Hi Niphlod,
      I need to get current task's id. I saw your sample scheduler example
on niphlod_w2p_scheduler_tests
<https://github.com/niphlod/w2p_scheduler_tests/blob/master/models/scheduler.py>
I did it in same way but got error.



*#models/scheduler.py*
def send_mail(to, subject, message, cc=None, bcc=None,
              attachments=None):
    """
    This module is called by scheduler.
    mail is queued by scheduler.
    """
    if cc is None:
        cc = []
    if bcc is None:
        bcc = []
    if attachments is None:
        attachments = []
    #sending mail
    print W2P_TASK
    result= mail.send(to=to, cc=cc, bcc=bcc,
                      subject=subject, message=message,
                      attachments=attachments)

    #if not result:
    #   print "FAILED: Task [%d]" % W2P_TASK.id
    ### update tasks' status


from gluon.scheduler import Scheduler
mail_scheduler = Scheduler(db, migrate=False)


I got following error

DEBUG:web2py.scheduler:    new task report: FAILED
DEBUG:web2py.scheduler:   traceback: Traceback (most recent call last):
  File "/home/prasad/Rootpy/web2py 2.3/gluon/scheduler.py", line 229, in
executor
    result = dumps(_function(*args, **vars))
  File "applications/lcm/models/scheduler.py", line 16, in send_mail
    print W2P_TASK
NameError: global name 'W2P_TASK' is not defined



if mail.send() fails due to some issue [for eg wrong password, port etc]
Still web2py scheduler mark current task as COMPLETED.

That's why I want to check mail.send's result.
If result is False then I've to update current task's status as Failed.
How do I get id of current task?

Thanks in advance.
