Ruby on rails 在单个rest调用中创建rest复杂资源实例

我想使用rails通过单个rest调用创建复杂的rest对象实例。 在下面的示例中，当我使用参数散列调用new on Person时，控制器中出现错误

当看到ActiveSupport:：HashWithInferenceTaccess而不是电话号码时，我收到一个意外类型的错误

从测试传递的哈希包含哈希对象数组，而控制器操作参数创建ActiveSupport:：HashWithInferenceAccess对象

有什么修正错误的建议吗

有没有更简单的方法通过一个rest调用创建复杂的activerecord对象 ie型号：

class Person < ActiveRecord::Base  
  has_many :phone_numbers , :autosave => true  

class PhoneNumber  < ActiveRecord::Base  
  belongs_to :person

迪纳提赫，谢谢你的回答！它帮助解决了这个问题

我遇到了一个小问题，因为“接受\u嵌套的\u属性\u用于：电话号码”， 需要散列键“phone_numbers_attributes”，而不是to_xml/to_json序列化默认值“phone_numbers”。下面的测试代码看起来有点难看，但是它通过并正确地创建了对象。不幸的是，将json传递给post方法也不会创建对象

test "should create complex person" do
  newperson=Person.new(:name => "test")
  newperson.phone_numbers.build(:number => "123-4567")
  person_string= newperson.to_xml(:include => :phone_numbers)
  person_hash=Hash.from_xml(person_string)
  person_hash2=person_hash['person']
  person_hash2[:phone_numbers_attributes] = person_hash2['phone_numbers']
  person_hash2.delete('phone_numbers')
  p person_hash2
  post :create, :person => person_hash2, :format => "xml"
  p response.body
  assert_select "person" do
    assert_select "name", {:text=>"test"}
    assert_select "phone-numbers" do
      assert_select "phone-number" do
        assert_select "number", {:text=>"123-4567"}
      end
    end
  end
  assert_response :success
end
