我正在努力将电话号码与志愿者(以及后来的其他事情)进行多态关联,目前我遇到了以下错误:

uninitialized constant HumanVolunteer::PrimaryPhone
app/controllers/human_volunteers_controller.rb:44:in `new'
app/controllers/human_volunteers_controller.rb:44:in `create'

这是我的PhoneNumbers模型:

class PhoneNumber < ActiveRecord::Base
  attr_accessible :notes, :number

  belongs_to :phone, :polymorphic => true
end

这是我的HumanVolunteers模型:

class HumanVolunteer < ActiveRecord::Base

  attr_accessible :firstName, :lastName, :homeaddressid, :notes, :status, :workdaddressid, :home_adr, :work_adr, :primaryPhone
  has_one :primaryPhone, :as => :phone

  def home_adr=(home_adr_arg)
    # Home ADR
    home_adr = Address.new(home_adr_arg)
    if home_adr.save 
      self.homeaddressid = home_adr.id
    end
  end

  def work_adr=(work_adr_arg)
    # Work ADR
    work_adr = Address.new(work_adr_arg)
    if home_adr.save 
      self.workaddressid = work_adr.id
    end
  end
end

我的电话号码和人工志愿者的架构:

表:human_volunteers

id  integer 
status  character varying(255) …
