What I do currently: create a scheduler in a dedicated model:
from gluon.scheduler import Scheduler
from jobs import testfunc
scheduler = Scheduler(db, dict(testfunc_task=testfunc))
Then in a controller, I do:
task_kwargs = { 'immediate': True, 'task_name': 'ImportContacts-' +
str(time.time())[:-4], }
from jobs import testfunc
scheduler.queue_task(testfunc, pargs=[request.vars.sna],
kwargs=task_kwargs)
and I get an exception saying that table socialjack.scheduler_task does not
exist (traceback below). But the table IS there, I can see it in the db
admin interface and on the MySQL console ... Please help! Thanks!
