Question

我正在为使用设备身份验证的用户创建嵌套注册表单而烦恼。表单正在创建一个新的所有者，但它不会创建任何新用户。

以下是我的模特：

User.rb

class User <  ActiveRecord::Base
  has_one :worker
  has_one :owner
end

Owner.rb

class Owner < ActiveRecord::Base
  belongs_to :user
  accepts_nested_attributes_for :user
  attr_accessible :name, :website, :user_attributes, :user
end

所有者控制器的一部分：

class OwnersController < ApplicationController

  def show
   @owner = Owner.find(params[:id])
  end

  def new
   @owner = Owner.new
  end

  def create
   @owner = Owner.create(params[:owner])
   if @owner.save
    flash[:notice] = "Owner created"
    redirect_to(:action => 'list')
   else
    render('new')
   end
  end

end

我的老板表格：

<%= link_to("<< Back to List", {:action => 'list'}, :class => 'back-link') %>

<div class="subject new">
  <h2>Create owner</h2>

  <%= form_for(:owner, :url => {:action => 'create'}, :html => {:multipart => true} ) do |f| %>
    </tr>
    <th>Name:</th>
    <td><%= f.text_field(:name) %></td>
    </tr>
    </tr>
    <th>Website:</th>
    <td><%= f.text_field(:website) %></td>
    </tr>
    <%= fields_for :user do |form| %>
      <%= form.text_field(:email) %>
      <%= form.password_field(:password) %>
      <%= form.password_field(:password_confirmation) %>
    <% end %>

    <div class="form-buttons">
      <%= submit_tag("Creat owner") %>
    </div>

  <% end %>
</div>

Answer 1

似乎你需要

<%= f.fields_for :user do |form| %>

你有

的地方

<%= fields_for :user do |form| %>

（原始答案）

你的意思是

@owner = Owner.create(params[:owner])

在create method? (Notice the lower case 'o' in @ owner`）
