ActiveRecord, has_many, polymorphic and STI
- by leomayleomay
I've came into a problem while working with AR and polymorphic, here's the description,
class Base < ActiveRecord::Base; end
class Subscription < Base
set_table_name :subscriptions
has_many :posts, :as => :subscriptable
end
class Post < ActiveRecord::Base
belongs_to :subscriptable, :polymorphic => true
end
in the console,
>> s = Subscription.create(:name => 'test')
>> s.posts.create(:name => 'foo', :body => 'bar')
and it created a Post like:
#<Post id: 1, name: "foo", body: "bar", subscriptable_type: "Base", subscriptable_id: 1, created_at: "2010-05-10 12:30:10", updated_at: "2010-05-10 12:30:10">
the subscriptable_type is Base but Subscription, anybody can give me a hand on this?
