J'ai eu une situation similaire où j'ai eu des activités qui a une tâche qui a un affectables et la construction de la tâche serait aussi construire le affectables, comme ceci:Impossible de créer des associations polymorphes imbriquées '. Essayez-vous de construire un polymorphes un à une association

def new 
    @activity = Activity.new 
    @activity.task = @activity.build_task 
end 

maintenant, j'ai Conditions qui ont beaucoup TermTranslations qui ont beaucoup d'attachements qui ont un attaché (image ou audio), mais la ligne 18 @term = Term.new(permitted_params[:term]) admin/term.rb je reçois cette erreur:

Cannot build association `attachable'. Are you trying to build a polymorphic one-to-one association.

admin/terme .rb

    controller do

     tt.attachments.each do |a| 
      a.attachable = create_attachable(permitted_params[:term][:term_translations_attributes]) 
     end 
     end 

     if @term.save
