Fix bug where reset_counters resets the wrong counter cache. If a model belongs_to two associations with the same class, then reset_counters will reset the wrong counter cache. Finding the right reflection should use the foreign_key instead, which should be unique. 2012-01-17 02:06:14 +00:00			`class Dog < ActiveRecord::Base`
