Kad,
If you want to initialize the counter cache after having modified the db schema, simply run set the value in the migration like:
class AddArticlesCounterCache < ActiveRecord::Migration def self.up add_column :blogs, :articles_count, :integer
for blog in Blog.find(:all) do blog.articles_count = blog.articles.size blog.save end end
def self.down remove_column :blogs, :articles_count end end
