芹菜:通过任务ID获取函数名称?

问题描述

我正在使用celery on_failure 处理程序，记录所有失败的任务以进行调试和分析.我想知道失败任务的任务名称(函数名称)，我该如何获取?

I am using celery on_failure handler to logging all failed tasks for debugging and analysis. And I want to know the task name(function name) of the failed task, how can I get that?

from celery import Task

class DebugTask(Task):
    abstract = True

    def after_return(self, *args, **kwargs):
        print('Task returned: {0!r}'.format(self.request))

    def on_failure(self, exc, task_id, args, kwargs, einfo):
        func_name = get_func_name_by_task_id(task_id) # how do I do this?
        print "{} failed".format(func_name)           # expected out: add failed.

@app.task(base=DebugTask)
def add(x, y):
    return x + y

PS:我知道有 task_id ，但是每次通过 task_id 来查询函数名称都不好玩，

PS: I know there is task_id, but query function name by task_id every time is not fun,

推荐答案

快速浏览文档显示 Task.name .

Quick look at the documentation shows Task.name.
