How to restart WebApp

[jeffwu]

Hi

I use AD2PI and run WebApp using the beta image on Jessie. What is the proper command line to restart web app?


thanks

Jeff

[jeffwu]

almost every Saturday morning I noticed keypad (web app) stuck in "Please wait. Loading.." state. rebooting pi would recover from it.

Is there a way I can restart web app instead of rebooting Pi as a whole?

after a reboot, I find below Errors in logs. were they expected?

hi

everyone to help out? after AlarmDecoder booting every Sunday, it stopped working. log on to web interface, the keypad in "Please wait. Loading.." state.

below is the last msg in /opt/alarmdecoder-webapp/instance/logs/info.log


2018-08-12 07:22:52,703 INFO: Event: Ready status has changed to True [in /opt/alarmdecoder-webapp/ad2web/notifications/types.py:371]
2018-08-12 07:23:30,887 INFO: Event: The AlarmDecoder has finished booting. [in /opt/alarmdecoder-webapp/ad2web/notifications/types.py:371]

Very frustrated. Webapp restarted again every Sunday morning. When this happens, the keypad no longer function.

Anyone can shed some lights here.
Either show me a way how to disable weekly restart,. Or fix this bug.

Suggest emailing support directly

Actually this should be public. I just did a fresh install Raspberry ISO / download , setup and update. Spent a lot of time setting up. Was working./
Then after a few reboots, web server not working. This happened on previous builds for years now.

I can SSH fine.
Now going to website , it just times out.
When it does come up, it just says;
" Services might still be starting - please wait and try again. If this continues, please let us know on GitHub. You can also email us at Support. "

How to reset alarmdecoder web app to default?

[wilsonb]

It works for a few minutes by resetting..
Broke again.. Please fix.

cd /opt/alarmdecoder-webapp
sudo rm instance/db.sqlite
python manage.py initdb
sudo reboot

[wilsonb]

Seems this python script is outdated;
python manage.py initdb

Result
ExtDeprecationWarning: Importing flask.ext.script is deprecated, use flask_script instead.

AFAIK this is a warning and did not effect the results but at some point it will break so lets get it fixed now.
I put this change in "dev" branch till I get a chance to tests it on older images.
