有没有人找到为 ActiveRecord 多态关联编写 rspec 示例的方法?

我习惯使用 Thoughtbot 的应该匹配,但我认为多态超出了它的范围?

为清楚起见,我的模型将具有与此类似的模式:

class Person < ActiveRecord::Base
  attr_accessible :name

  has_one :address, as: :location_data_source

  accepts_nested_attributes_for :address
end

class Company < ActiveRecord::Base
  attr_accessible :name

  has_one :address, as: :location_data_source

  accepts_nested_attributes_for :address
end

class Address < ActiveRecord::Base
  attr_accessible :street, :city

  belongs_to :location_data_source, polymorphic: true
end
