麻煩與Rails的HAS_ONE協會

Question

我已經好幾個小時難住了這個問題，現在，我希望有人能幫助我弄清楚爲什麼這個代碼不工作。

我試圖做的是建立與特定用戶相關聯的賬戶。我可以創建一個用戶，但是當我去創建帳戶時，它看起來不像表單發佈到我的控制器中的create方法（表單數據的數組在我的瀏覽器欄中顯示爲附加到帳戶/新） 。

這裏是我的模型：

class User < ActiveRecord::Base 
    attr_accessible :email_address, :password, :password_confirmation 
    has_secure_password 
    has_one :account, dependent: :destroy 

    before_save {|user| user.email_address = email_address.downcase} 

我的賬戶模型：

class Account < ActiveRecord::Base 
    attr_accessible :cell_phone, :first_name, :home_phone, :last_name, :middle_initial, :work_phone 
    belongs_to :user 
    has_many :addresses 
    has_many :orders 
    has_many :items 

    #strip digits and return string of numbers 
    before_save do |account| 
    account.cell_phone = cell_phone.gsub(/\D/,'') 
    account.home_phone = home_phone.gsub(/\D/,'') 
    account.work_phone = work_phone.gsub(/\D/,'') 
    end 

    before_save do |account| 
    account.first_name = first_name.capitalize 
    account.last_name = last_name.capitalize 
    account.middle_initial = middle_initial.capitalize 
    end 

在我的用戶控制器（這工作正常）：

def new 
    if signed_in? 
     @user = current_user 
     redirect_to @user 
    else 
     @user = User.new 
    end 
    end 

    def create 
    @user = User.new(params[:user]) 
    if @user.save 
     sign_in @user 
     redirect_to new_account_path 
    else 
     flash[:error] = "Sorry, something went wrong" 
     render 'new' 
    end 
    end 

我的賬戶控制器（我覺得問題是這樣的）：

class AccountsController < ApplicationController 
    #before_filter :get_current_user 
    before_filter :signed_in_user 

    def new 
    @user = current_user 
    @account = @user.build_account(params[:account]) 
    end 

    def create 
    @user = current_user 
    @account = @user.build_account(params[:account]) 
    if @account.save 
     flash[:success] 
     redirect_to user_path(current_user) 
    else 
     flash[:error] 
     redirect_to root_path 
    end 
    end 

我有CURRENT_USER和sign_in作爲一個輔助文件的方法。

而且，最後，我的賬戶形式提前對您有所幫助

<%= form_for(@account) do |form| %> 
    <%= render 'shared/user_form_error_messages', object: form.object %> 

    <%= form.label :first_name, "First Name" %> 
    <%= form.text_field :first_name %> 

    <%= form.label :middle_initial, "Middle Initial (optional)" %> 
    <%= form.text_field :middle_initial %> 

    <%= form.label :last_name, "Last Name" %> 
    <%= form.text_field :last_name %> 

    <%= form.label :home_phone, "Home Phone" %> 
    <%= form.text_field :home_phone %> 

    <%= form.label :cell_phone, "Cell Phone" %> 
    <%= form.text_field :cell_phone %> 

    <%= form.label :work_phone, "Work Phone" %> 
    <%= form.text_field :work_phone %> 

    <%= form.submit "Complete Account", class:"btn" %> 

<% end %> 

感謝。我一直在使用谷歌搜索的例子，閱讀rdocs，並嘗試了一堆不同的東西。如果有人能解釋爲什麼我的代碼不起作用（而不是僅僅給我答案），我會非常感激。

Answer 1

對不起，我第一次被誤解的問題。但是，您似乎希望將現有的user對象與新的account關聯起來。這是一個可以幫助你的鏈接。

大問題聲明，但簡明扼要的回答。讓我知道它是否對你有幫助。

希望這將幫助你在你的代碼嵌套的建設情況。 在accountscontroller，

def new 
    @user = current_user 
    @account = @user.accounts.build(params[:account]) 
    end 

    def create 
    @user = current_user 
    @account = @user.accounts.build(params[:account]) 
    if @account.save 
     flash[:success]
