Action Notifier

Action Notifier is a small framework for sending push notifications in a way very similar to Action Mailer.

Analogous to Action Mailer, start by creating an ApplicationNotifier in a new app/notifiers directory in your Rails project.

class ApplicationNotifier < ActionNotifier::Base
  # ActionNotifier::Base has a method notify(app, device_token, message, custom = {})
  # so you will probably need a method that finds the (Rpush) app and the
  # device token (could also be several) to notify a given user. ActionNotifier
  # doesn't know how you store your device tokens, so you need to do the
  # translation yourself.
  #
  # The below implementation is an example where device tokens are stored in
  # a table devices(user_id, type, token) where type is the Rpush app name.
  # In the example we notify all of a user's registered devices.
  def notify(user, message, custom = {})
    user.devices.find_each do |device|
      super(Rpush::App.find_by(name: device.type), device.token, message, custom)
    end
  end
end

Then create notifiers much as you would mailers in Action Mailer. For example, a social networking app may have an app/notifiers/friend_notifier.rb:

class FriendNotifier < ApplicationNotifier
  def new_friend(user, friend)
    notify(user, "#{friend.name} added you as a friend!")
  end
end

Whenever you then want to notify the user, you do

FriendNotifier.new_friend(user, friend)

Add this line to your application's Gemfile:

gem 'actionnotifier'

And then execute:

$ bundle

Or install it yourself as:

$ gem install actionnotifer

This section is for people who want to do development work on Action Notifier (highly encouraged!).

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
