Hi I'm using those 2 models: class Topic < ActiveRecord::Base has_many :articles, :order => :rank end class Article < ActiveRecord::Base belongs_to :topic, :counter_cache => true end The "counter_cache" column in the "topics" table does increase when adding a new article, but it does not update when updating article's topic or when deleting the article. Any idea ? _______________________________________________ Rails mailing list Rails-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org http://lists.rubyonrails.org/mailman/listinfo/rails
