scheduler

[Frank]

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,

you're doing "all" wrong. Stop copy/pasting for a sec and take a look to docs.....it'll save you from multiple headaches.

in this case, you're "doing wrong" form processing.

It's either

form = SQLFORM(...)
if form.accepts(request.vars, session):
    ....things to do when form is valid
elif form.errors:
    ....things to do when form has errors
else:
    ....things to do when page is loaded the first time
return dict(form=form)

or (newer)

form = SQLFORM(...)
if form.process().accepted:
    ....things to do when form is valid
elif form.errors:
    ....things to do when form has errors
else:
    ....things to do when page is loaded the first time
return dict(form=form)

Despite my error, isn’t it normal doing some copy-past while giving  first steps?

in this case, you're "doing wrong" form processing.

It's either

form = SQLFORM(...)
if form.accepts(request.vars, session):
    ....things to do when form is valid
elif form.errors:
    ....things to do when form has errors
else:
    ....things to do when page is loaded the first time
return dict(form=form)


or (newer)

form = SQLFORM(...)
if form.process().accepted:
    ....things to do when form is valid
elif form.errors:
    ....things to do when form has errors
else:
    ....things to do when page is loaded the first time
return dict(form=form)


I’ve changed the code to this last newer form and it is working fine.

Yes It makes sense but I think what confuses me most is the ‘so many ways to do it’.

Meanwhile, looking here http://web2py.com/books/default/chapter/29/07/forms-and-validators I can’t figure where is the newer or ‘older’ version.

regards,

Frank

For some peoples, apparently : I'm just saying that you'll save headaches NOT copy/pasting :P

It's the first section on FORM and SQLFORM :D

web2py stack is huge. the documentation is also huge and detailed.
this is great but for newbies this is massive :)
hey this is not an escuse, I have too many things to learn and I am loving it.

Oh I see… I was understanding it wrong…
I though that in the handbook I would read a bold ‘deprecated’ vs ‘new way of doing things’.

Once again many thanks for your help and time :)
