MyWordList with UUIDs for Primary Keys

Using the book, "Frontend-friendly Rails" as a reference, I'm planning to build a backend Rails API that is only loosely coupled with a JS framework frontend. To achieve this the app will:

• use client-generated uuids, when creating resources, as primary keys in an activerecord database,
• the Rails (4.2.6) API will provide JSON endpoints for a frontend framework to consume (probably React).

Running locally

• install postgresql
• bundle install
• start a local postgres server: postgres
• start a local rails server: rails s
• navigate to localhost: 3000

Tests

bundle exec rspec
