我在嵌套控制器中显示值时遇到问题。我可以很好地更新字段,我只是看不到显示页面上的值。我认为这是Devise的一个问题。

我的用户模型如下:

class User < ActiveRecord::Base
  has_one :page
  accepts_nested_attributes_for :page, :allow_destroy => true

 devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

  # Setup accessible (or protected) attributes for your model
  attr_accessible :email, :password, :password_confirmation, :remember_me, :name


  has_friendly_id :name, :use_slug => true, :strip_non_ascii => true
  validates_presence_of :name
  validates_uniqueness_of :name
  validates_uniqueness_of  :email, :case_sensitive => false

 #creates a new page on user create if one doesn't exist
  def after_initialize
      self.build_page if self.page.nil?
  end

  end

我的网页型号:

class Page < ActiveRecord::Base
  belongs_to :user
  attr_accessible :tagline, :about, :email, :phone, :website, :blog, :user,               
end

的routes.rb

Ahoy::Application.routes.draw do

  resources :users, :path => '/' do
    resource :page
  end

  devise_for :users, :controllers => { :registrations => "registrations"}

  get "home/index"
  get "home/about"

  root :to => "home#index"

end

在我的用户中#show我有这个:

<p>
    <strong>Tagline</strong>
    <%= @user.tagline %>
</p>

我得到一个未定义的方法。还试过,@ pages.tagline等。

我认为我不需要修改我的控制器?你能帮忙吗?

tagline方法在Page中定义,因此它应为@user.page.tagline
