I met this problem due to the 'multiple database support issue'. In my `app/model` folder, there is a file defined a redundant database connection:
class CacheCleanerActiveRecord < ActiveRecord::Base establish_connection "cache_cleaner_#{Rails.env}" self.abstract_class = true end
but this database is not found in my database.yml ( because it's not used at all ).
so the solution is quit simple: remove this file and everything is fine !
