Rails Ruby on Rails

I have a basic rails project and run a generator

$ rails g scaffold foo name:string

Pretty straight forward. I am creating a Foo model with a name field. The controller runs fine however if I run the same command again say something like this (realizing that I forgot the age field):

$ rails g scaffold foo name:string age:string

I get the following error
Another migration is already named create_foos: /var/www/chimporter.com/db/migrate/20110329171246_create_foos.rb

The preferred action would be some sort of Do you want to override prompt that is common on the other controller actions. If I delete the above migration file I can then run the second migration and overwrite the existing files as expected.

Solution
Add an overwrite prompt to the active_record generator.
