ruby-on-rails - Rails 3嵌套表格

Question

我有一个人模型和一个地址模型:

class Person < ActiveRecord::Base
  has_one :address
  accepts_nested_attributes_for :address
end


class Address < ActiveRecord::Base
  belongs_to :person
end

在我的人员 Controller 中，我的新操作中包含 @person.build_address。我的表格构建正确。问题是，当我提交表单时，会创建一个人记录和一个地址记录，但是它们没有通过“人”表中的address_id列进行链接。

我在 Controller 中错过了一步吗？

谢谢!

新 Action
更新

def new
    @person = Person.new
    @person.build_address

    respond_to do |format|
      format.html # new.html.erb
      format.xml  { render :xml => @person }
    end
  end

表格代码
更新

<%= form_for(@person) do |f| %>
  <% if @person.errors.any? %>
    <div id="error_explanation">
      <h2><%= pluralize(@person.errors.count, "error") %> prohibited this person from being saved:</h2>

      <ul>
      <% @person.errors.full_messages.each do |msg| %>
        <li><%= msg %></li>
      <% end %>
      </ul>
    </div>
  <% end %>

  <div class="field">
    <%= f.label :first_name %><br />
    <%= f.text_field :first_name %>
  </div>
  <div class="field">
    <%= f.label :last_name %><br />
    <%= f.text_field :last_name %>
  </div>
  <div class="field">
    <%= f.label :email %><br />
    <%= f.text_field :email %>
  </div>
  <div class="field">
    <%= f.label :telephone %><br />
    <%= f.text_field :telephone %>
  </div>
  <div class="field">
    <%= f.label :mobile_phone %><br />
    <%= f.text_field :mobile_phone %>
  </div>
  <div class="field">
    <%= f.label :date_of_birth %><br />
    <%= f.date_select :date_of_birth %>
  </div>
  <div class="field">
    <%= f.label :gender %><br />
    <%= f.select(:gender, Person::GENDER_TYPES) %>
  </div>
  <div class="field">
    <%= f.label :notes %><br />
    <%= f.text_area :notes %>
  </div>
  <div class="field">
    <%= f.label :person_type %><br />
    <%= f.select(:person_type, Person::PERSON_TYPES) %>
  </div>

<%= f.fields_for :address do |address_fields| %>
 <div class="field">
    <%= address_fields.label :street_1 %><br />
    <%= address_fields.text_field :street_1 %>
  </div>
 <div class="field">
    <%= address_fields.label :street_2 %><br />
    <%= address_fields.text_field :street_2 %>
  </div>
<div class="field">
    <%= address_fields.label :city %><br />
    <%= address_fields.text_field :city %>
  </div>
 <div class="field">
    <%= address_fields.label :state %><br />
    <%= address_fields.select(:state, Address::STATES) %>
  </div>
<div class="field">
    <%= address_fields.label :zip_code %><br />
    <%= address_fields.text_field :zip_code %>
  </div>
<% end %>
  <div class="actions">
    <%= f.submit %>
  </div>
<% end %>

Answer 1

您需要在自己的accepts_nested_attributes_for :address模型上安装Person才能正常工作。然后，您可以在create操作中执行以下操作:

def create
  @person = Person.new(params[:person])
  ...
end

然后，Rails将负责其余的工作。

更新:如果 address_id列在 people表中，则它应该是 belongs_to :address，而不是 has_one :address
