我有一個過很多:通過聯想,在其一側(ACCESSLEVEL)是定義模式「ACCESSLEVEL」,但對方可以爲多個資源軌道4 - 關聯 - 是否有可能在一個多方關聯的多邊形關聯?
設置我定義了一個特定的關注納入這些模型,並試圖用多態關聯
class AccessLevel < ActiveRecord::Base
has_many :allowed_activities
has_many :actionable, through: :allowed_activities
end
class AllowedActivity < ActiveRecord::Base
belongs_to :access_level
belongs_to :actionable, polymorphic: true
end
class <Model> < ActiveRecord::Base
include Authorizable
end
module Authorizable
extend ActiveSupport::Concern
included do
has_many :allowed_activities, as: :actionable
has_many :access_levels, through: :allowed_activities
end
end
是一個正確的實現還是我將提出一些意想不到的問題,抵押物?
