获取不能批量分配受保护的属性：地址

Question

我在日志中获取以下内容时尝试分配嵌套属性。我扫描并尝试了所有我能找到的答案，但没有任何效果。

Started POST "/admin/care_homes" for 127.0.0.1 at 2012-02-11 23:27:24 +0100 Processing by Admin::CareHomesController#create as HTML Parameters: {"utf8"=>"✓", "authenticity_token"=>"Zymx7VQU1mi+ho5T+Ups6cvHavpE4ClU6g1QFi+Y3z8=", "care_home"=>{"organisation_name"=>"", "cqc_id"=>"", "csa_id"=>"", "address"=>{"street_address"=>"", "address_line_two"=>"", "city"=>"", "county_id"=>"1", "postcode"=>""}, "registered_manager"=>"", "telephone_number"=>"", "website"=>"", "region_id"=>"1", "authority_id"=>"1", "provider_id"=>"11789", "details"=>"", "directions"=>""}} User Load (0.4ms) SELECT users .* FROM users WHERE users . id = 4 LIMIT 1

WARNING: Can't mass-assign protected attributes: address

我有一个CareTI的STI <服务。地址是一个多态关系。

在服务我：

class Service < ActiveRecord::Base 

    paginates_per 15 

    image_accessor :home_image 

    has_one :address, :as => :addressable, :validate => true 
    has_one :county, :through => :address 

    attr_accessible :organisation_name, :cqc_id, :csa_id, :registered_manager, 
       :telephone_number, 
       :website, :region_id, :authority_id, :provider_id, 
       :details, :directions, :home_image, :retained_home_image, 
       :county, :address_attributes 

    accepts_nested_attributes_for :address 

在CareHomeController＃新/创建我有

def new 
    @care_home = CareHome.new 
    @care_home.build_address 
end 

def create 
    @care_home = CareHome.new(params[:care_home]) 
    if @care_home.save 
    redirect_to admin_care_home_path(@care_home), :notice => 'Saved' 
    else 
    render 'new' 
    end 
end 


class Address < ActiveRecord::Base 

    attr_accessible :id, :street_address, :address_line_two, :city, :county_id, :postcode, :country_id, :addressable_id, :addressable_type 

    belongs_to :addressable, :polymorphic => true 
    belongs_to :county 

如果我添加：地址到attr_accessible我得到的错误：

Address(#2560574700) expected, got ActiveSupport::HashWithIndifferentAccess(#2157282280)

我的Rails版本是3.1.1。

我想这一定是微妙的，但我已经用尽了想法。任何帮助表示赞赏！

有什么理由你写attr_accesssible。

注释掉该行并尝试
