The counter cache is incremented when an object of this class is created and decremented when it‘s destroyed. This requires that a column named ”#{table_name}_count” (such as comments_count for a belonging Comment class) is used on the associate class (such as a Post class). You can also specify a custom counter cache column by given that name instead of a true/false value to this option (e.g., :counter_cache => :my_custom_counter.)</p>Konstantin Tumalevichtag:rubybrothers.ru,2007-04-24:192:1932007-04-24T18:51:37Z2007-04-24T18:51:37ZComment on 'Belongs_to :counter_cache' by Konstantin Tumalevich<p>А как поле называется, а то спать охота уже и в апи лазать не тянет))</p>
