Slactionmailer

Slactionmailer is a mailer for ActionMailer that sends your message to a Slack channel.

Simple include the gem in your gemfile.

gem 'slactionmailer'

Or install from the command line.

gem install slactionmailer

In your environment or .env file, declare the name of your mailer variables:

SLACK_WEBHOOK_URL=your incoming webhook url
SLACK_CHANNEL=#your slack channel
SLACK_USERNAME=SlactionMailer (or whaterver you want to call it)

SLACK_CHANNEL and SLACK_WEBHOOK_URL are optional. If you do not set them here, you must pass in a webhook url and channel in your mailer.

Slactionmailer can be used as the default mailer

#config/environments/development.rb
config.action_mailer.delivery_method => :slack

Or only be used for certain messages

def notification
  mail(:from => 'from@example.com',           
       :to => 'to@example.com', 
       :subject => 'Subject',
       :delivery_method => :slack)
end

If you want to send messages to multiple channels, simply call the mail method with extra parameters:

def notification
  mail(:from => 'from@example.com',           
       :to => 'to@example.com', 
       :subject => 'Subject',
       :channel => '#yourChanel'
       :webhook => 'https://your-webhook-url'
       :delivery_method => :slack)
end

Your mailer messages will appear like this:

If you want to change the default message template, add the following to your config

config.slaction_mailer.template = File.read('my_template.text.erb')
