DeviseSlackNotifiable

Devise slack notifications gem. It posts message after registration and confirmation (if Devise confirmations strategy is enabled).

Installation

Add this line to your application's Gemfile:

gem 'devise_slack_notifiable'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install devise_slack_notifiable

Usage

1. Slack

Prepare Slack Webhook - it should look like https://hooks.slack.com/services/XXX/XXX/XXX.

Not sure how to do that? Check out slack documentation.

2. Application

After preparing Slack Webhook create initializer - config/initializers/devise_slack_notifiable.rb:

DeviseSlackNotifiable.configure do |config|
  # Enabled state
  #   By default integration is disabled. You need to enable it manually on desired environments.
  #   For example production only:
  #     config.enabled = Rails.env.production?
  #   Default: false
  config.enabled = true

  # Slack Webhook URL
  #   Required when integration enabled.
  #   It's recommended to use rails credentials instead of raw url (https://edgeguides.rubyonrails.org/security.html#custom-credentials)
  # Default: nil
  config.slack_webhook = 'YOUR_SLACK_WEBHOOK_URL'

  # Confirmation message state
  #   If You want You can disable sending confirmation message:
  #     config.confirmation_message_enabled
  #   Default: true

  # Context fields
  #   To all messages sent there is context attached that adds entity fields.
  #   If You want to customize fields:
  #     config.context_fields = [:id, :email, :first_name, :last_name]
  #   Default: [:id, :email]
end

After creating initializer add :slack_notifiable to the devise call in your model (we’re assuming here you already have a User model with some Devise modules):

class User < ActiveRecord::Base
  devise :database_authenticatable, :confirmable, :slack_notifiable
end

And you are ready to go!

Customization

Context

If You want to add more fields to context check out configuration in initializer - it's based on context_fields.

Example with context extended by first and last name (as on screenshots):

config.context_fields = [:id, :email, :first_name, :last_name]

Sending own messages

You can send own messages with this context for anywhere You want inside rails application:

# Let's assume that customer with id 1 asked for sales contact
user = User.find(1)
formatter = ->(entity) { "Customer #{entity.id} asked for sales contact!" }

notifier = DeviseSlackNotifiable::Notifier.new
notifier.send_message(user, formatter)

Message formatting

You can customize messages by initializer:

config.registration_message_formatter = lambda { |entity|
                                          "Yeah 🎉! Looks like we have new #{entity.model_name.human}! 😊"
                                        }

config.confirmation_message_formatter = lambda { |entity|
                                          "#{entity.model_name.human} have just confirmed his account 🥂"
                                        }
