Push notifications - proof of concept

[annaswims]

I'm not sure if I'm going to have a chance to implement this properly before I roll of my contract, but I expect someone will find this push notification proof of concept helpful. 90% of the effort was just finding the right documentation.

Presuming the apnotic gem is installed...

require 'apnotic'

# create a persistent connection
connection = Apnotic::Connection.new(cert_path: ENV.fetch('PASSKIT_PRIVATE_P12_CERTIFICATE'), cert_pass: ENV.fetch('PASSKIT_CERTIFICATE_KEY'))

# Simplest example  - get the correct token from the Device table
token = Passkit::Device.last.push_token

## Or,  more realistic token from app data:
# @generator = User.find 187
# push_tokens = @generator.passkit_passes.includes(:devices).collect{ |p| p.devices.pluck(:push_token)}.flatten
# token = push_tokens.first

## ensure that @generator has an updated created_at, so that the API returns an updated pass
# @generator.touch

# create a notification for a specific device token
notification       = Apnotic::Notification.new(token)
notification.topic = ENV.fetch('PASSKIT_PASS_TYPE_IDENTIFIER')

# send (this is a blocking call)
response = connection.push(notification)

## read the response, if you want
# response.ok?      # => true
# response.status   # => '200'
# response.headers  # => {":status"=>"200", "apns-id"=>"6f2cd350-bfad-4af0-a8bc-0d501e9e1799"}
# response.body     # => ""

# close the connection
connection.close

That's for sure helpful @annaswims ! Thank you. I'll close the issue because this should serve mostly as documentation anyway.
