我在我的应用程序中定义了以下型号Rails 3个中嵌套表格 - 多级
- 用户
- 简介
- 地址
这里是我的用户模型:
class User < ActiveRecord::Base
# Include default devise modules. Others available are:
# :token_authenticatable, :encryptable, :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
# Setup accessible (or protected) attributes for your model
attr_accessible :email, :password, :password_confirmation, :remember_me, :profile_attributes
has_one :profile
accepts_nested_attributes_for :profile
end
这是我的个人资料模型:
class Profile < ActiveRecord::Base
attr_accessible :first_name, :last_name, :organization, :telephone_number, :user_id, :address_attributes
belongs_to :user
has_one :address
accepts_nested_attributes_for :address
end
这是我的地址模型:
class Address < ActiveRecord::Base
attr_accessible :street, :street_cont, :city, :state, :zip_code
belongs_to :profile
end
我使用的设计进行验证所以我认为我已在登记以下内容:
<% resource.build_profile %>
<h2>Sign up</h2>
<%= form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f| %>
<%= devise_error_messages! %>
<p><%= f.label :email %><br />
<%= f.email_field :email %></p>
<p><%= f.label :password %><br />
<%= f.password_field :password %></p>
<p><%= f.label :password_confirmation %><br />
<%= f.password_field :password_confirmation %></p>
<%=f.fields_for :profile do |profile_form| %>
<p><%= profile_form.label :first_name %><br />
<%= profile_form.text_field :first_name %></p>
<p><%= profile_form.label :last_name %><br />
<%= profile_form.text_field :last_name %></p>
<p><%= profile_form.label :organization %><br />
<%= profile_form.text_field :organization %></p>
<p><%= profile_form.label :telephone_number %><br />
<%= profile_form.text_field :telephone_number %></p>
<%=f.fields_for :address do |address_form| %>
<p><%= address_form.label :street %><br />
<%= address_form.text_field :street %></p>
<p><%= address_form.label :street_cont %><br />
<%= address_form.text_field :street_cont %></p>
<p><%= address_form.label :city %><br />
<%= address_form.text_field :city %></p>
<p><%= address_form.label :state %><br />
<%= address_form.text_field :state %></p>
<p><%= address_form.label :zip_code %><br />
<%= address_form.text_field :zip_code %></p>
<% end %>
<% end %>
<p><%= f.submit "Sign up" %></p>
<% end %>
<%= render :partial => "devise/shared/links" %>
的形式呈现正确的,但是当我查看我看到的地址字段的来源:
<input id="user_address_street" name="user[address][street]" size="30" type="text" />
的型材断面我看到:
<input id="user_profile_attributes_first_name" name="user[profile_attributes][first_name]" size="30" type="text" />
当我保存表单,用户和配置文件保存到数据库中,但没有地址。我很明显可能在模型关系上做错了事,但我不知道如何去解决这个问题。
任何帮助,将不胜感激。
你为什么要使用嵌套的HTML表单?如果不是功能上不正确的话,我认为这在逻辑上是不正确的。看到http://stackoverflow.com/questions/379610/can-you-nest-html-forms – Gal 2011-05-11 19:27:41
