Scheduler is Not Running

[Suhas Jadhav]

Hi,

I have following code 

def fun1:

    do something

    returns locals()

I have below code in scheduler.py

def hcstar():
    LOAD('monitoring',' fun1')

from gluon.scheduler import Scheduler
    scheduler2 = Scheduler(db,tasks=dict(hcstar=hcstar,fun1=func2))

I have scheduled the task to run every 5 min.

I can see the task is changing the status as ASSIGNED-->QUEUED 

But I do not see the record being inserted into  db.scheduler_run 

 Also function  fun1  is not being called.

Can anybody help.

From your defuns, neither hcstar nor fun1 appear to be task-like.  Tasks do not talk directly to a client ("the user"); instead they perform work on files or database entries or some such.  The scheduler will record their "stdout" (print statements, etc) and if the task returns a string or boolean.  If you're just trying to get familiar with setting up tasks, a function that does a print("Hello from taskA") and returns a True will work nicely.

The other part of the equation is that you have to have a thread or job running somewhere to launch the workers.  That's the job of the -K command line parameter.

I have scheduled the task to run every 5 min.

HI Dave,

How do I make hcstar  as a task. What is wrong in my code?

Thanks,

Suhas

The LOAD() helper is meant to be used in a view.  It isn't a useful tool in a task.  A task has no client, and no user interface.  Your controllers handle the client side, and use a task to handle something "behind the curtain", like a long-running computation, or generating reports based on recent database entries, or fetching remote resources.  The controller function can watch for task completion if the results need to be shown to the user.

What are you trying to do with a task?
