This repo contains my modification of the Celery Database Scheduler from djcelery project. I've used it in production for over a year now without problems.

You'll have to include the scheduler module in your project and modify the models to work with your SQLAlchemy setup. The code in repo just uses temporary in-memory SQLite database since I cannot assume anything.

Finally, set CELERYBEAT_SCHEDULER to yourproject.sqlalchemy_scheduler:DatabaseScheduler.

Adding and removing tasks is done with manipulating the SQLAlchemy models.

dse = model.DatabaseSchedulerEntry()
dse.name = 'Simple add task'
dse.task = 'yourproject.tasks.add'
dse.arguments = '[]'  # json string
dse.keyword_arguments = '{}'  # json string

# crontab defaults to run every minute
dse.crontab = model.CrontabSchedule()

dbsession.add(dse)
dbsession.commit()
