Question

我已经被这个问题困扰了几个小时了，我希望有人可以帮我弄清楚为什么这段代码无效。

我要做的是创建一个与特定用户关联的帐户。我可以创建一个用户，但是当我去创建帐户时，它看起来不像是在我的控制器中发布到create方法的表单（表单数据数组显示在我的浏览器栏中附加到accounts / new）。

以下是我的模特：

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}

我的帐户模型：

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

在我的用户控制器中（这可以正常工作）：

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

我的账户控制员（我觉得问题出在这里）：

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

我将current_user和sign_in作为Helper文件中的方法。

最后，我的账户表格

<%= 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 %>

提前感谢您的帮助。我一直在谷歌搜索示例，阅读rdocs并尝试了很多不同的东西。如果有人能够解释为什么我的代码不起作用（而不仅仅是给我答案），我将非常感激。

在@thesis请求中，当我点击表单上的“提交”时，这是我日志的输出：

抱歉，我先误解了这个问题。但是，您似乎希望将现有user对象与新account相关联。这是一个可以帮助你的链接。

希望这可以帮助您在代码中构建嵌套实例。在accountscontroller中，

  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]

在Rails中使用has_one关联时出现问题
