Comment faire has_many avec un modèle qui est dans un espace de noms

Question

Rails 3 nous a donné ces générateurs sympas qui placent des modèles et des contrôleurs dans des espaces de noms, whoo! Mais maintenant je suis incapable de les associer avec d'autres modèles. J'essaie d'obtenir une association has_many through avec les modèles à espaces de noms. J'ai cherché sur Internet pendant quelques jours et je n'ai pas trouvé d'exemples.

/app/models/templates/practice.rb

class Templates::Practice < ActiveRecord::Base 
    has_many :practice_sequences, :order => "position", :dependent => :destroy, :class => 'Templates::PracticeSequence' 
    has_many :seasons, :through => :practice_sequences, :order => "position", :class => 'Templates::Season' 
end 

/app/models/templates/season.rb

class Templates::Season < ActiveRecord::Base 
    has_many :practice_sequences, :order => "position", :class => 'Templates::PracticeSequence' 
    has_many :practices, :through => :practice_sequences, :order => "position", :class => 'Templates::Practice' 
end 

/app/models/templates/practice_season.rb

class Templates::PracticeSequence < ActiveRecord::Base 
    belongs_to :practice, :class => 'Templates::Practice' 
    belongs_to :season, :class => 'Templates::Season' 
end 

Et voici l'erreur

Je n'ai pas essayé d'utiliser les espaces de noms pour les modèles moi-même, mais lorsque vous spécifiez une classe pour une association, vous devez utiliser: class_name au lieu de: class. Le reste me semble bon, alors c'est peut-être la seule chose que vous devez changer.
