建立不保存的多态关联

Question

我正在尝试为User建立一个多态地址，但是它不能正常工作。 我可以创建多态对象，但是它不能保存所有参数，而且我也不知道为什么！并且显示“缺少参数或值为空：地址”

创建并保存新用户时，不要保存地址的所有参数，仅保存“ addresseable_type和addresseable_id”。

地址模型

class Address < ApplicationRecord
    belongs_to :addresseable, polymorphic: true
end

用户模型

class User < ApplicationRecord
    has_one  :address, :as => :addresseable, dependent: :destroy

    has_secure_password
end

用户控制器

class UsersController < ApplicationController
    before_action :authorize_session
    before_action :set_user, only: [:show, :edit, :update]

    def show
    end

    def new
        @user = User.new
        @user.build_address
    end

    def create
        @user = User.new(user_params)
        respond_to do |format|
            if @user.save
                if @user.build_address(address_params).save
                    format.html { redirect_to "/users", notice: 'Success!' }
                end
            else
                format.html { render :new }
                format.json { render json: @user.errors.full_messages, status: :unprocessable_entity }
            end
        end
    end

    def edit
    end

    def update
        respond_to do |format|
            if @user.update(user_params)
                format.html { redirect_to "/users", notice: 'Success!' }
            else
                format.html { render :edit }
            end
        end
    end


    private

    def set_user
        @user = User.find(params[:id])
    end

    def user_params
        params.require(:user).permit(:name, :date_of_birth, :email, :password, :password_confirmation)
    end

    def address_params
        params.require(:address).permit(:id, :address, :address_number, :extra_info, :neighborhood, :cep, :address_city, :address_state, :country_id, :addresseable_type, :addresseable_id, :_destroy)
    end
end
