[web2py] any ideas for printing stdout to the web interface?
I run a script that prints to stdout, but I'd like to have a modal popup and have all the information displayed to the user while the script is running.

[web2py] Re: any ideas for printing stdout to the web interface?
well, imagine i'm doing
for i in range(0,10):
print(i)
There are hundreds of logging functions inside of the script, so it'd be a
bit much for here.
I know I can do that exact command as {{for i in range(0,10):}}
{{=i}}
{{pass}}
but I would like to have a way to dynamically print stuff to the web
interface. Maybe using ajax? I'm just not sure where to start...

This shouldn't be necessary. As long as you have the client id available in
the request (e.g., in auth.user.client), you can simply use it to specify
the uploadfolder when defining the model. In db.by:
db.define_table('company',
Field('logo', 'upload', label='Company Logo',
uploadfolder=os.path.join(request.folder, 'uploads', auth.user.client
if auth.user else ''),
uploadseparate=True, autodelete=True)),
...)

[web2py] Re: Issues with Scheduler (suddenly multiple tickers appear)
So I narrowed down the issue, it happends when a worker detects he should be the ticker and does an update on all other workers to set them false, an oracle error happens (about deadlock) and it fails, the error "Error coordinating ticker" appears and then it continues, but lines later it COMMITS and makes itself a ticker... and everyone wants to be a ticker and scheduler dies and fire starts and i suffer in pain, so the fix should be removing the catch that prints the message "Error coordinating ticker" so that when the whole operation fails it rolls back and not commits itself to be a ticker.. anyways issue is open now: https://github.com/web2py/web2py/issues/1787 El miércoles, 4 de octubre de 2017, 8:49:22 (UTC-6), Boris Aramis Aguilar Rodríguez escribió: > > Hi, I've been recently using lots of tasks scheduled on a server so I had > to use several workers to deal with the queue, currently I'm using 45 > workers. > > Somewhere between 12 hours after starting the 45 workers, suddenly tasks > start accumulating in the queue and workers are alive (they report a > heartbeat), and the only thing i've noticed is that from the 45 workers > more than 1 becomes the ticker (the flag is_ticker is True for several of > them), so if I discovered that if I set to False the flag for all workers > except for one then tasks start being assigned again correctly, but it > happends again after some time. > > I'm not sure how to find where the bug is, so that is why I come here > asking for your guidance :) > > Thanks! > -- 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.

Thank you all! > You may want to make use of a logging module. The standard logging in web2py will go to a file (using the name in the as-shipped logging.conf unless you edit that), but it shouldn't be too hard to swap in something to send to a websocket instead. Add your handler's name to logging.conf under the handlers section and under the logger_myapp section and add a handler_mywebsocks section. I see on my Fedora system that /usr/lib64/python2.7/logging/handlers.py has a SocketHandler class which might be a starting point. /dps > On Tuesday, October 10, 2017 at 3:13:08 PM UTC-4, Dave S wrote: >> >> >> >> On Tuesday, October 10, 2017 at 9:46:33 AM UTC-7, LoveWeb2py wrote: >>> >>> I run a script that prints to stdout, but I'd like to have a modal popup >>> and have all the information displayed to the user while the script is >>> running. >>> >>> Anyone have any ideas on how to achieve this within web2py? >>> >>> >> There are 2 mechanism in HTML5, I believe, but I'm only going to point >> you at one for the moment: Web Workers. >> > http://www.htmlgoodies.com/html5/javascript/working-with-web-workers-in-html5-powered-web-pages.html >> > >> > http://www.htmlgoodies.com/HTML5/client/introduction-to-html5-web-workers-the-javascript-multi-threading-approach.html >> > >> > http://www.htmlgoodies.com/html5/other/html5-tech-shared-web-workers-help-spread-the-news.html >> > >> >> With this mechanism, you'd spawn a web worker to do jquery/ajax to check >> when it was time to replace the content.

The standard logging using the as-shipped logging.conf will both go to a file (using a default name from the as-shipped logging.conf) and to the console. Editing logging.conf can a) remove either handler, b) change the name of the file, c) replace one handler with another, or d) add an additional handler.
