Yes  the scaffold itself and all the things that amalgamate it   The destroy command is the opposite of generate and will undo one  Just pass it the name the same way did with generate and it ll be scrubbed from your project   rails generate scaffold posts title string content text rails destroy scaffold posts title string content text

If you just want to see the files a generator will create you can pass the generator --pretend or -p option

Any time you run rails g  you can reverse it by running rails d  destroy  to remove what you ve generated  If you have already run rake db migrate  you will need to run rake db rollback before destroying

When we generate scaffold  following files will be created   Command  rails generate scaffold Game  Files created    gt        invoke  active record  gt        create    db migrate 20160905064128 create games rb  gt        create    app models game rb  gt        invoke    test unit  gt        create      test models game test rb  gt        create      test fixtures games yml  gt        invoke  resource route  gt         route    resources  games  gt        invoke  inherited resources controller  gt        create    app controllers games controller rb  gt        invoke    erb  gt        create      app views games  gt        create      app views games index html erb  gt        create      app views games edit html erb  gt        create      app views games show html erb  gt        create      app views games new html erb  gt        create      app views games  form html erb  gt        invoke    test unit  gt        create      test controllers games controller test rb  gt        invoke    helper  gt        create      app helpers games helper rb  gt        invoke      test unit  gt        create        test helpers games helper test rb  gt        invoke    jbuilder  gt        create      app views games index json jbuilder  gt        create      app views games show json jbuilder  gt        invoke  assets  gt        invoke    coffee  gt        create      app assets javascripts games js coffee  gt        invoke    scss  gt        create      app assets stylesheets games css scss  gt        invoke  scss  gt        create    app assets stylesheets scaffolds css scss   If we have run the migration after this then we have to rollback the migration first as the deletion of scaffold will remove the migration file too and we will not able to revert that migration   Incase we have run the migration   rake db rollback   and after this we can safely remove the scaffold by this commad   rails d scaffold Game   This command will remove all the files created by the scaffold in your project

Case 1  If you run only this command to generate scaffold -  rails generate scaffold MODEL NAME FIELD NAME DATATYPE  Ex - rails generate scaffold User name string address text   but till now you did not run any command for migration like   rake db migrate   then you should need to run only this command like -  rails destroy scaffold User name string address text   Case 2  If you already run Scaffold and Migration  by below commands like -  rails generate scaffold User name string address text  rake db migrate    Then you should need to run first rollback migration command then destroy scaffold like below -  rake db rollback  rails destroy scaffold User name string address text   So In this manner  we can undo scaffolding  Also we can use d for destroy and g for generate as a shortcut
