Question

Consider this small piece of code

from apscheduler.scheduler import Scheduler
import time

class First():
    def __init__(self):
        self.remove_job=None
    def go(self):
        self.remove_job('test')
class Sched():
    def __init__(self):
        self.sched = Scheduler()
        self.sched.add_interval_job(    self.execute,
                        seconds=1,
                        name = 'test'
                        )
    def execute(self):
        print "i'm alive"
    def remove_job(self,job):
        self.sched.print_jobs()
        self.sched.unschedule_job(job)

def main():
    first = First()
    sched = Sched()
    first.remove_job=sched.remove_job
    sched.sched.start()
    time.sleep(5)
    first.go()
    return 0

if __name__ == '__main__':
    main()

python sched_test.py 
i'm alive
i'm alive
i'm alive
i'm alive
i'm alive
Jobstore default:
    test (trigger: interval[0:00:01], next run at: 2011-12-22 01:25:36.577572)
Traceback (most recent call last):
  File "sched_test.py", line 55, in <module>
    main()
  File "sched_test.py", line 51, in main
    first.go()
  File "sched_test.py", line 31, in go
    self.remove_job('test')
  File "sched_test.py", line 43, in remove_job
    self.sched.unschedule_job(job)
  File "/usr/local/lib/python2.7/dist-packages/APScheduler-2.0.2-py2.7.egg/apscheduler/scheduler.py", line 401, in unschedule_job
    raise KeyError('Job "%s" is not scheduled in any job store' % job)
KeyError: 'Job "test" is not scheduled in any job store'

Why am I getting this error while printing out the jobs works?
print_jobs() gives me the right overview though.

Can someone shed some light on this problem?

Answer 1

you must pass the job instance (returned by add_interval_job) to unschedule_job instead of a string.
That fixes the problem.
