-by-step article.

Please take a look at https://github.com/celery/django-celery-beat with this package you can dynamically define periodic tasks. They are stored in your database, so they are persistent between deployments. I'm using this package with Celery in my project for server uptime monitoring, it is working well. I can dynamically add/delete/update any task.

Something similar is presented in django-celery-beat where you’re able to create schedule for running repeated task. So, there is choice field in admin, and choices are literally names of registered celery tasks.

I would recommend using celery in combination with celery beat scheduling and this package https://github.com/celery/django-celery-beat . What this means is if you have a task that you want to dynamically schedule for different times for different users all you have to do as add a new row to a database table and celery will handle the rest for executing.

If you want more control and/or visibility into your periodic tasks, I'd go with something like Celery Beat, that's easily integrated with Django: https://github.com/celery/django-celery-beat

For me it was django-celery-beat

I use a Django extension called django-celery-beat. It creates several models & one of those models is called crontab. It has a few fields & I would like to add one more field so that I can name these crontabs for easy reference. So I need to override the model & add the field.
