Scoping option_groups_from_collection_for_select
How can I scope the options returned by
option_groups_from_collection_for_select?
Method calls look like this: option_groups_from_collection_for_select
(collection, group_method, group_label_method, option_key_method,
option_value_method, selected_key = nil)
But say I want to limit the results returned by the option_key and
option_value methods to some particular scope?
For instance, using the sample code in rdoc:
class Continent < ActiveRecord::Base
has_many :countries
# attribs: id, name
end...
