Yep,
1-Launch the scheduler on a command prompt
run cmd.exe or any terminal on your computer and type
python web2py.py -K myapp
2-Declare the scheduler on your models.
from gluon.scheduler import Scheduler
sched = Scheduler(db)
3.-Create a mailing function that will send the email in one of your models.
4.- Launch the scheduled task. Open another command prompt and type:
python web2py.py -a <your_password> -S <your_appname> -M
The scheduler should be avalaible as "sched". Start the task
task = sched.queue_task(my_mailing_function, .... parameters here according
to the signature)
db.commit()
and close the console. Look the table db.scheduler_task in your database to
confirm your task is running.
Scheduler signature:
scheduler.queue_task(
function,
pargs=[],
pvars={},
start_time=now, #datetime
stop_time = None, #datetime
timeout = 60, #seconds
prevent_drift=False,
period=60, #seconds
immediate=False,
repeats = 1 )
Yep, thats it, if it doesnt work you could use sched.queue_task within a
controller but you will have to check if the task is already declared or not.
Also the scheduler adds some overhead to the database, i dont like it, but its
ok if it works for you.
