What is Scaffolding in Rails6?

Scaffolding is the automatic generation of a simple set of a models, views, and controllers.

Let’s build an app in Rails6

Try the following commands in the terminal:

rails new newspaperstand

The above command will create the new newspaperstand project.

Go to the project directory.

cd newspaperstand

Before writing more code for the app, you need to create amodel and controllers using the rails generate command.

Create a model newspaper with the attributes (headline and publisher).

rails generate newspaper headline: string publisher: string
rails generate controller newspaper

Scaffolding can do all the work above in a single command.

Go ahed and try it in the terminal below.

rails new newspaperstand

cd newspaperstand

rails generate scaffold newspaper headline:text publisher:string

Your terminal output should be same as the output shown below:
