The scaffold in Rails 2.1 uses what is called Resources (
http://api.rubyonrails.org/classes/ActionController/Resources.html). In
your config/routes.rb, you should see a line like:

map.resources :recipes

To add a custom method outside the standard 7 (index, show, new, create,
edit, update, destroy), you need to tell resources about it. There are
2
different types of methods on a resource: collection and member. If the
action acts on multiple models, it’s a collection, if it acts on a
single
model (requires params[:id]), then it is a member.

map.resources :recipes, :collection => {:ingredients => :get}

Hope that helps,
Brandon
