How to use scheduler in modules ?

[António Ramos]

Hello i already have in a model

from gluon.scheduler import Scheduler

scheduler = Scheduler(db)

  Then i have a module where i need to 

scheduler.queue_task(task_add, pvars=dict(a=1, b=2))

I get scheduler not define.

how can i use scheduler inside a module?

i added in a model 

current.scheduler=scheduler

and then 

in a module

scheduler=current.scheduler

...

It works... but dont know if thats the best option...

But if i do

scheduler.queue_task(task_add, pvars=dict(a=1, b=2))

task_add must reside in the same file as the scheduler initialization code.

I have many controllers and modules as independent apps. All of them can ask scheduler to start a task.

What should i do ?

Hi. It is not necessary to have task_add in same file, where scheduler initialiazed. Your solution with "current" is right. Add tasks and queue them anywhere!

Which can look something like this

   def modfuncx(u, y,z):
       fdir,fn,ext = compute(y,z)
       tid = current.scheduler.queue_task('play_fetch', pvars={'uval': u, 'path': fdir+fn+ext}, timeout=1200)
       return fn, ext

(based on one of my projects)
