Rails API-Only Social Login

This is another piece of code I've extrapolated from a Ruby on Rails project I'm currently working on. The code implmenets social login with a RoR API-based application, targeted at API clients.

The setup does not involve any browser-redirects or sessions as you would have to use working with Omniauth. Instead, what it does is takes an access_token generated on client-side SDKs, retireves user info from the access token and creates a new user and Identity in the database.

This setup works with native applications as described in the Google iOS Sign In Docs (see Authenticating with a backend server)

Writing your own delivery method in Rails (4.+)

Imagine, you got your rails server and you need to send out a bunch of mails to your recipients. no big deal, but SMTP is just very slow when compared with things like simple HTTP API calls.

I set out a few days to write my own delivery method, but found online sources somewhat lacking, outdated or completely skipping this part of sending mails in rails. So lets start making a simple mail_delivery method that outputs the mail to a file in your project home.

You can change the postman step in this tutorial to match your API, etc. instead.
