This sounds like something that should be done with the scheduler.

One such thread is <URL:https://groups.google.com/d/topic/web2py/zgSLxeg7avw/discussion> That thread references using the scheduler, but doesn't show it ... the solutions show simulating progress by just bumping a session value each update. Updates are done using ajax with the browser, so there is some javascript on the client side. Your scheduler task could update the progress value based on which part of the computation it is in (or if there's just a big loop chewing on mouthfuls of data, do an "if loopindex % 50: update_progress_value(loopindex)". /dps -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.
