Fernando,

Tá sim.

Os métodos de relacionamentos estao todos funcionando e testados. por exemplo:

Criei no banco uma AnnoncersCategory com nome = “a”.
Criei tb 2 AnnouncersSubCategory com nomes “a1” e “a2”, ambas relacionadas a “a”

daí:

AnnouncersCategory.find(:first)

=> #<AnnouncersCategory id: 1, name: “a”, created_at: “2009-01-16 13:19:39”, updated_at: “2009-01-16 13:19:39”>

AnnouncersCategory.find(:first).announcers_sub_categories

=> [#<AnnouncersSubCategory id: 1, name: “a1”, announcers_category_id: 1, created_at: “2009-01-16 13:19:52”, updated_at: “2009-01-16 13:19:52”>, #<AnnouncersSubCategory id: 2, name: “a2”, announcers_category_id: 1, created_at: “2009-01-16 13:19:57”, updated_at: “2009-01-16 13:19:57”>]

e

Na linha :
has_many :announcers_sub_categories, :dependent => :restrict

Qdo coloco :destroy no lugar de :restrict o delete cascade funfa legal …

Tópico: :dependent => :restrict

class Announcer < ActiveRecord::Base
belongs_to :announcers_category
belongs_to :announcers_sub_category
belongs_to :local
end

class AnnouncersCategory < ActiveRecord::Base
has_many :announcers_sub_categories, :dependent => :restrict
has_many :announcers
end

class AnnouncersSubCategory < ActiveRecord::Base
belongs_to :announcers_category
has_many :announcers
end

O teste:

com categoria e subcategorias associadas no banco.

a = AnnouncersCategory.find(:first)
a.destroy
