Django-Celery定期任务错误处理

Question

I have a Celery task that takes no argument that runs periodically in the background.

I want to use on_failure to traceback on the error for the particular object it encounters.

Since it doesn't takes any argument I am not able to assign the value to args .

How should I get the object and the error it encounters while the task is getting executed?

Answer 1

I guess this piece of code is working

from celery.task import PeriodicTask
class Task(PeriodicTask):
     run_every = crontab(minute=0, hour=0)
     def run(self, **kwargs):
         # to do
     def on_failure(self, exc, task_id, args, kwargs, einfo):
         print("Failed")
