如何从代码中读取失败队列的回溯？

Question

我在队列失败时失败 1次.

$ rq info
failed       |? 1

1 queues, 1 jobs total

作为回答的@Byron露丝,我能得到这个数字是这样的:

from rq import Queue
from redis import Redis

q = Queue('failed', connection=Redis())
print len (q.jobs)

在rq-dashboard上,我看到了回溯:

Traceback (most recent call last):
  File "/usr/local/lib/python2.7/dist-packages/rq/worker.py", line 588, in perform_job
    rv = job.perform()
    ...

如何使用Python代码获取此回溯？如果这是不可能的,任何命令行解决方案都是可接受的(如Bash或类似的).

不确定您是否找到了解决方案.您可以从exc_info通话中获取追溯.例如:

>>> print(get_failed_queue().jobs[0].exc_info)
Traceback (most recent call last):
  File "/Users/ubuntu/.venv/lib/python3.5/site-packages/rq/worker.py", line 700, in perform_job
    rv = job.perform()
  File "/Users/ubuntu/.venv/lib/python3.5/site-packages/rq/job.py", line 500, in perform
    self._result = self.func(*self.args, **self.kwargs)
  File "/Users/ubuntu/foo.py", line 17, in foobar
    1/0
ZeroDivisionError: division by zero
