Overview

SlackNotification is a concrete class of Notification, sending notifications to the slack system. Initially this will be only used internally, however we could configure this to work with an account’s slack configuration.

This object allows you to create an EmailNotification object, set it’s property and tell it send_notification. It’ll handle everything from there including

  1. Running in the background thread

  2. Error recovery

  3. Retry on failure

Usage:

SlackNotification.say ‘Error getting data from resource’

or To change the channel it’s posted to…

SlackNotification.say ‘Error getting data from resource’, to: ‘another_channel’

or To who the message is from, the default is the environment name

SlackNotification.say ‘Error getting data from resource’, to: ‘another_channel’, from: ‘someone else’

You are done! Go about your business of creating awesome software!
