Question

For example, I created this post_controller earlier in the project but I decide to destroy it later.

Then I use

rails destroy controller post_controller

to remove the controller. But I also want to remove the views that attach to this controller.
In this case, they are the erb files in the app/views/post folder. How can I remove those erb files?

You can run rails d scaffold post but be warned this will destroy the rest of the scaffolded elements including any models/routes/assets etc. Here is the full list of what it will destroy:

⌘ ~/testapp/ rails d scaffold post
  invoke  active_record
  remove    migration.rb
  remove    app/models/post_controller.rb
  invoke    test_unit
  remove      test/unit/post_controller_test.rb
  remove      test/fixtures/post_controllers.yml
  invoke  resource_route
   route    resources :post_controllers
  invoke  scaffold_controller
  remove    app/controllers/post_controllers_controller.rb
  invoke    erb
  remove      app/views/post_controllers
  remove      app/views/post_controllers/index.html.erb
  remove      app/views/post_controllers/edit.html.erb
  remove      app/views/post_controllers/show.html.erb
  remove      app/views/post_controllers/new.html.erb
  remove      app/views/post_controllers/_form.html.erb
  invoke    test_unit
  remove      test/functional/post_controllers_controller_test.rb
  invoke    helper
  remove      app/helpers/post_controllers_helper.rb
  invoke      test_unit
  remove        test/unit/helpers/post_controllers_helper_test.rb
  invoke  assets
  invoke    coffee
  remove      app/assets/javascripts/post_controllers.js.coffee
  invoke    scss
  remove      app/assets/stylesheets/post_controllers.css.scss
  invoke  scss

Edit:

To clarify, rails d is just shorthand for rails destroy. It can also be used as rails generate/ rails g.
