嵌套属性不保存，但ID可以

Question

我一直在尝试根据两个模型在一个表单上创建一个新记录来保存。截至目前，代码使用正确的ID在表中创建记录，但表格输入中没有保存值。模型如下：

    class Account < ActiveRecord::Base
    attr_accessible :alt_email, :c_address_id, :company, :do_not_call, :email, :first_name, :last_name, :mobile, :phone, :salutation, :subscribe, :title
    belongs_to :user
    validates :user_id, presence: true
    has_many :account_addresses
    has_many :addresses, through: :account_addresses

    #accepts_nested_attributes_for :addresses, allow_destroy: false
    attr_accessor :house, :street, :street2, :city, :state, :zipcode

    end



    class AccountAddress < ActiveRecord::Base
    attr_accessible :account_id, :address_id, :deleted
    belongs_to :account
    belongs_to :address
    end

    class Address < ActiveRecord::Base
    attr_accessible :city, :country, :full_address, :geo_verified, :house, :latitude, :longitude, :state, :street, :street2, :zipcode
    has_many :account_addresses
    has_many :accounts, through: :account_addresses


    def self.create_from_user(opts)
     a = Address.new
     a.house = opts[:house]
     a.street = opts[:street]
     a.street2 = opts[:street2]
     a.city = opts[:city]
     a.state =  opts[:state]
     a.zipcode = opts[:zipcode]
     a.country = opts[:country]


     a.save
     return a
      end
     end

create的控制器代码如下：

    def create
    success = false
    @account = current_user.accounts.new
    account_saved = @account.save

    @address = Address.create_from_user({house: @account.house, street: @account.street, street2: @account.street2,
                                     city: @account.city, state: @account.state, zipcode: @account.zipcode})

    address_saved = @address.errors.none?

    if account_saved && address_saved
     account_address = AccountAddress.new
     account_address.account_id = @account.id
     account_address.address_id = @address.id
     account_address.save
     success = true
    else
     success = false
    end

    respond_to do |format|
     if success
      format.html { redirect_to @account, notice: 'Customer was successfully created.' }
      format.json { render json: @account, status: :created, location: @account }
     else
      format.html { render action: "new" }
      format.json { render json: @account.errors, status: :unprocessable_entity }
    end
    end
    end

我看着使用accepts_nested_attributes_for执行此操作，但没有看到这对关系有何影响。对此以外的建议持开放态度。

查看尾部日志，它正在处理插入，如创建记录所示，但值显示

VALUES（？，？，？，？，？，？，？，？，？，？，？，？，？）

表单

没什么特别之处

提前感谢您的协助。
