2: CRUD, Validations, and Partials

Let's continue by working on the MVP functionality for our application. We'll be adding the Shout model to our application. We'll talk about the correct ways to write migrations and validations. We'll also get to make use of routing constraints, a way to specify which routes should be active as well as partials. Additionally, we'll briefly discuss the Law of Demeter and how we can apply it to writing our applications.
