has_many + foreign_key in ActiveRecord class not working

Mysql version 5.0.51a

I was unable to reproduce this bug in 2.3.3:

The two models:

@@@ Ruby class Entity < ActiveRecord::Base
set_table_name 'glpi_entities' has_many :trackings, :class_name => 'Tracking', :foreign_key => 'FK_entities' end

class Tracking < ActiveRecord::Base
set_table_name 'glpi_tracking' belongs_to :entity, :foreign_key => 'FK_entities' end

Console output:

entity = Entity.create => # 3.times { entity.trackings.create } => 3 entity.trackings => [#, #, #]

Formatting fail.

Models:

    class Entity < ActiveRecord::Base
      set_table_name 'glpi_entities'
      has_many :trackings, :class_name => 'Tracking', :foreign_key => 'FK_entities'
    end

    class Tracking < ActiveRecord::Base
      set_table_name 'glpi_tracking'
      belongs_to :entity, :foreign_key => 'FK_entities'
    end

Console output:

    Loading development environment (Rails 2.3.3)
    >> entity = Entity.create
    => #<Entity id: 1, created_at: "2009-08-08 14:49:11", updated_at: "2009-08-08 14:49:11">
    >> 3.times { entity.trackings.create }
    => 3
    >> entity.trackings
    => [#<Tracking id: 1, FK_entities: 1, created_at: "2009-08-08 14:49:25", updated_at: "2009-08-08 14:49:25">, #<Tracking id: 2, FK_entities: 1, created_at: "2009-08-08 14:49:25", updated_at: "2009-08-08 14:49:25">, #<Tracking id: 3, FK_entities: 1, created_at: "2009-08-08 14:49:25", updated_at: "2009-08-08 14:49:25">]

The id field was setted up as uppercase in the original database...

I've added set_primary_key :ID in each models.
It works now.

The ticket can be closed sorry for disturbing.
