# Post error tickets to slack on a 5 minute schedule.
#
# Proper use depends on having created a web-hook through Slack, and having set
# that value in your app's model as the value of global_settings.slack_hook.
# Details on creating web-hooks can be found at https://slack.com/integrations
#
# requires the Requests module for posting to slack, other requirements are
# standard or provided by web2py
#
# Usage (on Unices), replace myapp with the name of your application and run:
#   nohup python web2py.py -S myapp -M -R scripts/tickets2slack.py &
