has_oneの関係を実装できません

Question

アカウントに1つの請求先住所を持つことを許可するアカウント管理システムを作成しようとしています。私はアカウントとアドレスが独自のコントローラとモデルを持つことを望んでいます。管理者ユーザーは新しいアカウントを作成し、このアカウントの新しい請求先住所を作成するためにリダイレクトされます。最初の部分は機能し、私はアカウントを作成することができますが、2番目はaccount_id属性をアドレステーブルに保存するだけです。以下は私のコードです：

accounts_controller

class AccountsController < ApplicationController 
def new 
    @account = Account.new 
end 
def create 
    @account = Account.new(params[:account]) 
    @account.build_address 
    if @account.save 
    flash[:success] = "Customer Account has been successfully created!" 
    redirect_to '/newaddress' 
    else 
    render 'new' 
    end 
end 
end 

addresses_controller

class AddressesController < ApplicationController 
    def new 
    @address = Address.new 
    end 
    def create 
    @account = Account.find(params[:account]) 
    @address = @account.create_address(params[:address]) 
    redirect_to root_path 
    end 
end 

account_model

class Account < ActiveRecord::Base 
    has_one :address 
    accepts_nested_attributes_for :address 
    attr_accessible :contactFirstName, :contactLastName, :contactEmail, :contactPhone, :business_name 
end 

address_model

class Address < ActiveRecord::Base 
    attr_accessible :city, :state, :street, :zipCode 
    belongs_to :account 
end 

私はまた、以下に、最終

resources :accounts do 
    resources :addresses 
end 

私のroutes.rbをファイルに次が（私はプログラミングやレールにまだ新しいですので、私は投稿relavantテーブル

create_table "accounts", :force => true do |t| 
    t.string "contactEmail" 
    t.string "contactFirstName" 
    t.string "contactLastName" 
    t.string "contactPhone" 
    t.datetime "joinDate" 
    t.string "business_name" 
    t.datetime "created_at" 
    t.datetime "updated_at" 
end 
create_table "addresses", :force => true do |t| 
    t.string "city" 
    t.string "state" 
    t.string "street" 
    t.string "zipCode" 
    t.integer "account_id" 
    t.datetime "created_at" 
    t.datetime "updated_at" 
end 

のスキーマです追加

追加新しいアカウントページを開き、新しいアドレスページに移動したときのログを追加しました。 [：アカウント]

Answer 1

として簡単に見て、あなただけのparams渡している、テール・ログを、あなたは、あなたがnewaddress投稿するときことを今見ることができますが、ログを追加

class AddressesController < ApplicationController 
def new 
    @address = Address.new 
    end 
def create 
    @account = Account.find(params[:account]) 
    @address = @account.create_address(params[:address]) 
    redirect_to root_path 
end 
end 

尻を必要とするものを参照してください

Parameters: {"address"=>{"city"=>"Boston", "street"=>"123 Main St", "zipCode"=>"02222", "state"=>"MA"}, "commit"=>"Create", "authenticity_token"=>"lJG89TIjcJighmFUWLg1uR9sJq0CHLvceeLH9QNocGY=", "utf8"=>"✓"} 

とあなたのコントローラ

def create 
@account = Account.find(params[:account]) 
@address = @account.create_address(params[:address]) 
redirect_to root_path 

を持っています10

エンド

あなたは何@account = Account.find（のparams [：アカウント]）が存在しない見ることができるように

だからあなたはアカウントがnullの場合、フォームまたはキャッチするACCOUNT_IDで隠しフィールドを追加することができます他の方法は、あなたのアプリに依存します。アドレス：Addressクラス内で

Answer 2

ラインは（_attributesを取る）私には間違っているになります。フォームがfields_for使って、同じページ上にある場合

class Address < ActiveRecord::Base 
    attr_accessible :city, :state, :street, :zipCode 
    belongs_to :account 
end
