No idea what you mean... Here's the code:
class Blog < ActiveRecord::Base
validates_presence_of :user_id, :title, :content
belongs_to :user
has_many :comments,
:as => :commentable,
:dependent => :destroy
end
class Comment < ActiveRecord::Base
validates_presence_of :commentable,
:subject,
:body
belongs_to :user
belongs_to :article
belongs_to :commentable, :polymorphic => true # Kann sowohl einem
Article als auch einem Blog zugehörig sein
def html_anchor
"comment-#{id}"
end
end
