                问题描述

                在芹菜中,如何跟踪当前重试?我知道我可以这样做:

                @app.task(bind=True, default_retry_delay=900, max_retries=5)
                def send_email(self, sender=None, to=None, subject=None, message=None):
                  try:
                    # Send email
                  except Exception as e:
                    # Print log message with current retry
                    self.retry(e)
                

                但我想说这是尝试1/5.2/5等等。

                推荐答案

                当前重试次数可以在任务的request.retries属性上找到。

                @app.task(retries=3, default_retry_delay=1)
                def fail():
                    try:
                        assert False
                    except Exception as e:
                      print 'Try {0}/{1}'.format(fail.request.retries, fail.max_retries)
                      # Print log message with current retry
                      raise fail.retry(exc=e)
                
                
                [2015-01-14 15:15:55,702: WARNING/Worker-1] Try 0/3
                [2015-01-14 15:15:58,604: WARNING/Worker-3] Try 1/3
                [2015-01-14 15:16:00,605: WARNING/Worker-2] Try 2/3
                [2015-01-14 15:16:02,607: WARNING/Worker-6] Try 3/3
                      
                

                芹菜内部使用类似的方法:https://github.com/celery/celery/blob/b0cfa0d818743262a032c541cce2fa8c43fabad4/celery/app/task.py#L558
