我遇到顯示嵌套控制器的值的問題。我可以更新該字段,我只是看不到顯示頁面上的值。我認爲這是Devise的一個問題。顯示來自嵌套窗體的值的問題
我的用戶模型如下:
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
我的頁面模式:
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
在我的用戶#表明我有這樣的:
<p>
<strong>Tagline</strong>
<%= @user.tagline %>
</p>
我得到一個未定義的方法。也試過,@ pages.tagline等
我不覺得我需要修改我的控制器?你能幫我嗎?
謝謝你,非常有幫助。 – 2011-05-09 17:44:03
