Question

我有以下代码

from utils import SendSMS
from celery.exceptions import *


@celery.task(bind=True, max_retries=3)
def send_sms(self,sms_list):
    failed_items = []
    for sms_item in sms_list:
        status = SendSMS( **sms_item )
        if status in ['Timeout','Error']:
            failed_items.append( sms_item )

    if len(failed_items) > 0:
        raise self.retry(failed_items)

    return "sms(s) send successfully."

我想重试任务，但使用不同的数据集，只有失败的项目。

我的意思是如何实现这一目标：

raise self.retry(failed_items) ?

提前致谢。

Answer 1

@task()
def add(self, x, y):
    if not x or not y:
        try:
           raise Exception("test error")
        except Exception, e:
            add.retry(args=[x, y], exc=e, countdown=30)
    return x+y

Answer 2

@celery.task(bind=True, max_retries=2)
def send_sms(self,**kwargs):
    sms_list = kwargs.get("sms_list",[])
    failed_items = []
    for sms_item in sms_list:
        status = SendSMS( **sms_item )
        if status in ['Timeout','Error']:
            failed_items.append( sms_item )

    if len(failed_items) > 0:
        exc = Exception(status)
        raise self.retry( exc=exc, sms_list=failed_items)

    return "sms(s) send successfully."

Django Celery仅使用失败的数据集重试当前任务
