How can I make scaffold only for controller and views if model already exists?

Question

I already have set up Devise to My App.
So User model is already generated, and exists by installing Devise

Now I'd like to add my own controller users_controller.rb and its views index and show.
How can I make scaffold without affecting to User model that already exists?

Answer 1

For scaffold with only 'name' column:

rails g scaffold User name --skip

Just add some columns.

Look to rails g scaffold -h output for additional information.
