我正在尝试使用以下代码重试失败的任务:
@task(bind=True)
def update_listing(self, listing_object, retailer):
try:
listing = _update_listing(listing_object, retailer)
except Exception as exc:
raise self.retry(exc=exc)
return listing
这会导致抛出以下错误:
Reject: (TypeError('__init__() takes exactly 2 arguments (3 given)',), True)
我不能解决这个错误,或者我如何解决它。我是否以正确的方式调用重试方法?
我的芹菜配置文件如下所示:
BROKER_URL = "redis://localhost:6379/0"
CELERY_IMPORTS = ("tasks", )
CELERY_RESULT_BACKEND = "redis://localhost:6379/0"
CELERY_IGNORE_RESULT = True
编辑:完整堆栈跟踪:
Traceback (most recent call last):

R = retval = fun(*args, **kwargs)

答案 0 :(得分:1)
你不能使用常规功能使用的@task
装饰器来装饰实例方法。你将不得不使用
from celery.contrib.methods import task
而不是常规的:
from celery import task
它可能有一些警告,因为它是3.0版以来的实验,请参考此链接:
