REST
$ ruby script/generate scaffold_resource Model columnname:columntype
--skip-migration


The Payoff:
 * You get a starter set of functional tests for your controller. Keep your
 tests passing and you'll know your REST design is still intact.
 * A controller named Products with all of the canonical CRUD actions defined
 for you with boilerplate code. Comments with the routing paths (url pattern +
 http verb) to invoke that action. An HTTP XML API defined.
 * Boilerplate views for four of the CRUD actions (you'll just need to fill in
 your model's details in the forms).
 * A migration script. Define your table here, then run rake db:migrate.
 * map.resources :models line at the top of routes.rb.
