Rails 7 doesn’t generate SCSS file on the `generate scaffold` command

Question

I created a new fresh project in Rails 7, and whenever I use the generating script

rails generate scaffold or rails generate controller , all of the generated files are created except the css/scss.

Apparently, I'm not the only one with the issue

There's a claim on that link that in Rails 7, the CSS files are not generated by default.

Is there a way to force rails CLI to generate styles on the scaffold command?

And in anyway, why did they make that change in Rails 7, if the claim is true?

Here's the script I ran and the output in my given console:

rails g scaffold WhyNoCss dont_work:boolean
  invoke  active_record
  create    db/migrate/20220215221757_create_why_no_csses.rb
  create    app/models/why_no_css.rb
  invoke    test_unit
  create      test/models/why_no_css_test.rb
  create      test/fixtures/why_no_csses.yml
  invoke  resource_route
   route    resources :why_no_csses
  invoke  scaffold_controller
  create    app/controllers/why_no_csses_controller.rb
  invoke    erb
  create      app/views/why_no_csses
  create      app/views/why_no_csses/index.html.erb
  create      app/views/why_no_csses/edit.html.erb
  create      app/views/why_no_csses/show.html.erb
  create      app/views/why_no_csses/new.html.erb

  create      test/system/why_no_csses_test.rb
  invoke    helper
  create      app/helpers/why_no_csses_helper.rb
  invoke      test_unit
  invoke    jbuilder

Is there a way to force rails CLI to generate styles?

While you can add --css sass (also: tailwind , postcss , bootstrap ) to rails new commands, the ability to generate CSS files with a scaffold command was removed in v7.0.0.alpha1 ( PR , commit ).

And in anyway, why did they make that change in Rails 7, if the claim is true?

You can read the justification on the PR in addition to their blog post on Rails 7 that mentions CSS changes.
