在rails中更新嵌套属性时的问题

我在更新具有嵌套属性的对象时遇到了一些问题。在rails中更新嵌套属性时的问题

我的模型对象：

用户

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

我有定义的操作update在用户控制器是这样的：

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

用于PortalUser控制器更新动作也被定义：

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

最后我有一个Profile控制器承载嵌套形式：

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

查看个人资料的操作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 %>

当我进入编辑页面时，我可以看到加载到表单中的用户信息（包括@user和@portal_user），但是当我编辑表单并发送更新时，什么也没有发生！

为了帮助你发现我的问题，这里的原点是“追踪”（在此我试图重新命名为用户名字段从改变Amokrane到AMK：

Started POST "https://stackoverflow.com/users/980190962" for 127.0.0.1 at 2011-02-13 19:38:05 +0100

这可能是很明显的东西给我是比较新的轨道！

谢谢！

好吧！我刚才发现问题出在哪里了！我有一些额外的验证软件写n在我的PortalUser模型中，并没有更新，因为我没有填写所有必要的字段。
