Ruby on rails RubyonRails 2.3中的嵌套属性

根据这一点，我尝试使用嵌套表单

我有以下型号：

class User < ActiveRecord::Base
has_one :customer
accepts_nested_attributes_for :customer_attributes
attr_accessible  :customer_attributes, :email, :login, 
                 :password, :password_confirmation 


class Customer < ActiveRecord::Base
  belongs_to :user
end

我做错了什么

编辑：我变了

接受客户属性的嵌套属性

到

现在我得到了：

Can't mass-assign these protected attributes: customer

并仅在用户表中插入

编辑#2： 现在，用户类如下所示：

class User < ActiveRecord::Base
has_one :customer
accepts_nested_attributes_for :customer
attr_accessible  :customer, :email, :login, 
                 :password, :password_confirmation 

编辑3：以防万一。这是我的申请表：

<%= error_messages_for :user %>
<% form_for :user do |f| -%>
<p><label for="login">Login</label><br/>
<%= f.text_field :login %></p>

<p><label for="email">Email</label><br/>
<%= f.text_field :email %></p>

<p><label for="password">Password</label><br/>
<%= f.password_field :password %></p>

<p><label for="password_confirmation">Confirm Password</label><br/>
<%= f.password_field :password_confirmation %></p>

<% f.fields_for :customer do |c| %>

  <p><%= c.label :first_name %><br>
  <%= c.text_field :first_name %></p>
  <p><%= c.label :last_name %><br>
  <%= c.text_field :last_name %></p>
  <p><%= c.label :phone %><br>
  <%= c.text_field :phone %></p>
  <p><%= c.label :date_of_birth %><br>
  <%= c.text_field :date_of_birth %></p>
  <p><%= c.label :avatar %><br>
  <%= c.text_field :avatar %></p>
 <% end %>

<p><%= submit_tag 'Sign up' %></p>
<% end -%>

改变

accepts_nested_attributes_for :customer_attributes

到

您必须为要处理的关系设置accepts_nested_attributes_。有关更多示例，请参见

class User < ActiveRecord::Base
  has_one :customer
  accepts_nested_attributes_for :customer
  attr_accessible  :customer, :email, :login, 
             :password, :password_confirmation

有一个：顾客 接受客户的\u嵌套\u属性\u 属性可访问：客户，：电子邮件，：登录， ：密码，：密码\u确认

希望这有帮助

在第一封邮件中添加了一些详细信息您确定是Rails 2.3吗？看起来不是这样。。。显示其他详细信息。。。就像您正在使用的表单和控制器一样，Ruby Enterprise Edition的版本是2.3.8

<%= error_messages_for :user %>
<% form_for :user do |f| -%>
<p><label for="login">Login</label><br/>
<%= f.text_field :login %></p>

<p><label for="email">Email</label><br/>
<%= f.text_field :email %></p>

<p><label for="password">Password</label><br/>
<%= f.password_field :password %></p>

<p><label for="password_confirmation">Confirm Password</label><br/>
<%= f.password_field :password_confirmation %></p>

<% f.fields_for :customer do |c| %>

  <p><%= c.label :first_name %><br>
  <%= c.text_field :first_name %></p>
  <p><%= c.label :last_name %><br>
  <%= c.text_field :last_name %></p>
  <p><%= c.label :phone %><br>
  <%= c.text_field :phone %></p>
  <p><%= c.label :date_of_birth %><br>
  <%= c.text_field :date_of_birth %></p>
  <p><%= c.label :avatar %><br>
  <%= c.text_field :avatar %></p>
 <% end %>

<p><%= submit_tag 'Sign up' %></p>
<% end -%>

  def signup
    @user = User.new(params[:user])
    return unless request.post?
    @user.save!
    self.current_user = @user
    redirect_back_or_default(:controller => '/account', :action => 'index')
    flash[:notice] = "Thanks for signing up!"
  rescue ActiveRecord::RecordInvalid
    render :action => 'signup'
  end

accepts_nested_attributes_for :customer_attributes

accepts_nested_attributes_for :customer

class User < ActiveRecord::Base
  has_one :customer
  accepts_nested_attributes_for :customer
  attr_accessible  :customer, :email, :login, 
             :password, :password_confirmation
