How to implement autoretry for Celery tasks

Question

In Celery, you can retry any task in case of exception. You can do it like so:

@task(max_retries=5)
def div(a, b):
    try:
        return a / b
            


        

Answer 1

Celery (since version 4.0) has exactly what you were looking for:

@app.task(autoretry_for=(SomeException,))
def my_task():
    ...
