的Rails 3 - 保存它通過嵌套屬性

Question

屬於對方，我不能讓怎麼做的一件事寥寥數款。我有機型用戶，教師，TeacherEducation。 老師教育屬於老師,老師屬於用戶。我想保存用戶，老師和老師教育在我的控制器中的user.save在一行中。那可能嗎？如果沒有，那麼哪個更好的方法來保存呢？

class User < ActiveRecord::Base 
    attr_accessible ..., 
        :teacher_attributes 
    has_one :teacher 
    accepts_nested_attributes_for :teacher 
end 

class Teacher < ActiveRecord::Base 
    belongs_to :user 
    has_one :teacher_education 
    accepts_nested_attributes_for :teacher_education 
end 

class TeacherEducation < ActiveRecord::Base 
    belongs_to :teacher 
end 

現在沒有TeacherEducation我有這樣的說法

<%= form_for @user, :url => create_teacher_url, :html => {:class => "form-horizontal"} do |f| %> 
    <%= field_set_tag do %> 
    <%= f.fields_for :teacher do |builder| %> 
    # Fields of teacher 
    <% end %> 
    # Fields of user 
<% end %> 

我控制器

class AdminsController < ApplicationController 
    def new_teacher 
    @user = User.new 
    teacher = @user.build_teacher 
    ... 
    end 

    def create_teacher 
    user = User.new(params[:user]) 

    if user.save 
    ... 
    end 
    end 
end 

Answer 1

這應該工作，我想..

<%= form_for @user, :url => create_teacher_url, :html => {:class => "form-horizontal"} do |f| %> 
    <%= field_set_tag do %> 
    <%= f.fields_for :teacher do |builder| %> 
     # Fields of teacher 
     <%= builder.fields_for :teacher_education do |edu_fields| %> 
     # Fields of teacher_education 
     <% end %> 
    <% end %> 
    # Fields of user 
<% end %>
