本文介绍在Ruby on Rails应用中使用单表继承(STI)时如何配置属性赋值的安全策略，包括mass assignment sanitizer的设置方法及PhoneNumbersController的具体实现细节。

环境变量：

  config.active_record.mass_assignment_sanitizer = :logger # :restrict
in application.rb:
  config.active_record.whitelist_attributes = false

子类代码：


class Agent < Profile

  has_many :phone_numbers 
  children :phone_numbers  
  # The other recipe(s) say leave the sub-class models empty, but
  # I needed both these lines to make the app work.


    mass_assignment_sanitizer - Defines sanitize method. Possible values are:

        :logger (default) - writes filtered attributes to logger

        :strict - raise ActiveModel::MassAssignmentSecurity::Error on any protected attribute update


class PhoneNumbersController < ApplicationController

  hobo_model_controller

  auto_actions :all

  auto_actions_for :profile , :create
  auto_actions_for :agent , :create
  auto_actions_for :client , :create
  auto_actions_for :cooperating_agent , :create

end


class Profile < ActiveRecord::Base

  hobo_model # Don't put anything above this

  fields do
    name   :string
    street :string
    sti_type :string
    timestamps
  end
  attr_accessible :name, :street,:sti_type

  set_inheritance_column :sti_type

  has_many :phone_numbers
  children :phone_numbers
end
