Hi,
/newbie here/
I’ve up and running a very very simple task scheduler but I think it’s not well
designed :/
under models/scheduler.py I have:
"
from gluon.scheduler import Scheduler
def task_add(name, target):
sum = 'hello ' + name + ' ' + target + '\n'
with open('/tmp/tasks', 'w') as f:
f.write(sum)
scheduler = Scheduler(db, dict(task_add=task_add))
“
and in controller:
“
def new():
form = SQLFORM(db.scan)
name = “”
target = “"
if form.process().accepts(request.vars, session):
name = form.vars.name
target = form.vars.target
response.flash = ‘Great scan'
elif form.errors:
response.flash = 'Error, try again'
scheduler.queue_task('task_add’,
pargs=[],
pvars={'name': name, 'target': target},
start_time=request.now, #datetime
stop_time = None, #datetime
timeout = 60, #seconds
prevent_drift=False,
period=60, #seconds
immediate=False,
repeats = 1)
return dict(scans=scans, form=form)
“
This snippet is working but I think this “scheduler.queue_task(…)” should be
processed inside “if form.process().accepts()”. But if I change the scheduler
snipper into that code section, the task wont run and I don’t know why.
two: questions
1) what I am doing wrong?
1.1) Maybe I should db.commit when the task is over. Should I code this under
scheduler.py?
2) where can I learn more about debugging?
Many many thanks in advance :)
Cheers,
