I am for the first time trying to use the scheduler and so far it was
unsuccessful :(
I have watched the video on vimeo on the scheduler and I suspect that is a
bit old.
I have read what was written in the book as well as the docstrings in
gluon/scheduler.py.
I have entered two functions in <app>/models/scheduler.py and have added
them using:
from gluon.scheduler import Scheduler
myscheduler = Scheduler(db,dict(nr_arts_per_journal=art_pp, publishers = pbs
))
This did not add anything to the table db.scheduler_task. Is that normal?
So I used the appadmin interface to add them the functions.
Some options are not clear to me:
1. The default entry in the field application_name is '<app>/appadmin'.
Why is /appadmin added? I suspect I should enter the app name there.
2. What 'repeats' mean is not clear to me.
2.1 Does that mean 'repeat x number of times in the period' for each
period?
2.2 What does -0 (unlimited) mean in relation to period? Does that mean:
try as many as you can within the period? Or: repeat until ended otherwise
once per period?
3. In the video, the command 'python web2py.py -K <app>' showd some info
about the runs. I have started the worker and nothing is showing but:
'starting single-scheduler for "akb"...'
How do I get the worker to be more verbose?
4. I have the following entries in db.scheduler_task:
scheduler_task.application_name scheduler_task.task_name
scheduler_task.function_name scheduler_task.repeats
scheduler_task.retry_failed scheduler_task.period scheduler_task.timeout
akb Number of articles per publication nr_arts_per_journal 3 -1 180 120 akb
Publishers publishers 1 0 7200 120
The absent fields were either NULL or the default values. Both functions
were queued and enabled.
Although I have started the worker (python web2py.py -K akb) nothing is
happening.
How do I get the scheduler to handle those tasks?
Are my options wrong?
Regards
Johann
