How is scaffold used?

Rails
1

I am new to Ruby on Rails. I have seen two kinds of using scaffold

  1. In a controller class to bind controller to its respective model as
    in
    class ContactController < ApplicationController
    scaffold contact # contact here is the name of the model called
    contact
    end

  2. scaffold is run from MS-DOS command line as in:
    ruby script/generate scaffold contact contact

When do you scaffold inside a class and when do you run scaffold from
command-line? Are there any other ways in which scaffold is done?

Thanks!

Hi Irene, welcome to the community.

  1. In a controller class to bind controller to its respective model as
    in
    class ContactController < ApplicationController
    scaffold contact # contact here is the name of the model called
    contact
    end

This style of scaffolding has been removed from Rails 2.0. It used to
be referred to as dynamic scaffolding, but it didn’t really help
people learn about Rails or give them a way to modify the generated
interface, so we killed it.

  1. scaffold is run from MS-DOS command line as in:
    ruby script/generate scaffold contact contact

This is the scaffold you want to use. If you run ‘ruby script/generate
scaffold’ you’ll get list of instructions on how to use it.
