在rails中更新嵌套屬性時的問題

我在更新具有嵌套屬性的對象時遇到了一些問題。在rails中更新嵌套屬性時的問題

我的模型對象：

用戶

class User < ActiveRecord::Base 
    has_one :portal_user 

    accepts_nested_attributes_for :portal_user 

    validates_presence_of :username 
end

PortalUser

class PortalUser < ActiveRecord::Base 
    belongs_to :user,:dependent => :destroy, :foreign_key => :user_id 
end

我有定義的操作update在用戶控制器是這樣的：

class UsersController < ApplicationController 
    # PUT /users/1 
    # PUT /users/1.xml 
    def update 
    @user = User.find(params[:id]) 

    respond_to do |format| 
     if @user.update_attributes(params[:user]) 
     format.html { redirect_to(@user, :notice => 'User was successfully updated.') } 
     format.xml { head :ok } 
     else 
     flash[:error] = "Error while updating personnal information." 
     format.html { render :action => edit_profiles_path } 
     format.xml { render :xml => @user.errors, :status => :unprocessable_entity } 
     end 
    end 
    end 
end

用於PortalUser控制器更新動作也被定義：

class PortalUsersController < ApplicationController 

    def update 
    @portal_user = PortalUser.find(params[:id]) 

    respond_to do |format| 
     if @portal_user.update_attributes(params[:portal_user]) 
     format.html { redirect_to(@portal_user, :notice => 'PortalUser was successfully updated.') } 
     format.xml { head :ok } 
     else 
     flash[:error] = "Error while updating PortalUser." 
     format.html { render :action => edit_profiles_path } 
     format.xml { render :xml => @portal_user.errors, :status => :unprocessable_entity } 
     end 
    end 
    end 

end

最後我有一個Profile控制器承載嵌套形式：

class ProfilesController < ApplicationController 
    def edit 
    # Note: I am using a hard coded Id on purpose. 
    @user = User.find(980190962) 
    end 
end

查看個人資料的操作edit：

<%= form_for @user do |f| %> 

      <%= f.fields_for :portal_user do |f_portal_user| %> 
      <%= f_portal_user.label :firstname %> <br/> 
      <%= f_portal_user.text_field :firstname %> <br/> 

      <%= f_portal_user.label :lastname %> <br/> 
      <%= f_portal_user.text_field :lastname %> <br/> 
      <% end %> 

      <%= f.label :username %> <br/> 
      <%= f.text_field :username %><br/> 

      <%= f.fields_for :portal_user do |f_portal_user| %> 
      <%= f_portal_user.label :phone %> <br/> 
      <%= f_portal_user.text_field :phone %><br/> 

      <%= f_portal_user.label :cellular_phone %> <br/> 
      <%= f_portal_user.text_field :cellular_phone %><br/> 
      <% end %> 

      <%= submit_tag "Update" %> 
    <% end %>

當我進入編輯頁面時，我可以看到加載到表單中的用戶信息（包括@user和@portal_user），但是當我編輯表單併發送更新時，什麼也沒有發生！

爲了幫助你發現我的問題，這裏的原點是「追蹤」（在此我試圖重新命名爲用戶名字段從改變Amokrane到AMK：

這可能是很明顯的東西給我是比較新的軌道！

謝謝！

好吧！我剛纔發現問題出在哪裏了！我有一些額外的驗證軟件寫n在我的PortalUser模型中，並沒有更新，因爲我沒有填寫所有必要的字段。
