Hi,
I've web2py 2.3 version. I tried to use scheduler for mail sending.
I got this error while creating a worker for scheduler
$ python web2py.py -K send_mail_app

OperationalError: (1050, "Table 'scheduler_task' already exists")
I've followed following instructions.
*1) Created a file models/scheduler.py*
#code from scheduler.py file
from gluon.scheduler import Scheduler
mail_scheduler = Scheduler(db)
def send_mail(to, subject, message, cc=None, bcc=None,
attachments=None):
"""
This module is called by scheduler.
You can check scheduler_task table and scheduler.task_status table
"""
if cc is None:
cc = []
if bcc is None:
bcc = []
if attachments is None:
attachments = []
#sending mail
mail.send(to=to, cc=cc, bcc=bcc,
subject=subject, message=message,
attachments=attachments)
*2) Called send_mail module in an external script.*
(scripts/send_mails.py)
#extra code here
task = mail_scheduler.queue_task('send_mail',
pvars={'to': email,
'subject': subject,
'message': html_email},
start_time=datetime.datetime.now())
print task
*3) Created a worker and got above error*
Am I missing some steps?
