So I have received no recommendation to this.
There was no problem with the systemd service,
but (to be more portable,...) I have moved now to the scheduler.
If somebody is interested, here is my code.
I can/need initialize the scheduler with one (admins) access to url
myapp/sysadmin/start_idx.
@auth.requires_membership('admin')
def start_idx():
if DEBUG_SCHEDULER:
idx()
return 'Indexing finished.'
else:
if db((db.scheduler_task.application_name == 'codex2020/sysadmin') &
(db.scheduler_task.task_name == 'idx')).select().first():
return 'Task idx already queued. Remove it from scheduler_task
table if you want re-create it.'
else:
scheduler.queue_task(
idx,
pargs=[],
pvars={},
start_time=datetime.datetime.now(),
stop_time=None,
timeout=2147483647,
prevent_drift=False,
period=20,
immediate=False,
repeats=0
)
return 'Task idx was added.'
