Did the scaffold do all that?

Hey there David,

yes, scaffolding is a quick way to get the basic structure of a Rails application. As far as I understand it a scaffold creates everything you need to get started for you like the Model, Views, Controllers and a database migration. However the created application you can see in your browser is more of an example, it just shows you that there is a working CRUD (Create, Read, Update, Delete) structure and it's not more than a starting point. So probably you'll want to start from scratch with the scaffold as a base and not use the site the scaffold created as your own application.

And unfortunately I have to disagree with Jason, while I absolutely agree and recommend that you learn Ruby before Rails (if you haven't done so already) I think that scaffolding itself has nothing to do with the language Ruby but more with the framework Ruby on Rails so I don't think you'll learn what scaffolding is and how it works in the Ruby courses.

I hope that helps!

You better start with this course before you move to ruby on rails. rails is framework. Basically a huge written library that lets you use methods to create an app.
