在我的Rails 4.2.7，紅寶石2.3.3應用程序，當我保存特定的多態關聯通過保存的嵌套形式，它給堆棧層次過深的錯誤和rails_admin停止響應。當我從Rails控制檯保存時，它會給出以下錯誤，致命錯誤：重新出現異常錯誤。異常再進入：當保存多態關聯
2.3.3 :001 > Post.last.links

這裏是
class Link < ActiveRecord::Base
extend Enumerize
enumerize :target, in: [:_blank, :_self, :_top, :_parent], default: :_blank
# Associations
belongs_to :linked_item, polymorphic: true, touch: true
# Validations
validates_presence_of :link
validates_presence_of :name
validates :link, :url => { allow_nil: false }
# Scopes
scope :sorted, -> { order(created_at: :asc) }
end
這完全相同的代碼被部署在Heroku我的Post模型
class Post < ActiveRecord::Base
has_many :links, -> { order(created_at: :asc) }, as: :linked_item, dependent: :destroy
accepts_nested_attributes_for :links, allow_destroy: true
我的鏈接模型的相關部分，它工作正常，但在我的本地機器，它不工作。 而當軌道服務器停止響應那麼我殺掉進程和它說

和令人驚訝的我的測試都通過，但我不能夠通過Rails的控制檯或rails_admin面板添加任何東西到具有模型通過填充嵌套形式來實現多態關聯。
感謝，
