Is there any way to 'undo' the effects of a scaffold command in Rails?

To undo a rails generate command, run a rails destroy command. You can then edit the file and run rake db:migrate again. (See how to roll back a Migration file to rollback a specific migration or multiple migrations.)
Rails scaffolding is a quick way to generate some of the major pieces of an application. If you want to create the models, views, and controllers for a new resource in a single operation, scaffolding is the tool for the job.
First, if you have already run the migrations generated by the scaffold command, you have to perform a rollback first.
rake db:rollback You can create scaffolding using:
rails generate scaffold MyFoo (or similar), and you can destroy/undo it using
rails destroy scaffold MyFoo That will delete all the files created by generate, but not any additional changes you may have made manually.

Rishav Rastogi is right, and with rails 3.0 or higher its:
rails generate scaffold ...
rails destroy scaffold ...
